BH20 is GeoPro’s conventional bentonite grout designed for use in applications where thermal conductivity is not of primary concern. Mixed as a 20% - 25% solids grout, BH20 sets into a semi-rigid plug well suited for sealing well casings, decommissioning abandoned wells and for geothermal heating and cooling systems where low thermal conductivity ranges in the bore annulus are acceptable. BH20 is not intended to hold silica sand in suspension to form a thermal grout.
BH20 is a stand-alone product requiring only potable water for mixing. BH20 does not require any polymers or additives and will not flash hydrate. The unique chemistry of BH20 decreases the amount and variety of materials required on site while reducing mix times and eliminating the need for on-site chemistry experiments.
BENEFITS

- Workable for 20 minutes when mixed with potable water at 50°F to 80°F.
- Permeability independently confirmed by third party laboratory
according to ASTM D 5084.
- Thermal conductivity independently confirmed by third party
laboratory according to ASTM D 5334.
- NSF/ANSI Standard 60 Certified to not contribute contaminants to drinking water that could cause adverse health effects.
SHIPPING INFO
All GeoPro grouts are shipped on heat shrunk 54 bag pallets. The number of pallets per truck may vary by carrier but is typically 17 for a total of 918 bags of grout per truckload.
NOTE: Heat shrinking is not meant as a water proofing measure, pallets should not be left exposed to the elements.
