The methodology has been changing with the changes in the architectural designs and with the availability different building materials in construction. In the initial stages when stone was the main building construction material placed in position with mud or lime mortar the emphasis used to be to make the construction in such a way that the rain water does not collect on the roofs. Hence old architecture relied mainly on dome or slanting structures for the roofs. The slow speed of such construction and unaffordability of common man to build such structures for their own dwelling, made constant evolution and development in the construction material technology. With these developments the concepts of waterproofing also changed. Now in present day construction wherein the ordinary portland cement and its blends with puzzolonic and slag materials has come to stay a lot of alternatives are available for a builder to choose from various waterproofing systems which are compatible with the cement. There are some compounds, which are used in plastic concrete to make it less permeable to water. These compounds are known as integral <a href="http://www.permaindia.net/"><strong>waterproofing compounds</strong></a>. They are based on air-entrainment or water repellence principles. These are used as a good waterproofing precautions. This subject will require in depth discussion hence will not be taken up here. Similarly there are some water proofing techniques for vertical surfaces. These techniques are used also used for preserving heritage buildings by stopping/minimising the aging process of these buildings. This subject also will not be discussed here. Some of the well known  water proofing systems are as follows:</p> <p> </p> <ul> <li>Brick Bat Coba system or Lime Terracing</li> <li>Bituminous Treatment</li> <li>Metallic Sheet Wrapping</li> <li>Poly-urethane based Waterproofing treatment</li> <li>Epoxy Based Water proofing Treatment</li> <li>Box Type Water proofing System</li> <li>Crystalline Water Proofing System</li> <li>Membrane based Water Proofing System</li> </ul> <p> </p> <p> </p> <p><strong>Brick Bat Coba System</strong></p> <p>This system was developed during the initial stages of flat roof construction with lime mortar burnt clay brick pieces. This system involved laying of light weight mortar on the roof and spreading it to give gentle slopes for draining away the rain water immediately. The mortar consisted of light-weight brick pieces as aggregates and ground brick with lime as binding matrix. During British rule this system became more popular not because of its waterproofing efficiency but because of its efficiency in keeping the interiors cool. Some applicators developed better skills in laying this systems with neatly finished top with lines marked on top now known as IPS or with pieces of broken tiles and other ceramoic materials embedded known china mosaic. This type of system remained most popular with multi-storeyed construction in all major metro cities. The system lasts up to 15 years if done by skilful applicators. This system may be considered more from its weather proofing abilities rather than its waterproofing qualities. Once water starts going into the brickbat coba the brick pieces absorb too much of water and the roof becomes an invisible pond of water continuously causing leakage and increasing burden on the roof slab. It will be highly beneficial if brick-bat coba is laid on a flexible waterproofing membrane as water proofing as well as economical weather proofing can be achieved with this system.</p> <p> </p> <p><strong>Bituminous Treatment</strong></p> <p>Discovery of petroleum and its products and by-products has given the construction industry an indispensable product in the form of bitumen.<a href="http://www.permaindia.net/perma-bitu-coat.htm"><strong>Bitumen</strong></a> is more commonly used in the form of felt or flexible membrane formed by sandwiching jute fabric or fibreglass/polypropylene mats with chemically modified bitumen. These membranes are layed on the roofing over a bitumen primer. There are two types of membranes one is cold applied and the other hot applied which means one needs to heat the edges of the felt with a torch so that they melt and stick to the second layer in the overlap area. On the RCC flat roofs the bitumen felts have not been successful because of the unacceptable black appearance and inaccessibility of the terrace for other social uses. Technically it is not preferred because bitumen layer or felt on the terrace not only makes it watertight but also airtight. Concrete has the breathing property. It takes water/moisture and breathes out water vapour. Hindrance of this breathing property of concrete develops pore pressure, which causes blisters in the felt. After a few seasons the blisters multiply and eventually delaminate the felt from the concrete surface. Hindrance of breathing property of concrete makes it weak. But on the asbestos cement sheets and zinc sheets in factory roofs this bitumen felt is the only dependable waterproofing system. Hence all factory roofs in India adopt this water proofing system. Apart from this in waterproofing of basements from outside is very effective with bitumen felts. Bitumen primers have very successfully been used as damp-proof course in earlier days. This practice is slowly discontinued and we have a lot of cases of rising dampness, which we tend to attribute to the quality of sand.