SmartCare PU Injection Grout Supply & apply with nozzle PU Injection (1K) is a hydrophobic grout based on polyurethane. Upon contact with water, it reacts to form a closed cell rubber-like foam while expanding its volume up to 27 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the pressure of injection, it reacts to a form a very dense material or foam.
