Thermally Enhanced Grout

Barotherm is a bentonite material de-signed for use in a two-part system with sand. This thermally enhanced grout from Baroid Industrial Drilling Products is engineered to provide efficient heat transfer, to create a low permeability seal and to produce no heat of hydration. Its thermal conductivity values range between 0.4 Btu/hr/ft./ degrees F and 1.0 Btu/hr/ft./ degrees F. NSF/ANSI Standard 60-certified, Barotherm is used to seal or grout water well annular spaces and ground source heat loops.
