BAROTHERM GOLD thermally conductive grout is a bentonite material designed for use in grouting boreholes containing ground source heat loops, and related applications.

BAROTHERM GOLD thermally conductive grout when combined with silica sand or MAX-YIELD™ TCM at various concentrations yields a grout with thermal conductivity values ranging between 0.4 and 1.2 BTU/hr·ft·ºF (0.69 – 2.08 watts/m·°C).

  • A thermally conductive grout medium with low permeability for sealing ground source heat loops
  • May be used with or without thermally conductive products
  • May be enhanced with silica sand or MAX-YIELD TCM
  • NSF/ANSI/CAN Standard 60 certified
  • Promotes efficient heat transfer
  • Produces a uniform slurry for smooth pumping – No need to add extra water
  • Creates a low permeability seal
  • Develops a permanent, flexible seal to prevent commingling between aquifers
  • No heat of hydration
  • No Portland or aluminum cement added
  • No gypsum added
