Nexseal 1000 is a surface-applied crystalline waterproofing treatment incorporating Nexgen technology for the protection and repair of existing concrete structures against the ingress of water. Nexseal 1000 is a dry powder that when mixed with water is applied as a slurry coat to the positive or negative side of concrete substrates. Nexseal 1000 is designed to provide a permanent in-depth waterproofing solution. The Nexgen state of the art crystalline technology works over time to create an enhanced hydration reaction between cement particles and moisture that improves concrete´s own natural abilities. This reaction causes millions of long pin like crystals to form within the concrete matrix effectively stopping water penetration and waterborne contaminants permanently
