Applications of Waterproofing Chemicals

Waterproofing Chemicals

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 structures, waterproofing is carried out with coatings and membranes. These are added 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 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.



There are few garments and tents that are designed in a manner to deliver better protection results from water. These protective textiles come in the form of jackets, raincoats and hiking apparel. These clothing items are known for their water resistance. Water proof clothing unlike water resistant clothing, have a water repelling coating, which prevents ingress of water as the seams are sealed. Water proof textiles are wind resistant as well due to the purpose of their use in harsh weather conditions. Coated Membranes made from polyurethane and teflon, prevent liquid water from passing through the fabric.


Other Objects

Waterproofing chemicals find applications in various objects, such as cosmetics, paper packaging, 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 stand, which prevent the entry of water and protects the device. Carbon nanocones have gained popularity due to their high-water repelling property.
