Geophysical Tests
MASW, ReMi, seismic refraction, cross-hole, GPR, electrical resistivity and borehole logging in any terrain.
Geophysical Tests at SRGPL
Our geotechnical engineers, geologists and geophysicists carry out geophysical tests with precision in any terrain: rainy, muddy or dry. Tests recently carried out in Himachal Pradesh at temperatures as low as 4 °C show the commitment of our experts.
Surface and borehole geophysics give a continuous picture of the ground between boreholes, which reduces risk on large linear projects, foundations and tunnels.

Where geophysics helps
Between the boreholes
Surface surveys map the ground continuously between boreholes, which reduces risk on long alignments such as rail, highways and pipelines.
Seismic design inputs
Shear wave velocity profiles from MASW, cross-hole and down-hole tests feed site classification and dynamic analysis.
Rock and water
Resistivity, TEM and borehole logging locate weathered zones, cavities, fractures and groundwater.
Any terrain
Our team works in rain, mud, dry ground and cold, including tests in Himachal Pradesh at 4 °C.
