Geological & Geotechnical Explorations

Conducting surface and subsurface geological and geotechnical investigations for infrastructure siting, slope stability assessment and foundation design- combining engineering geology mapping, borehole drilling, in-situ testing and laboratory analysis to characterise ground conditions for informed engineering decisions in complex mountain geology.

Geological mapping

Conducting systematic engineering geological mapping of project areas, dam sites and infrastructure corridors. Characterising rock mass quality, structural geology, fault zones, weathering profiles and mass movement features to inform geotechnical design, slope treatment and construction planning.

Core drilling & in-situ tests

Executing rotary core drilling programmes and in-situ testing (SPT, CPT, pressuremeter, packer tests) for foundation assessment, dam site investigation and slope stability analysis- recovering representative core samples for laboratory testing and providing continuous subsurface ground condition profiles.

Geophysical investigations

Applying non-invasive geophysical methods — electrical resistivity tomography (ERT), seismic refraction, MASW and ground-penetrating radar to characterise subsurface stratigraphy, groundwater depth, void detection and rock mass quality for infrastructure siting and geotechnical design in difficult access terrain.
