With over 75 years experience in manufacturing reliable coatings, Pure Asphalt has created a line of “waterproofing” foundation coatings that are durable, flexible and easy to apply. These single component heavy bodied protective coatings are designed for economical airless spray application to provide a smooth, tough, membrane that resists water penetration. Unlike “dampproof” coatings that offer short term protection, SureDry foundation coatings are extremely elastomeric, will not become brittle even at low temperatures, and provide long term warranted protection

Signs of structural cracks include horizontal cracks, cracks ” or greater, and offset cracks. These are just a few of signs of structural damage. If there is any question of structural problems, a professional repair contractor should be called. Hydraulic cement and urethane caulk consistently fail in a few short years. Expansion and contraction of the wall, though minimal, cause service repairs to shadow crack and leak again. With urethane or epoxy injection this does not occur. Crack injection, properly installed, should last the life of the structure. It is rare that a crack is so small it cannot be injected with Sure Dry’s crack injection system. Cracks which are barely visible to the naked eye are good candidates for crack injection. SureDry provides product support through inside tech sales, field training, and instructional videos
