Bitumen coating is applied to footing foundations primarily for waterproofing and protection against moisture. It creates a barrier that prevents water penetration into the foundation, helping to avoid potential damage caused by water seepage, corrosion, and other related issues. This protective layer also enhances the durability and longevity of the foundation by reducing the risk of deterioration due to environmental factors. Mainly to prevent ASR (Alkali–silica reaction), in areas near to beach.
