Concrete often cracks. It is inevitably recognized and experienced. Concrete construction requires joints. These joints cause very serious problems of water leakage.
Estofoam PU is a water-reactive grout specifically designed for injection into leaking concrete, masonry or brickworks 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.
Estofoam PU forms an excellent barrier against water seepage caused by hydroscopic pressure. It has good chemical resistance and it is non-toxic once set. By restraining the natural expansion created by this reaction, a strong closed-cell semi-rigid foam is formed, providing a permanent barrier to the ingress of water.
