Thermal Resistivity Testing for Underground Power Projects
Effective heat dissipation is a critical factor in buried electrical systems’ design and long-term performance. At Atlantic Testing Laboratories (ATL), we offer advanced Thermal Resistivity Testing services that support underground power transmission projects’ planning, installation, and quality control. Our testing solutions help engineers make informed decisions about cable placement, backfill selection, and thermal performance across a variety of soil and material types.
ATL uses ASTM D5334 and IEEE 442 testing procedures to conduct precise thermal conductivity assessments for in-situ and laboratory-prepared samples. Our services are tailored to meet both the initial design requirements and ongoing quality assurance needs during construction. By accurately measuring how materials dissipate heat, we help prevent overheating, improve system efficiency, and extend the operational lifespan of underground electrical infrastructure.
Field and Laboratory Thermal Resistivity Testing Capabilities
ATL’s Thermal Resistivity Testing services are available in the field using portable, standards-compliant equipment that directly tests native soils and backfill materials. Our experienced field technicians can obtain samples using our in-house geotechnical drilling and sampling equipment, including Geoprobe™, barge, ATV, and truck-mounted drill rigs. Excavation capabilities are also available when needed.
Our accredited laboratories also provide thermal resistivity testing on remolded or intact samples of rock, soil, concrete, and fluidized thermal backfill (FTB). A key feature of our laboratory testing is the generation of thermal dry-out curves, illustrating the relationship between moisture content and thermal resistivity. Unlike empirically derived curves, ATL uses measured thermal and moisture data points to produce highly accurate, project-specific results.
Our Comprehensive Thermal Resistivity Testing Services Include:
- ASTM D5334 and IEEE 442 compliant thermal resistivity testing
- Development of thermal dry-out curves with measured data
- Testing of soil, rock, concrete, and fluidized thermal backfill
- Remolding of samples to preserve the structure and ensure accuracy
- Related geotechnical testing: Atterberg limits, proctors, electrical resistivity, and more
