Hycrete

Our technologies deliver integral waterproofing that eliminate the need for external membranes, coatings and sheeting treatments. With our solutions, concrete is batched with Hycrete liquid admixtures to achieve hydrophobic performance (less than 1% absorption under BSI-1881 122). Hycrete Admixtures transform concrete from an open network of capillaries and cracks into an ultra-low absorptivity, waterproof, protective building material.

Hycrete Admixture is Cradle to Cradle Certified by MBDC. Cradle to Cradle Certification provides a company with a means to tangibly, credibly measure achievement in environmentally- intelligent design and helps customers purchase and specify products that are pursuing a broader definition of quality.
