We specialise in a wide range of field testing and investigation activities to understand soil and rock conditions accurately, including:

✅ Exploratory borehole drilling through soil and rock up to 150 m depth using our fleet of 50+ mechanised and hydraulic drilling rigs

✅ Soil drilling with Auto-SPT and undisturbed sampling using borehole sizes of 75 mm, 100 mm, 125 mm, and 150 mm diameter, up to 300 m depth

✅ Standard Penetration Test (SPT) using automatic trip hammer system

✅ SPT energy measurement using PDI-manufactured SPT analyzer

✅ Undisturbed soil sampling using Shelby tubes, Mazier samplers, and piston samplers

✅ Trial pits for visual examination of shallow soil layers

✅ Static Cone Penetration Test (SCPT) using mechanical cone

✅ Electric Cone Penetration Test (eCPTu) with pore pressure measurement using Geomil (Netherlands) piezocone

✅ Dynamic Cone Penetration Test (DCPT / DCP) including TRL method

✅ Field California Bearing Ratio (CBR) test for pavement and subgrade evaluation

✅ Single and Double Packer Field Permeability Tests

✅ In-situ soil and rock permeability tests to assess groundwater flow

✅ Full-scale pump-out tests for dewatering system design

✅ Pressuremeter Test (PMT) using Menard pressuremeter equipment

✅ Static and cyclic Plate Load Tests (PLT)

✅ Footing load tests using customized load frame arrangement

✅ Field Vane Shear Test (VST) for in-situ characterization of soft clays
