What's really below your plot?
Before foundation work begins, understanding subsurface conditions can save significant time, cost, and uncertainty during construction.
An ERT Survey (Electrical Resistivity Tomography) is an advanced geophysical investigation method used to identify rock depth, groundwater zones, weak soil pockets, cavities, and underground variations before excavation starts.
ERT surveys play an important role in soil testing, geotechnical investigation, foundation planning, and infrastructure development. The information helps engineers, architects, developers, and contractors make informed decisions based on actual ground conditions rather than assumptions.
At GTSM Testing Labs LLP, we provide NABL Accredited Soil Testing, Geotechnical Investigation, ERT Survey, Borehole Drilling, Foundation Investigation, Construction Material Testing, NDT Testing, and Structural Assessment services across Ahmedabad, Gujarat, and surrounding regions.
Because good construction starts with understanding the ground beneath it.
