Soil Thermal Resistivity
Metro Testing + Engineering uses a transient-line heat source method for determining a soil’s physical properties according to its thermal characteristics. Soil thermal resistivity is used to calculate the safe thermal capacity of buried utility cables and pipes to maximize their service life according IEEE 442-03, ASTM D5334-08, and SSSA Part 4 Method 5.3. Soil thermal resistivity can also be used to select suitable backfill materials for new construction and as an investigative tool where signs of suspected cable failure are observed. Field thermal resistivity surveys are also available upon request.
- Subsurface investigation of new construction
- Selection of suitable backfill materials
- Determination of a soil’s physical properties such as thermal diffusivity, specific heat, thermal conductivity (heat transfer), thermal resistivity
