GeoPro - Thermal Grout Lite Brochure

Thermal Grout Lite is GeoPro’s original thermal grout base specifically designed to optimize the performance of ground heat exchangers for the geothermal heating and cooling industry.A unique blend of bentonite, Thermal Grout Lite is designed for use with high quality silica sand to achieve thermal conductivities from 0.45 to 1.00 Btu/hr ft °F. When using a combination of high quality silica sand and GeoPro’s PowerTEC, TG Lite will achieve thermal conductivities up to 1.40 Btu/hr ft °F. For PowerTEC mix ratios call (877) 580-9348.HOW TO MIX PUMPINGWARNING:Fill conventional paddle mixer with required volume of Fresh Water (according to Mix Table).Start mixer and add a bag of TG Lite. Let mix for 1 minute.Slowly add required weight of Silica Compound (should take 1-2 minutes).Once all Silica Compound is added, continue mixing for an additional 1-2 minutes.Pump using a positive displacement pump (piston pump is recommended) through a 1¼" nominal tremie pipe at a rate of 5 to 15 gallons per minute.Adding more than the specified amount of water may make this product more difficult to pump.Mix water should be between 50°F and 80°F.Mix Table(Btu / hr-ft-°F) (lb) (gal) (gal) (lb/gal) (by weight)Target Thermal ConductivitySilica Compound Fresh Water Yield Density % Solids0.450.570.690.790.881.0005010015020025014.014.515.516.517.518.517.019.623.026.229.332.69.8111.2712.1412.8913.5113.9430.045.353.759.263.166.0Thermal conductivity values are based on using a silica compound supplied by GeoPro, Inc.Target Thermal Conductivity RangeMax Working Time30min (Btu/hr-ft-°F)0.45 0.79 1.00 1.40TG Lite with Silica Sand Only TG Lite with PowerTEC OnlyTG Lite with Silica Sand & PowerTECFor thermal conductivities greater than 1.40, use TG Select.GeoPro products are the benchmarks for quality, consistency and pumpability within the thermal grout market. 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 with approved silica sands, TG Lite 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 TG Lite 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.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. GeoPro will provide free thermal conductivity analysis to any customer. Simply request a testing kit and we will send you three sample containers to be used on multiple batches throughout the duration of your installation. Fill a container and return it to us in the provided box.Our blind testing procedure is designed so that we don’t know what thermal conductivity value you are targeting. We perform our analysis and send back a report of the thermal conductivity your mix actually achieved.Test results are guaranteed within 3 business days of delivery to our testing facility. If your targeted thermal conductivity is not met, our expert staff will help you to identify the reason and present you with a solution to keep your project on track.GEOPRO, INC.TESTINGBENEFITSQUALITYTG Lite increases the efficiency of ground heat exchangers allowing for shorter design lengths. As a result, TG Lite decreases work time and grout volume per bore so you can complete more projects per year with a substantial savings in material cost.As with all of GeoPro’s grouting products, Thermal Grout Lite is designed to minimize the variety of materials required on site while maximizing available working time. TG Lite does not require any polymers or additives and will not flash hydrate. Only potable water and silica sand are needed to meet performance specifications.TG Lite is available in 50lb bags shipped on pallets of 54 bags each. Approved silica sand availability varies based on location.(877) 580-9348 or email sales@geoproinc.com www.geoproinc.comDoes not flash hydrate.Requires no polymers or other chemical additives.Workable for 30 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.E2012-4
