A single component, solvent free, very low viscosity, hydrophobic polyurethane water cut-off grout. . This product is specifically engineered for use in concrete, water bearing structures, or sandy environments to stop gushing water or water seepage including cracks in concrete where the structure is not subject to movement. It is formulated to react with water to form a rigid polyurethane closed cell foam that molds to substrate and stabilize surrounding soils to help its load bearingcapabilities. Characteristics: – Very low viscosity (110 – 130 cps) – Rapid compressive strength gains – Resistant to biological attack – Pumped as a single component – Reacts with water to form a close-cell watertight foam – Up to 2900% expansion – Variable reaction (set) time with the use of an accelerator – Capable of closing gushing leaks to watertight Uses Include: – Sealing leaks and filling wide gaps in concrete such as box culverts – Sealing tunnels (subway, water, utility, etc.) – Seals manholes, sanitary and storm pipe structures – Curtain grouting below grade structures in parking decks, foundations, and basements – Permeation grouting for soil stabilization in roads, highways, seawalls, and retaining walls
