Historically, traditional waterproofing methods involve the placement of a barrier or membrane between the concrete and water. Unlike membranes and other surface systems, crystalline waterproofing is designed to make the concrete itself waterproof. This course discusses how crystalline waterproofing technology provides a high level of performance to concrete structures and what design professionals need to know in order to specify and understand how this chemical technology can improve building projects, cut costs, and help earn LEED® credits.
