Moisture/Density Relationship (Proctor)
Geotherm performs both modified and standard Proctor compaction tests per ASTM D1557 and D698 for soils and backfills.
Grain Size Distribution (Sieve Analysis)
Geotherm performs grain size distribution testing per ASTM D6913 for soils and granular material
Mix Designs
Geotherm can assist in the formulation of Concrete, FTB, Grout or Granular Backfills to meet the project thermal and mechanical requirements.
Heat of Hydration Testing
Geotherm performs Heat of Hydration tests on Concrete, FTB, Grout utilizing ASTM C1753
Route Thermal Surveys
A thermal survey of the proposed cable route is essential to evaluate the thermal and geotechnical properties of the subsurface or sub bottom soils. This includes the measurement of ambient temperature and in-situ thermal resistivity at select locations and depths. Industry standard soil boring/sampling procedures are followed in accordance with the ASTM. This is the first step in a cable system design from Ampacity (cable rating) viewpoint.
Through our experience and expertise, using the state-of-the-art test equipment (Thermal Property Analyzer-TPATM) and accessories (custom-built thermal probes) we provide these services for underground as well as submarine power cable routes.
