ATL continues to support the building of a more resilient electrical grid by providing thermal resistivity testing for soil, concrete, grout, and fluidized thermal backfill in accordance with ASTM D5334 – Determination of Thermal Conductivity of Soil and Soft Rock by Thermal Needle Probe Procedure.

We are supporting renewable energy projects involving generation and transmission construction across the Northeastern US, and recently received samples for laboratory testing from projects in the mid-Atlantic and Central US, as well as large scale offshore wind projects in the Northeast.

ATL can provide thermal resistivity testing on samples shipped from anywhere in the US. For more information, read our Thermal Resistivity Testing paper or contact our service area expert, Royce Knowlton at 585-427-9020 or