</p> <p> </p> <p><strong>Metallic Sheet Wrapping</strong></p> <p>The non-existence of suitable expansion joint filling compounds before the discovery of poly-sulphides, a complex procedure used to be adopted to treat expansion joints in concrete dams and such huge structures utilising copper sheets. An extension of that found thin copper foils and aluminium foils being used in the buildings for water proofing purposes. The absence of common joining material for metal and concrete and the weakness of the system at the joints discouraged this practice in its infancy only.</p> <p> </p> <p><strong>Poly-urethane based water proofing Treatment</strong></p> <p>Poly-urethane consists of two liquid components one is called the Base component and the other is called reactor or curing agent. Base is a polyol and the reactor is an isocyanide such as TDI MDI. There are various grades of polyols and so also there are numerous isocyanides. The combination of these two ingredients results in a formation liquid applied rigid membrane or a foam depending upon the selection. In <a href="http://www.permaindia.net/waterproofing-chemical.htm"><strong>water proofing</strong></a> this rigid liquid membrane was tried with fibreglass reinforcing mats. The systems failed because coefficients of thermal expansion of concrete and rigid PU membrane being different lateral movement or creep occurred. In UV exposure most rigid membranes became brittle and crumbled. Apart from this the application of poly-urethane coating needed very rigorous surface preparation. The surface needed to be neutralized by removing alkalinity from the concrete surface by acid itching then washing and blowtorching to make the surface bone dry. This kind of surface preparation angered the civil engineering community and the product ceased to be used as waterproofing material. Never the less continuous research in the poly-urethane gave the construction industry excellent sealant for glazing industry and foams for thermal insulations.</p> <p> </p> <p><strong>For further info visit: www.permaindia.com / www.permaindia.net  </strong><br /><strong>OR email to:info@permaindia.com</strong></p> Make Concerete Better with Waterproofing Admixtures http://www.permaindia.net/blog/make-concerete-better-with-waterproofing-admixtures_4914.htm Thu, 05 Mar 2015 12:20:04 +0530 <p>Concrete is one of the most widely used construction materials in the world and its usage is expected to keep on increasing. Admixtures are a type of chemicals that are added to concrete while mixing to modify its properties and make it better and stronger. Concrete in itself is a very strong mixture but the addition of admixtures makes it stronger, durable, waterproof, and resistant to all kinds of weathering processes. The best quality admixtures should be used to get the best results. </p> <p> </p> <p><strong>Major Reasons for Using Admixtures</strong></p> <ul> <li><span style="line-height: 1.5em;">Admixtures reduce the cost of concrete construction to a great extent.</span></li> <li><span style="line-height: 1.5em;">It helps to improve certain qualities of concrete in an effective way.</span></li> <li><span style="line-height: 1.5em;">The quality of concrete can be maintained even during bad weather conditions while mixing, transporting, placing, and curing.</span></li> </ul> <p> </p> <p><strong>What are Waterproofing Admixtures?</strong></p> <p>Admixtures are an important component of concrete. As already discussed admixtures in combination with cement, water, and other elements makes the whole mixture stronger and durable. Admixtures are also important for making the concrete waterproof so that problems like seepage do not occur in the future. Waterproofing admixtures or water resisting admixtures are like a necessity for any kind of concrete construction. Some facts about <a href="http://www.permaindia.net/admixture-for-concrete.htm"><b>Waterproofing Admixtures</b></a> are as follows:</p> <ul> <li><span style="line-height: 1.5em;">Waterproofing admixtures are based on certain type of salts such as oleic acid, stearic acid, caprylic acid and fatty acid soaps. </span></li> <li><span style="line-height: 1.5em;">They make the concrete denser and less porous.</span></li> <li><span style="line-height: 1.5em;">Waterproofing admixtures decreases the amount of water because it is absorbed by the hardened concrete.</span></li> <li><span style="line-height: 1.5em;">Waterproofing admixtures are dissolved in water and mostly sold as powder.</span></li> </ul> <p>Water seepage is a major problem in the construction industry, particularly when the buildings are constructed in rainy and damp environments. Nowadays a large number of Waterproofing Admixtures that are water resistant are used in the construction industry. These Waterproofing Admixtures block the pores of the concrete at the outer surface but do not affect the pores inside. </p> All about Stainless Steel Butt-Weld Fittings http://www.permaindia.net/blog/all-about-stainless-steel-butt-weld-fittings_4923.htm Thu, 05 Mar 2015 14:38:56 +0530 <p>Steel pipes are installed mainly for transferring solid, liquid and gas.

