CleanCrete technical specifications

Compression tests prove that CleanCrete is as strong as conventional concrete. Durability is the cornerstone of sustainable design and construction and as they become available, we will share test results that prove CleanCrete products have remarkably enhanced durability. We believe that CleanCrete offers the most environmentally-sensitive concrete available. At Clean Concrete Technologies, we take a stand against greenwashing and companies that advertise misleading information about the environmental impact of their products.
