    Therm-Ex Grout™

    Therm-Ex Grout™ is an engineered system for use as backfill material in earth-coupled heat pump systems. Its elevated thermal conductivity and low permeability allow for excellent heat exchange while protecting groundwater supplies.

    Therm-Ex Grout™ should be pumped using a positive displacement pump capable of generating pressures in excess of 300 psi. Developed using high-swelling Wyoming Bentonite, this new generation of grouting material offers efficient installation of closed-loop geothermal heat pump systems.