One such material is fly ash brick. Fly ash bricks are a kind of building material that contains class C or F type of fly ash, some specific masonry units, and water.</p> <p> </p> <p>They are then hardened with Fly Ash Bricks Hardeners. On using such chemical hardeners, the fly ash bricks’ strength increases to about 7.5 MPa to 10 MPa, thus making the fly as bricks harder than clay bricks.</p> <p> </p> <p>Fly ash brick hardeners are manufactured and supplied by many construction companies all over the world. Suppliers of Fly Ash Bricks Hardener supply good and high-quality chemicals that are used to harden the bricks and make them stronger and long-lasting.</p> <p>Properties of Fly Ash Bricks Chemical Hardener</p> <p> </p> <p>The main ingredients of fly ash bricks are fly ash, cement, quick lime, also known as lime sludge, gypsum, and aluminium powder. These chemical ingredients highly contribute to the hardening of the bricks. The autoclaving process also increases the strength of the fly ash bricks. Here are some of the properties of chemicals that work as Fly Ash Bricks Hardeners.</p> <p> </p> <p>• Gypsum Content: Gypsum contributes to a 5% proportion of the fly ash bricks. The suppliers of Fly Ash Bricks Hardeners use gypsum because it serves as a strength gainer for the bricks for the long term.</p> <p> </p> <p>• Usage Of Aluminium: The chemical reactions that take place during the hardening process on the addition of aluminium paste the AAC a unique porous structure, insulation, and lightness. This makes fly ash bricks unique and hard as compared to other concrete material bricks.</p> <p> </p> <p>• Commercial Processes Used: In the lime route process, the compositions of the fly ash bricks include 50% fly ash, 30% slaked lime, and 20% anhydrous gypsum. To this 3 or 4 times stone dust, a kind of filtering material and sand can be added. For the cement route process, the compositions of fly ash bricks include 76% of fly ash, 20% OPC and 4% anhydrite. To this 3 or 4 times of any kind of filtering material is added.</p> <p> </p> <p>The <em><strong><a href="http://www.permaindia.net/fly-ash-bricks-hardener.htm">Fly Ash Bricks Hardener Distributors</a></strong></em> offer a wide variety of fly ash bricks for construction purposes.</p> <p> </p> <p>• Fineness Of Fly Ash: Fly ash being fine has a greater available surface area for reaction with lime. This increases pozzolanic activity that increases the strength of the fly ash. However, more than 320m2/kg of fly ash should not be used to make the fly ash bricks.</p> <p> </p> <p>• Calcium Content: Fly ash brick comprising of calcium have high pozzolanic reactivity of fly ash. High calcium content results in a high pozzolanic activity that increases the hardness of the fly ash brick. C618 fly ash bricks of class C have more than 10% proportion of lime while that of class F has less than 10% proportion of lime.</p> <p> </p> <p>The Fly Ash Bricks Hardener Distributors keep in mind the various advantages as well as the disadvantages of using various chemical hardeners for manufacturing fly ash bricks and therefore provide the best quality fly ash bricks in the construction market.</p> Concrete Protective Coatings: Uses & Types http://www.permaindia.net/blog/concrete-protective-coatings-uses-types_7850.htm Thu, 26 Dec 2019 14:14:06 +0530 <p>Concrete structures which remain especially in the aggressive environment such as industrial or marine areas are having threats of chloride attack. To offer protection to the concrete structures from chloride attack protective surface coatings are used. It is able to protect any repaired or new concrete surfaces from being attacked of chemicals such as nitrous or sulphurous pollutants, in the future too. Even the access to aggressive gases and liquids can also be stopped using <em><strong><a href="http://www.permaindia.net/concrete-protective-coatings.htm" target="_blank">cement concrete hardener</a></strong></em>.