Cements & Grouts - Geothermal

Therm-Ex Grout is an engineered system for use as back fill 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 …

Grout-Well and Grout-Well DF are one step bentonite grouting materials designed to achieve low permeability seals in water wells, monitor wells, geotechnical borings, and heat pump holes. They achieve a range of solids contents, 17% to 20% solids by weight. Grout-Well DF’s granular nature reduces dusty conditions during mixing operations.
