Crack and joint sealing for use in sewers and manholes | Azo-Grout™ 675

Azo-Grout™ 675 is a single-component, hydrophilic polyurethane that cures in areas where water is constantly present. Depending on the amount of water in the mixture, Azo-Grout™ 675 will vary in consistency from a resilient, rubber-like foam to a flexible gel.

The product is capable of absorbing as much as 800 percent of its own mass and then deflecting excessive water from penetrating into a structure. This unique absorption quality allows Azo-Grout 675 to seal off joints and cracks where there is heavy water inflow.
