About Waterproofing

Waterproofing . In construction structure waterproofing is carried out with coatings and membranes. These are added or applied for structural integrity and protection of contents. Waterproofing chemicals play a vital role in construction of buildings, where they create an envelope, thereby providing a controlled environment.

The foundations, roofs,Toilets,Basements 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, ethylene 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.
