CHEM-CRETE HPG551
Hydrophobic Polyurethane Grout


Chem-Crete HPG551 is a two-part (Part A & Part B) polyurethane injection material, when these two parts are reacted they produce a rigid, closed-cell foam. This product is used as an effective stabilizer in water-bearing soils and can lift sunken floors, slabs and roadways. Also it can be used to fill voids to prevent leaking of liquids like water into a closed space.

Both parts of Chem-Crete HPG551 do not contain any solvents or volatile materials. The low viscosity of these materials permits easy installation and injection of the product for maximum effectiveness. The reaction of Part A & Part B results in an expansion of about 10 times of the original mix volume to produce a 6 pound per cubic foot foam. The temperature of the materials when mixed and the temperature of the soil into which the material is introduced control the speed of the reaction.
