Baroid Bore-Grout™

BORE-GROUT™ horizontal heat loop grout is a bentonite material designed for use in grouting boreholes containing horizontally installed ground source heat loops. BORE-GROUT horizontal heat loop grout is also used 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. Alternately, silica sand may be added to BORE-GROUT horizontal bentonite grout to increase the thermal conductivity, up to 1.2 BTU/hr·ft·°F (0.69 – 2.08 watts/m·°C). Sand-enhanced BORE-GROUT horizontal heat loop grout systems will require dedicated grouting equipment for mixing and placement. BORE-GROUT horizontal heat loop grout should only be used in the saturated zone.

Applications/Functions

    The use of BORE-GROUT horizontal heat loop grout promotes the following:
  • A thermally conductive grout medium with low permeability for sealing ground source heat loops installed in horizontal bores
  • A low permeability bentonite grout for sealing horizontal bores

Advantages

  • 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
  • NSF/ANSI Standard 60 Certified
