Electrical Resistivity Survey is a geophysical method used to map underground conditions by measuring how the ground resists electrical current. In Malaysia, this method is widely used to detect groundwater, identify bedrock depth, and locate soft soil zones or voids.
It is a non-invasive and cost-effective tool for site investigation, especially for construction, slope assessment, landfill studies, and environmental monitoring.
At Geotechnica, we provide electrical resistivity services in Malaysia using modern equipment and expert interpretation helping engineers and planners make safer, data-driven decisions.
OUR SERVICES
01
Electrical resistivity is used in archaeology to detect buried features like walls, graves, and ancient structures without excavation.
02
Resistivity surveys help map underground layers, faults, and anomalies to understand ground conditions before construction or drilling.
03
Used to locate zones of mineralization by detecting resistivity contrasts in rock and soil related to ore bodies.
04
Electrical resistivity helps locate groundwater sources, aquifer depth, and water-bearing zones in both shallow and deep settings.
05
Used to assess soil contamination, leachate movement, and landfill boundaries for environmental monitoring and cleanup.
06
Resistivity surveys help assess slope stability by detecting water saturation, weak layers, and slip surfaces beneath slopes.

FAQ
An electrical resistivity survey is a geophysical method that measures how the ground resists electric current to map underground layers or features.
It is used for subsurface mapping, groundwater detection, bedrock profiling, contamination studies, and slope analysis without the need for drilling.
Yes, it is a non-invasive and cost-effective method that does not damage the site and is suitable for construction, environmental, and archaeological work.
When done correctly, it provides reliable results about subsurface conditions up to tens of meters deep—ideal for tropical soils and diverse terrains in Malaysia.
Yes, electrical resistivity is commonly used to locate groundwater zones, aquifers, and freshwater–saline water boundaries.
It is widely used in construction, mining, environmental consulting, agriculture, slope hazard assessment, and utility planning.
ERT (Electrical Resistivity Tomography) maps underground layers in 2D/3D, while a soil resistivity test usually checks surface soil resistance for grounding systems.
Depending on site size, it typically takes a few hours to a day for fieldwork, followed by 1–3 days for data processing and interpretation.
Yes, especially for large or sensitive projects, it helps identify soft soils, rock depth, or groundwater issues that affect foundation design.
Geotechnica offers expert interpretation, modern ERT equipment, and reliable geophysical services tailored for Malaysian ground conditions and project needs.
