PU Grout

PU grout,is a water-reactive grout specifically designed for injection into leaking concrete, masonry or brickwork, to stop the flow of water.Commencement of the chemical reaction with water can be adjusted by the addition of a variable quantity of catalyst.

PU grout forms an excellent barrier against water seepage caused by hydroscopic pressure, has good chemical resistance and is non-toxic once set. By restraining the natural expansion created by this reaction, a strong closed-cell rigid foam is formed, providing a permanent barrier to the ingress of water.
