THERMAL GROUT LITE
TG Lite is GeoPro’s original bentonite grouting product for use in thermally-enhanced applications. It can be used to achieve thermal conductivity values up to 1.20 with PowerTEC (or up to 1.0 with silica sand).
TG Lite is the benchmark for quality, consistency and pumpability within the thermal grout market. When compared to TG Select, TG Lite is the most cost-effective way to reach the thermal conductivity values in the range provided. The majority of ground heat exchanger designs call for thermal conductivity values below 1.20 , making TG Lite the most predominant grouting product in the geothermal heat pump industry today.
As with all of GeoPro's grouting products, TG Lite provides superior groundwater protection and environmental sealing capabilities.
BENEFITS
When mixed according to our specifications, TG Lite:
- Does not flash hydrate.
- Does not require thorough testing of mix water chemistry prior to use.
- Does not require the use of polymers, soda ash or other chemicals for proper handling.
- Provides more working time in the field compared to the leading alternative, which leads to less frequent problems with system plugging and shutdown.
- Complies with IGSHPAs Closed-Loop Design and Installation Standards.
- Provides an environmental seal with a measured permeability values less than 1x10-7 cm/s (tested according to ASTM D-5084).
- Provides a wide range of thermal conductivity values to choose from (tested according to ASTM D-5334).
- Complies with NSF/ANSI Standard 60 requirements for purity and suitability for contact with drinking water.
TG Lite is packaged in 50lb bags with 54 bags per heat shrunk pallet. Properties and associated certifications are independently verified by a third party laboratory. Copies of independent test reports are available upon request.
QUALITY ASSURANCE
Grout sample thermal conductivity testing is an important component of thermal grout commissioning and quality assurance efforts for every installation. GeoPro, Inc. provides free thermal conductivity testing for any customer who chooses to take advantage of the service.
CG PLUS
CG Plus is a set of field-mixed grout recipes that consist of TG Lite, PowerTEC and Type II Portland Cement. These recipes can be used to achieve thermal conductivity values up to 1.20 .
When mixed according to our specifications, CG Plus will provide an environmental seal, even in harsh saltwater environments. Resistance to degradation due to salt water intrusion makes CG Plus the preferred grouting choice in coastal regions. CG Plus can also be used where cementitious grouting products are required by local code.
BENEFITS
When mixed according to our specifications, CG Plus:
- Does not flash hydrate.
- Does not require thorough testing of mix water chemistry prior to use.
- Does not require the use of polymers, soda ash or other chemicals for proper handling.
- Provides salt water resistance for concentrations up to 35,000 ppm
- Increases grout pH to 10 or higher for corrosion protection with copper-piping (direct-exchange applications).
- Complies with IGSHPAs Closed-Loop Design and Installation Standards.
- Provides an environmental seal with a measured permeability values less than 1x10-7 cm/s (tested according to ASTM D-5084).
- Provides a wide range of thermal conductivity values to choose from (tested according to ASTM D-5334).
- Complies with NSF/ANSI Standard 60 requirements for purity and suitability for contact with drinking water.
TG Lite is packaged in 50lb bags with 54 bags per heat shrunk pallet. PowerTEC is packaged in 32lb bags with 75 bags per heat shrunk pallet. Portland Cement is not supplied by GeoPro but for the purposes of our recipes is assumed to be packed in 47lb bags.
Properties and associated certifications are independently verified by a third party laboratory. Copies of independent test reports are available upon request.
QUALITY ASSURANCE
Grout sample thermal conductivity testing is an important component of thermal grout commissioning and quality assurance efforts for every installation. GeoPro, Inc. provides free thermal conductivity testing for any customer who chooses to take advantage of the service.
For salt water resistance, CG Plus recipes require Type II Portland Cement. These recipes are specifically designed to work in saline environments and in applications where cementitious grouting products are required by local code. If your project does not match these criteria, please contact GeoPro before choosing a CG Plus grout recipe.
