Why test with SRGPL
One laboratory for soil, rock, aggregate, concrete and water
Mechanical and chemical tests under one roof, so samples from one site do not travel between labs.
Advanced rock testing
From UCS and point load to triaxial, slake durability and Cerchar abrasiveness, the parameters needed for tunnels, deep foundations and rock cuts.
Accredited results
NABL accredited testing vide Certificate No. TC-12577 (ISO/IEC 17025:2017) for tests in our scope of accreditation, with reports that stand up in client and authority reviews.
Linked to the field
Our own drilling crews collect and transport samples, which keeps undisturbed samples undisturbed.
Often combined with Laboratory Testing
Geotechnical InvestigationOnshore and offshore subsurface investigation: boreholes up to 300 m, sampling, in-situ tests and design parameters.
Geotextile TestingGeosynthetics, rubber and metal testing: geotextile, geogrid, geocell and geostrap tests, barbed wire and rubber hardness.
Rubber & Barbed Wire TestingTensile strength, hardness, compression set and tear resistance of rubber, and strength testing of barbed wire.
Non-Destructive Testing (NDT)Pile integrity, high strain dynamic load test, CHSL, rebound hammer, UPV, half-cell potential and core testing.
