Thoroseal® 501

Thoroseal® 501 waterproofing system is for waterproofing concrete and cementitious substrates. When applied to the surface of concrete or mortar, insoluble crystals are formed and developed in the water bearing capillaries, effectively blocking the passage of water and ensuring permanent water tightness throughout the life of the structure.
