A single component, 100% solids, flexible, low viscosity, injection resin for water stopage in concrete, masonry, and sandy soil structures even when strong seepages or gushing leaks are entountered. Its reaction with water results in the formation of a flexible polyurethane which forms a hydrophobic and chemically-resistant barrier. Characteristics: – Rapid water tight seal formation – Forms a hydrphobic and chemically resistant barrier – Remains flexible without further shrinking or swelling – 100% solids – Adapatable reaction time with the use of an accelerator – React s with water – Low viscosity Uses Include: – Concrete and masonry retaining walls – Sea-walls of various substrate – Box culverts – Tunnels – Pipe penetrations in concrete, masonry, and soil substrates – Concrete tanks – Concrete clarifiers
