Soil Resistivity And Conductivity

Soil Resistivity And Conductivity​ Services

Land Science provides a range of thermal resistivity and electrical conductivity testing of soil and rock cores in the field and laboratory. Example applications include cabling and pipeline projects such as onshore renewables, EV charging stations and transmission projects. Electrical conductivity testing can also be used for a variety of other applications including geotechnical, archaeological, and environmental.

Thermal Resistivity (TR)

A long thin needle is inserted into a test sample and a constant electrical current delivered; the resulting rise in temperature and the change in conductivity of the sample is recorded over a defined range. Tests can be conducted in-situ on soil and backfill materials in field conditions, and samples can be collected for laboratory analysis at various moisture contents.

  • Testing to ASTM D5334-14 and IEEE Std 442.
  • Field testing on soil and backfill at natural moisture content.
  • Laboratory 6-point dry-out curve.
  • Laboratory testing at specified moisture content.

  • Electrical Conductivity

    We operate a Syscal Junior, which is an all-purpose resistivity and induced polarisation sounding and profiling system for environmental applications and is perfect for Wenner sounding arrays. The equipment is suitable for most near surface geophysical applications, such as soil and bedrock mapping, water and pollution monitoring, underground structures.

  • Wenner 4 Pole resistivity.
  • Cathodic Protection and grounding assessment.
  • Geotechnical, archaeological, and environmental applications.
