MSEC Geothermal Conductivity Test

48 hour Geothermal Conductivity Test run per G.R.T.I. specifications. Data downloaded within 1 working day from completion of test. Does not include drilling, grouting materials. clean up, or utility location. Drillers log required within 2 working days of completion of the bore.

Full test to include the following materials, drilling, and labor);

1. Utility marking by JULIE

2. Bore up to 300 foot verticle bore with a diameter of < 6 inches. Depths in excess of 300 feet are done on a per foot basis.

3. Install HDPE u-bend geothermal loop up to 610 feet at 1 inch in diameter.

4. Grout to 1.0 conductivity using a mix of one part Thermal Grout Lite with five parts Badger geothermal silica sand.

5. Allow installed loop to adjust back to pre-existing temperature by waiting seven days before the test begins. (Heat is created by the drilling process.)

6. Attach pump, heaters, and GRTI data logger to the loop to record the estimated average heat capacity (Btu/cubic ft degrees F), thermal conductivity (Btu/hr-ft-degrees F.), and estimated thermal diffusivity (square ft/day).

7. Run test uninterupted for 48 hours.

8. Time to complete the analysis is approximatley two weeks after the field test is complete.

9. MSEC presents written report.

Spoils from the drilling are left on site, but clean up of bags, pallets, and all other construction debris is included.

This test loop can be incorperated for use into the loop field.
