Polyurethane grouting is made of PU mixed with accelerators grouted at high pressure in the concrete structures. It is effective in cutting off gushing water of high pressure and velocity. When used with uniform injection packers, the grout materials react with water/moisture and expand to form a tough, closed rubber that remains unaffected by corrosive environment. This is most effective for water retaining structures.
