GEOTHERMAL GROUT is a specially blended high solids bentonite that can be mixed with CETCO TC BOOSTER, sand, or both in a two-part thermally conductive grouting material to improve the performance of ground source heat loop applications. GEOTHERMAL GROUT is an easy pumping grout that has been carefully developed to efficiently suspend solids (CETCO TC BOOSTER or silica sand) for enhanced thermal conductivity. GEOTHERMAL GROUT can be mixed to meet a range of thermal conductivity (TC) from 0.4 to 1.9 Btu/hr/ft/F (0.7 – 3.3 W/ mK). NSF/ANSI/CAN Standard 60 Certified.
