Multiurethanes Rigid Grout is used for void filling applications beneath concrete slabs. Rigid Grout is a two component polyurethane grout that produces a strong, hard foam.  The low viscosity of this material facilitates injection.  The reaction results in an expansion of about 1000% of the original mix volume.

Multiurethanes Rigid Grout is a cost effective solution to fill voids beneath concrete slabs.
