Silicone Water Repellent Coatings Building protects us from nature forces like rain, heat, cold, wind etc., The concrete structures on its own is porous and hence not watertight. The unprotected structures suffer from water induced damage including deterioration and corrosion caused by chlorination, oxidation and sulphation. They reduce alkalinity in concrete and turns acidic. The result, reinforcement bar catch rust and eventually expands, to drastically hamper load bearing capacity of the building structures. The continuous presence of water leads to constant dampness & humidity and promotes the growth of molds and fungus on walls and insects presence leading to health problem like asthma, skill allergies, rashes etc.,The consequent spalling of concrete plaster, flaking off expensive paint on interior/exterior of walls adversely impacts life and value of structure. If the buildings are not waterproofed during constructions, it may result in costly and hassle prone repair work in future.
