The SealGuard II is a highly reactive dual-component hydrophobic polyurethane water-stop system. It is used to repair leaks for manholes, slurry wall, basements, or anywhere underground.
When injected, the SealGuard II’s chemical components react and expand up to 20 times, creating a foam seal within the cracks. This process creates up to 300 degrees of heat and is installed at eye-level. The 141 check valve plays a critical role because it keeps the polyurethane in the tube - otherwise there is a risk this dangerous chemical could spew out similar to a shaken soda. In addition, because of the wide variety of body and O-ring materials, Smart Products has the ability to create material combinations that perform in some of the most demanding environments.