</p> <p> </p> <p>Such a surface protection technique to the concrete surfaces can also be specified as –</p> <p> </p> <p>• Pore blocking and impregnation for water-repelling</p> <p>• Crack bridging and different degrees of elastic bridging at separate temperatures</p> <p>• Chemical resistant in various containment zones</p> <p>• Wear and abrasion resistant in the concrete horizontal surfaces</p> <p> </p> <p>Concrete protective coating manufacturers effectively provide hardeners for multiple structures and several exposure conditions.</p> <p> </p> <p><strong>Types of concrete coatings:</strong></p> <p> </p> <p>Generally all the concrete coatings available in the market are part of multicomponent systems. And, among those the two most common components are urethane and epoxy. But these two coatings need at least a day before return to service. Those systems which require faster curing should use methyl methacrylate and polyaspartic coatings as such coatings can return to service within a few hours.</p> <p> </p> <p><strong>The below-discussed five types of coatings are available in the market –</strong></p> <p> </p> <p>• Penetrating concrete sealers – this is the most commonly used coatings for exterior concrete surface, particularly for those which are susceptible to damage from freezing or melting conditions, and various other tough outdoor elements. Penetrating concrete sealers when dried offer a usual matter finish which protects the surface without changing its exterior.</p> <p> </p> <p>• Acrylic sealers – it protects the concrete surface by creating a thin layered protecting film. You can get the desired sheen level by using its water or solvent-based formulas. Acrylic sealers can be used for both exterior and interior areas. It is economical but less durable than polyurethanes and epoxies. But it dries quickly so makes a good choice when a minimum down time is crucial.</p> <p> </p> <p>• Polyurethanes – it is available in both solvent and water-based formulations. A number of sheens are available for its inside or outside applications. Its thickness is almost twice of the acrylic sealers. It creates long-lasting covers and thus the most suitable options for high traffic areas. It is able to offer stronger resistance to staining, scuffs and marks.</p> <p> </p> <p>• Epoxy – it makes a versatile choice by offering single or double component application. Multiple patterns or colours can be achieved by clear application of epoxies or colourful vinyl or quartz chips incorporated with the epoxies. Epoxy finishes are susceptible to UV damage so mainly used for the interior applications. Epoxy coatings are hard and resistance to abrasion and known to offer long-lasting impressions.</p> <p> </p> <p>• Concrete overlays - such protective coatings include aggregates, cement and polymer resins. It makes durable and strong coating. Due to its affordability, overlays have become very popular. It cures quickly so, you experience nominal downtime.</p> <p> </p> <p>You can choose your desired hardener by contacting the reputed concrete protective coatings suppliers of the industry.</p> Everything You Want To Know About Liquid Waterproofing Chemicals http://www.permaindia.net/blog/everything-you-want-to-know-about-liquid-waterproofing-chemicals_8466.htm Mon, 30 Mar 2020 14:29:29 +0530 <p>Water is an important resource to sustain on earth but as much as we need it, its power can even destroy many things.

