Rapidite Waterproofing Powder

Water resistance or proofing is an important factor in health and comfort of building occupants. Several texts on concrete construction describe the methods for achieving water proofing. The term waterproof describes concrete and masonary is completely impervious to water and water vapour, whether or not the water is under pressure. Water proof construction implies the use of a membrane or a film that provides a barrier and covers all surface pores or capillaries. The term water repellent describes concrete or masonary that repells water without significantly reduced permeability of the structure to the passage of water vapour.
