Thermal Grout Lite

Thermal Grout Lite is a unique bentonite-based two-part, field mixed, high to very-high solids, grouting material that can mixed to meet a range of thermal conductivity’s from 0.45 to 1.00 Btu/hr ft °F. It has been specifically developed for closed-loop ground-coupled heat pump applications where thermal conductivity in the vertical bore column is critical to system performance. This product is certified by the National Sanitation Foundation International to ANSI/NSF Standard 60, Drinking Water Treatment Chemicals - Health Effects. Thermal Grout Lite contains no chemical polymers or organic matter.

Thermal Grout Select

Thermal Grout Select is a uniquebentonite-based two-part, field mixed, high to extreme-high solids grouting material that can mixed to meet a range of thermal conductivity's from 0.45 to 1.45 Btu/hr ft °F. It has been specifically developed for closed-loop ground-coupled heat pump applications where thermal conductivity in the vertical bore column is critical to system performance. This product is certified by the National Sanitation Foundation International to ANSI/NSF Satndard 60, Drinking Water Treatment Chemicals - Health Effects. Thermal Grout Select contains no chwmical polymers or organic matter.

Bentonite Plug 3/8" and 3/4" (Chip Bentonite)

Specially sized natural sodium bentonite. Industrial uses include seismic shot hole abandonment, water well abandonment, and well casing sealer. Will pour through standing water. Slow hydration time allows this product to be placed without bridging in deep bore holes.
