SITE INVESTIGATION
Comprehensive geotechnical and geoenvironmental investigation services designed to support construction, design, and risk assessment.
Capabilities include:
-
Borehole drilling to all depths
-
Soil & rock sampling (disturbed and undisturbed)
-
In-situ testing (SPT, permeability)
-
Installation of monitoring wells
-
Groundwater and gas monitoring
-
Contaminated land investigations
-
Limited access, low headroom and basement works
Our team is trained to work safely on all site types, including restricted access, confined spaces, and complex urban settings.
Cable Percussive Drilling
A widely used method ideal for cohesive, granular, and mixed soil conditions. Suitable for deep boreholes and high-quality sample collection.
Why choose cable percussive?
-
Suitable for clays, silts, sands & soft rock
-
Depth capability typically up to 50m+
-
Disturbed & undisturbed sampling
-
In-situ testing: SPT, permeability, soakaway testing
-
Installation of piezometers & gas wells
-
Excellent for piling design, foundation assessment & groundwater studies
Electric, diesel, tracked, and compact rigs allow us to operate across all terrains.
