Repair Process

Hydra Stop 300 is a low viscosity liquid polyurethane. Once inside the crack, the Hydra Stop begins to foam and expand. This expansion completely fills the crack and stops water.

1. View video included with the kit

2. Attach surface or corner ports over the foundation crack using Poxy Paste Crack Seal & Port Adhesive

3. Cover the entire foundation crack with Poxy Paste Crack Seal & Port Adhesive

4. Inject liquid Hydra Stop 300 polyurethane crack injection resin into the foundation crack with a caulk gun

5. Place caps into the surface or corner ports to seal them

Cured Hydra Stop 300

Hydra Stop 300 cured foam expands up to 30x its initial volume. This fills the crack in your foundation and stops the water leaks.
