Standard Grout BH20- Brochure

BH20 is GeoPro’s conventional, non-thermally enhanced grout designed for use in bore hole sealing applications and geothermal applications where a thermal conductivity value of no more than 0.42 Btu/hr-ft-°F is required. 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 GSHP 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.HOW TO MIX PUMPINGFill conventional paddle mixer with required volume of Fresh Water (according to Mix Table).Start mixer and add a bag of BH20.Let mix for 1-2 minute(s). Pump using a positive displacement pump (piston pump is recommended) through a 1¼" nominal tremie pipe at a rate of 10 to 25 gallons per minute.Thermal Conductivity RangeMax Working TimeMix TableWARNING:If mixed with sand, damage to the pumps and tremie lines may occur.Mix water should be between 50°F and 80°F.

We maintain this status through rigorous product testing and the continuation of the industry-forming research we began nearly two decades ago.When mixed according to our guidelines, BH20 will meet or exceed design specifications without question. These results have been confirmed in thousands of tests performed in our labs on both field-mixed and lab-mixed samples. The permeability and thermal conductivity of BH20 are independently confirmed through third party laboratories.GeoPro stands behind each and every bag that we ship. GeoPro customers stay GeoPro customers not because we are the only product available, but because the products we sell work as promised and we are always there when you need us.BENEFITSQUALITYBH20 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.(877) 580-9348 or email sales@geoproinc.comDoes not flash hydrate.Requires no polymers or other chemical additives.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 partylaboratory according to ASTM D 5334.NSF/ANSI Standard 60 Certified to not contribute contaminants todrinking water that could cause adverse health effects.GeoPro is a leading expert in the geothermal heating and cooling industry. We paved the way for thermal grout and now we provide bentonite grouting products designed to improve the performance and decrease the initial cost of each and every GSHP system. To develop, distribute and sell bentonite-based thermal grouts that are the industry benchmarks for quality, consistency and pumpability.GEOPRO, INC.PRODUCT MISSIONTo further the understanding of the thermodynamic and physical characteristics of thermal grouts to guide focused improvement of our products for the geothermal heating and cooling industry.RESEARCH MISSIONTo eductate and provide quality services to help guide practitioners and policymakers, to ensure the continued success of the GSHP industry and the subsequent environmental benefits inherent to the wide-scale adoption of this verdant technology.SOCIAL MISSIONBH20 Grout is available in 50lb bags shipped on pallets of 54 bags each.www.geoproinc.comE2012-4
