DESCRIPTION
Cetco Geothermal Grout is a specially blended high solids bentonite that can be mixed with sand in a two-part thermally conductive grouting material to improve the performance of ground source heat loop applications. Cetco Geothermal Grout is an easy pumping grout that has been carefully developed to efficiently suspend solids (silica sand) for enhanced thermal conductivity. It can be mixed to meet a range of thermal conductivity (TC) from 0.40 to 1.40 Btu/hr/ft/F. TC values can be measured with a variety of testing methods and values can vary widely based on the differing methodologies as well as the quality of the sand added. The table at the bottom of this page states values based on 2 different testing methods for comparison. Certified to NSF/ANSI Standard 60, Drinking Water Treatment Chemicals – Health Effects.
ADVANTAGES
Improves the efficiency and performance of ground source heat loop systems by matching the thermal conductivity of the surrounding soil and creating a permanent flexible seal to prevent aquifer contamination. Depending on site soil conditions, it can be mixed and adjusted to meet individual thermal conductivity requirements, improving the transfer of heat between the fluids circulated in the loop and the surrounding soil for optimum system performance.
MIXING AND APPLICATION
Place freshwater in a paddle-mixing tank of a commercial grout mixer. Start the grout mixer paddle, and add one 50-lb bag to the water. Mix for about 1 minute. Add silica sand at a steady rate (1 to 2 minutes), and continue mixing for about 2 minutes to obtain a consistent mixture. Pump with a positive displacement piston pump through a tremie pipe at a rate of 5 to 15 gallons per minute.