Unlike the usual kinds of waterproofing chemicals that need to be dissolved in a solvent, these chemicals are very convenient in their usage. Before using the chemicals, you should stir the chemicals in the container itself. You can apply a coat of this liquid directly from the container to the wall. Wait for 4-5 hours. Now, apply another coat of this chemical on the surface.</p> The Eminent Role Of Admixtures For Concrete http://www.permaindia.net/blog/the-eminent-role-of-admixtures-for-concrete_8762.htm Thu, 28 May 2020 15:15:10 +0530 <p style="text-align: justify;">The construction and development industry cannot be imagined in the absence of concrete. The paste made up of cement and water hardens over the time to form a rock-like substance. This hard rock-like substance formed is coined as concrete. Concrete is known for its high compressive strength and relatively low tensile strength. In order to impart certain characteristics in the concrete, admixtures are added either before or during the time of batch mixing. These admixtures strengthen the concrete to withstand many challenging and adverse conditions. These admixtures give a certain functionality or peculiarity to the concrete. These products enhance the performance of the concrete by imparting strength to it so that it can combat the challenging weather conditions in an effective manner. The inclusion of these admixtures can lead to increase or decrease of the setting time, enhanced quality, resistance to sulfate, superb finish, and much more. Basically, there are two types of admixtures i.e. chemical and mineral. The chemical admixtures are available in a powdered or liquid form, whereas, the mineral ones are available in the form of a fine grain. The functionality of the concrete so formed depends on the type of concrete admixture added while the batch mixing process.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>Some of the chemical admixtures and their function are as follows-</strong></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• Water-reducing admixtures - </strong>These admixtures are added to reduce the water content of the concrete mix. This improves the workability of the concrete. Thus, the concrete having a water-reducing admixture like plasticizers, etc. require less water to be added to them in order to reach the desired results.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• Retarding admixtures -</strong> Incorporation of these types of admixtures lowers down the setting rate of the concrete. These admixtures are generally used under the hot weather conditions, as the concrete instantly sets under these conditions. Retarding admixtures prolong the setting up time of the concrete and enhance its workability during the placement.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• Accelerating admixtures - </strong>These admixtures increase the setting rate of the concrete. These admixtures are highly popular in areas prone to cold weather conditions. These admixtures speed up the construction process.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• Corrosion-inhibiting admixtures - </strong>These admixtures are generally added to the concrete mixes that are intended for jacketing steel. These admixtures slow down the rate of corrosion of the steel contained in the concrete structure.</p> <p style="text-align: justify;">Mineral admixtures for concrete are the inorganic materials having pozzolanic properties in them. Some of the mineral admixtures and their functions are as follows:</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• Fly Ash -</strong> It is widely added as an admixture to the concrete mix in order to increase its strength and reduce the cost of concrete.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• GGBFS -</strong> The full form of GGBFS is Ground Granulated Brass Furnace Slag. It is formed as a by-product during the production of steel. It is capable of partially replacing the Portland cement.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>• High reactivity Metakaolin (HRM) – </strong>As per the <a href="http://www.permaindia.net/high-performance-concrete-admixtures.htm" target="_blank">concrete admixture suppliers</a>, this mineral admixture imparts strength and durability to the concrete. The vibrant white color of this admixture makes its apt for the construction of structures in which appearance is paramount.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Thus, we can conclude that concrete admixtures play a pivotal role in the field of construction and development.