What We Do
Specialist Ground
Investigation Services
From cable percussive drilling to UXO borehole clearance — the complete range of geotechnical services, delivered safely and accurately anywhere in the UK.
01
Cable Percussive Drilling
The UK's most common site investigation method. Depths to 80m and beyond, diameters 150–300mm.
02
Rotary Drilling
Deep borehole drilling to 160m and beyond. Rock core recovery and deep geotechnical investigations.
03
Cut Down Cable Percussive
Cable percussive drilling for low headroom and restricted access sites. Same quality, smaller footprint.
04
Geothermal Drilling
Deep borehole construction for ground source heat pump systems and district heating schemes.
05
Window Sampling & Dynamic Probing
Tracked percussive rigs for contaminated land and geotechnical investigations. To 10m depth.
06
Ground Penetrating Radar
Non-destructive subsurface imaging. Mandatory where non-metallic services may be present.
07
Trial & Hand Pitting
Visual ground investigation to 4.5m. CBR and plate bearing tests carried out in the pit.
08
CBR & Plate Bearing Testing
The data behind every road, pavement and foundation design. Results interpreted and explained.
09
Coring
25–300mm diameter through concrete, brick and stone. Clean, precise holes in confined spaces.
10
Soakaway Testing
Infiltration testing to BRE Digest 365 for soakaway design and planning applications.
11
UXO Borehole Clearance
Pre-drilling magnetometer clearance by UXO specialists where buried ordnance risk has been identified.

Questions
We offer a full range of geotechnical site investigation services including cable percussive drilling, rotary drilling, cut down cable percussive drilling, geothermal drilling, window sampling and dynamic probing, ground penetrating radar (GPR), trial and hand pitting, CBR and plate bearing testing, soakaway testing, coring, and UXO borehole clearance — all available across the UK.
Cable percussive drilling typically reaches up to 80m. Greater depths are achievable using rotary drilling — we have drilled to 160m and beyond on geothermal projects.
Yes. Despite being based in Wigan, Greater Manchester, we provide geotechnical site investigation and environmental drilling services across the entire United Kingdom, remaining fully competitive on pricing regardless of your location.
Window sampling is used for the investigation of contaminated land, geotechnical investigations, and the installation of ground gas and groundwater monitoring wells. Depths of up to 10m below ground level can be achieved depending on soil type.
Yes. All lead drillers hold NVQ Level 2 in Land Drilling and all site staff carry CSCS cards. We are accredited with City and Guilds.
GPR uses electromagnetic radiation pulses to image the subsurface. It is mandatory in the majority of mapping surveys where non-metallic services may be present, allowing engineers to identify buried utilities, voids, and other subsurface features without excavation.
A California Bearing Ratio (CBR) test assesses the strength of sub-grade soils for the design of roads, pavements, and concrete slab foundations. If you are planning a road, car park, or hardstanding you will likely need one. We carry out CBR and plate bearing tests across the UK and can help you interpret the results.
