Azo-Grout™ 443-C is a low viscosity, hydrophobic polyurethane used for soil stabilization in a variety of water-bearing soils. The low viscosity characteristics of the Azo-Grout™ 443-C with Azo-Cat™ 23 allow the material to penetrate the earth, adding structure and stabilization by encapsulating the granules and forming a rock-like mass.
