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.
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 testing is a geophysical method used to measure the electrical resistivity of the subsurface. It involves four electrodes placed in a straight line with equal spacing between them. The outer electrodes (current electrodes) inject a current into the ground, while the inner electrodes (potential electrodes) measure the resulting voltage drop.
By varying the spacing between electrodes, different depths of investigation can be achieved, allowing for a vertical electrical sounding of the subsurface. This method is particularly effective for mapping changes in subsurface resistivity, which can indicate variations in geological formations, groundwater levels, or the presence of contaminants.
Wenner 4-pole testing provides valuable data for geological surveys, environmental assessments, and engineering projects, helping to understand subsurface conditions without the need for invasive methods. It is of particular relevance to cabling and electrical infrastructure projects where earthing and cathodic protection is a consideration.
Thermal resistivity testing is a method used to assess the thermal properties of soils, which is crucial for designing efficient underground electrical infrastructure. It involves measuring how well soil conducts heat, which directly impacts the performance and longevity of buried power cables and electrical equipment.
In electrical infrastructure projects, thermal resistivity testing helps:
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.
By accurately measuring thermal resistivity, engineers can make informed decisions to enhance the efficiency, reliability, and safety of electrical infrastructure installations.
