Geotechnical Investigation (Onshore & Offshore)
Onshore and offshore subsurface investigation: boreholes up to 300 m, sampling, in-situ tests and design parameters.
Geotechnical Investigation at SRGPL
We specialise in geotechnical investigation for both onshore and offshore projects. It sits at the core of our services and is carried out by a team of seasoned technocrats: geotechnical engineers and geologists trained to check the minute details and deliver quality and precision.
From trial pits to deep boreholes drilled from jack-up barges, we collect the subsurface data that foundation design depends on and turn it into clear, usable geotechnical reports.
We specialise in carrying out the following
18 items- 01Soil drilling with Auto-SPT and undisturbed sampling with borehole sizes of 75 mm, 100 mm, 125 mm and 150 mm diameter up to 300 m depth
- 02Rock core drilling for open and underground mining of Ex, Ax, Bx, Nx, Hx, Px, AQ, BQ, NQ, HQ, PQ size
- 03Trial Pits

What the investigation gives you
Soil and rock profile
Borehole logs showing each stratum, groundwater level and rock quality, so the foundation type and founding level can be fixed with confidence.
Design parameters
Strength, compressibility and permeability values from field and NABL accredited (TC-12577) laboratory tests, ready for pile, raft and slope design.
Onshore and offshore
The same crews and quality system on land and over water, including jack-up barge investigation for sea links, ports and marine structures.
A report you can build on
A geotechnical report with recommendations, reviewed by qualified geotechnical engineers before it is issued.