</p> Free Flowing Non-Shrink Grout – Strengthen Your Constructions http://www.permaindia.net/blog/free-flowing-non-shrink-grout-strengthen-your-constructions_8767.htm Fri, 29 May 2020 10:39:53 +0530 <p style="text-align: justify;">Grout is an essential part of many construction works. It arises in many variants, chemistries, sanded or unsanded and colors. It is generally a cement or epoxy-based material that is used to fill gaps between the tile spaces. The most common delineation of cement-based <a href="http://www.permaindia.net/free-flowing-non-shrink-grout.htm" target="_blank">free-flowing non-shrink grout</a> is sanded and unsanded. The sand also provides roughly to the touch texture, versus unsanded.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">That said, if you are working with a tile that is relatively soft, and prone to scratches, such as marble, one would want to avoid sand, as a grain of sand is an aggressive scratch creating abrasive once trapped underfoot.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Unsanded grout is also known as "wall grout". It has the basics of sanded grout only without the sand. This type of grout is mainly used on ceramic tile and polished marble. It is used with grout joints that are less than 1/8". This grout should always be sealed after installation to ensure longevity and appeal.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Cement-based grouts are known to be porous, and therefore need to be sealed, else they will stain. Sealing cementitious grout is the key to preventing staining.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>High strength free-flowing non-shrink grout</strong></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Grout is a mixing powder, having well-graded aggregates cement and specialty chemical additives to empower reaching of high early strengths. When mixed with the exact amount of water, the product changes into a free-flowing grout and unlike conventional grouts, does not shrink on the setting.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>How to use:</strong></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>Surface preparation:</strong></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Eradicate all Dirt, lubricant and other bond-inhibiting materials by mechanical means (Using Wire brush). Metal Anchors and Bolts to be grouted must be de-greased with suitable solvents. Prior pouring, Surface should be bought into the dry condition. Steel should be dried, cleaned and organized thoroughly.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>Mixing:</strong></p> <p style="text-align: justify;">Mix manually or mechanically using a Putty mixer blade or paddle.</p> <p style="text-align: justify;">Ensure first that all forming, mixing, placing and clean-up materials are ready. Add the proper quantity of clean water to achieve an anticipated flow of grout.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>Application:</strong></p> <p style="text-align: justify;">Within 15 minutes after mixing, place grout into forms in a normal manner to avoid air pockets.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><strong>Different Industries that use grout</strong></p> <p style="text-align: justify;">1.

Construction chemicals are one of those modern age marvels. Generally, a construction chemical is mixed with concrete and materials during the construction process. It helps to hold all these materials together.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">These construction chemicals also serve in waterproofing solutions for the construction. They stop the concrete from having atmospheric damage. Commercial, industrial and residential structures have extensive usage of these chemicals in their construction. The workability and durability increase during construction due to these chemicals.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">There is a wide range of manufacturers for such products all over the world. Repairs and rehabilitation of buildings, concrete modification, and waterproofing solutions are where they provide their functionalities. Modern developed countries demand the usage of these chemicals in the following sectors:</span></p> <p style="text-align: justify;"><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">● Renovation and restoration of the buildings</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">● Waterproofing solutions for roofs, mines, tunnels, etc</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">● Highway constructions, bridges, and flyovers</span></p> <p style="text-align: justify;"><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Their application in these sectors ensures that these structures would be able to sustain extreme weather conditions. Due to a wide range of construction chemicals exporters, the availability of these chemicals is always stable.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">The products using construction chemicals come in a wide variety.

