BORE-GROUT horizontal heat loop grout is a bentonite grout designed for use in grouting boreholes containing horizontally installed ground source heat loops or where a grout is required to be placed around a horizontally installed product line. BORE-GROUT horizontal heat loop grout is designed to be mixed and pumped, neat, with standard horizontal directional drilling (HDD) rig equipment.
Silica sand may be added to BORE-GROUT horizontal heat loop grout to increase the thermal conductivity up to 1.2 Btu/hr·ft·°F (2.08 watts/m·°C). Sand-enhanced BORE-GROUT horizontal heat loop grout systems will require dedicated grouting equipment for mixing and placement.
