Waterproofing is a method for making a structure or an object water resistant , such that they are not affected by water . This is achieved with the help of waterproofing chemicals . These chemicals are used for waterproofing concrete , paints , paper packaging , electronics , cosmetics etc .
In construction of structure , waterproofing is carried out with coating and membranes . These are added for structural integrity and protection of contents . waterproofing chemicals play a vital role in construction of bulidings , where they create an envelope , thereby providing a controlled environment . The foundations , roofs and other areas must restrict water penetration and may have to be waterproof . the roofs of buildings are designed in slopping manner to facilitate the flow of water . The various materials and chemicals used for water proofing include polyvinyl chloride , hypalon , ethyene propylene diene monomer (EPDM )rubber , tar paper with asphalt and bituminous materials .
Another aspect of water proofing is damp proofing , It involves the construction of masonry walls along with a damp – proof course , which would prevent dampness . This is accomplished with liquid coatings , grouting , sealants , plasters , primers as well as concrete additives .
The older methods that involved high density polythene (HDPE) and polyvinyl chloride (PVC) have limitations . Whereas , the new waterproofing methods involve polymer – based materials that create seamless barriers around the periphery of the structures , owing to their high adhesivity .
Waterproofing chemicals find applications in various objects , such as cosmetics , paper packing etc . The technological advancements have made the waterproofing of electronics possible . The new technology is based on nanotechnology , unlike the convention waterproofing capsule or case . The nanotechnology coating is thousand times thinner than a hair stant , which prevent the entry of water and protects the device . Carbon nanocones have gained popularity due to their high-water repelling property .
We are sale Sika Damp-proofing slurry is a one part polymer modified cement based waterproof coating comprising of special cement based components and admixtures . When mixed with water a slurry or mortar material is produced for direct application to a variety of construction substrates .