They are specifically built to decrease the effect of water ingression. There are two segments of waterproofing construction chemicals available in the market. They are hydrocarbons and polymers. Hydrocarbons are generally used for waterproofing solutions of roofs. They are a sticky, organic, and waterproof compound used while construction procedures.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">With changing time other chemical compounds are making their way in the market increasing the trade of the chemical industry. <a href="http://www.permaindia.net/construction-chemicals.htm" target="_blank">Construction chemical manufacturers</a> are introducing compounds like polyurethane and polyurea hybrids. These modern compounds have better application results for extreme weather conditions. They provide properties being jointless and seamless, as a result, the application results get better. With increasing demands for insulation from different customers from extreme weathered regions, manufacturers have brought polyurethane. It meets both ends of the demand by providing excellent waterproofing solutions along with insulation for the roofs and walls.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Another visionary change in this sphere was brought with the introduction of the dry-walls concept. Since waterproofing becomes a real challenge in wet areas, the dry-wall concept has shown revolutionary results. With the application of dry-walls in washing areas or washrooms, waterproofing solutions have reached higher levels of perfection.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Summarizing the whole thing we can say that the basic principle of waterproofing is the minimization of water penetration through concrete construction and we can divide it into two spheres:</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">● By using plasticizing chemicals minimizing the mixing water demand.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">● With the use of organic crystal formation while the concrete hydration process.</span></p> Water-Resistant Vs Water-Repellent Vs Waterproof: What’S The Difference? http://www.permaindia.net/blog/water-resistant-vs-water-repellent-vs-waterproof-what-s-the-difference_9358.htm Fri, 18 Sep 2020 09:41:33 +0530 <p style="text-align: justify;"><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">All the people have seen references to alternatives that are waterproof, waterproof, and water repellent. The big question is: How is it? There are several articles written on this subject and about water repellent coatings but the differences between all three words can be closely examined with a particular emphasis.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><strong><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water-Repellent:</span></strong><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water repellence is a term used to describe both water-resistant and water-proof product characteristics once a robust water repellent (DWR) is applied. If a product is branded by water repellent coatings manufacturer as "water-repellent," that means it repels the touch of water. Water repellence tests how much water pressure a material can withstand before water starts to infiltrate as an aspect of water-repellent material.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><strong><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water Resistant:</span></strong><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">The lowest degree of water safety for the three is water-resistant. If a product is labeled water-resistant, the unit itself may be designed to make it harder for water to get inside or may be filled with a very light coating that helps increase products chances of survival. Water-resistance is something you also see in watches, allowing them the ability to cope with normal rain or washing.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><strong><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Waterproof :</span></strong><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">The meaning of waterproof is very simple, but it is not the essence of it. There is currently no proven industry standard to identify a product as waterproof. As regards the rating scale, the closest thing currently available is the IP Rating (or IP Code). This scale gives products an 0-8 rating, in terms of the efficiency with which the object prevents water from entering, namely water entry.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">A risky move for many businesses can also be considered with the term waterproof. Since the word waterproof generally reflects the belief that the state is irreversible, that something 'waterproofed' can never break, regardless of the circumstance, due to water-contact.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">It's no wonder that they're mostly not used wrongly with all the debate about the proper usage and end result associated with these words. e It is also no surprise that the products that are labeled waterproof, water-resistant, or water repellent are frequently misrepresented as a result of poorly applied labeling. Since these words were used first, the word itself has almost required new meanings and a new standard to quantify the outcome such that it really reflects technology possibilities and types.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><strong><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water Repellent Solutions :</span></strong><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water repellent chemicals may be used only for the surface coating to avoid any leakage. This is a white substance that can be placed on the surface of a brush. This chemistry is used to prevent water leakage in the soil. The use of this liquid may be used to preserve and avoid water from the preservation of any material or commodity within it. You can easily get them from a <a href="http://www.permaindia.net/water-repellent-coatings.htm" target="_blank">water repellent coatings supplier</a>.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">The protection of the building by preventing water runoff is a crucial aspect of sustainable design. As a mechanism for maintaining a building and also for dealing with aesthetic elements, various water repellence technologies are developed.</span><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><br style="color: #333333; font-family: Arial, Helvetica; font-size: 11px;" /><span style="color: #333333; font-family: Arial, Helvetica; font-size: small;">Water-repellence prevents the movement of water and avoids the hydrostatic pressure that can be generated. While sheet membrane waterproofing is the oldest and most widely-used positive-side technology, many building projects worldwide use integral crystalline admixtures to waterproof concrete. Integral systems block water from either direction by working out the concrete itself as the water barrier from within.</span></p>
