SUPER-CRETE™ Polygrout GS 500

Polygrout 500 is a hydrophobic grout based on polyurethane. Upon contact with water, Polygrout 500 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.
