Thermal Resistivity Measurement of Soil and Backfill Material

Powertech provides field and laboratory testing services to measure the thermal resistivity of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities.

As an organization built on knowledge and technical expertise, we provide only the most experienced geotechnical engineers to describe the thermal behavior of your soil. One of our largest customers is BC Hydro, a large electric utilities company in Canada. However, we also provide services to a number of global clients in the electric and gas industry.

Estimating thermal behavior of soil should be part of any cable design or any thermal storage facility design. It is the only way for you to receive a complete soil diagnostic that will allow you to determine the variations and/or characteristics of thermal dissipation that exist in the soil. This extremely valuable information helps you determine the correct cabling requirements, cable alignments, and if necessary, identify the suitable cable backfill material.

When using Powertech’s soil thermal resistivity services you can expect the following:

First Stage:

On-site thermal resistivity measurements.

Second Stage:

Laboratory thermal resistivity
measurements of a rock sample.
Laboratory thermal resistivity
measurements of a soil sample.
