Our geotechnical services team provides site investigation solutions that combine experienced geotechnical consultancy skills with state of the art contracting services and plant. With over 10 years’ experience we have developed high quality ground investigation, geophysical and topographic surveys across more than 100 renewable, grid, infrastructure and water related projects.
We deliver solutions within wider construction management teams, integrated with planning, design and constructions processes, ensuring that work is carried out efficiently and to the highest levels of health and safety.
Our experienced team of chartered engineers, geotechnical and civil engineers and geophysicists are supported by a professional drilling team well versed in a wide selection of drilling and sampling methods. We carry out conventional and bespoke ground investigations to Eurocode 7 standards throughout the UK, Republic of Ireland and internationally.
2.5GW of wind farm site investigation safely completed
We regularly complete site investigation in challenging and complex geologies for successful infrastructure design. Challenges include peat, chalk, artesian water, deep fluvial deposits, unexploded ordinance (UXO), mining, upland terrain, remote access, forestry, slope stability etc.

- Remote access ground investigation
- Input to detailed civil and structural design
- Construction phase formation checks and problems solving
Groundwater and water wells
We install agricultural, commercial and domestic water wells throughout the UK. Our hydrogeologists are available to determine whether groundwater abstraction is feasible, identify the aquifer and best place to drill.
Using our experience we will give you an idea of the regional success and typical abstraction rates / quality.
Our consulting engineers will design your well to ensure correct, efficient function, adequate surface protection and liaise with the authorities to ensure the correct notifications and licences.
We have a selection of modern low ground pressure drilling plant handling water well projects up to 300mm diameter. We offer the following services:
- Water well drilling and installation
- Pump installation and commissioning
- Water well rehabilitation and inspection
- Water filtration and chemical testing
- Groundwater exploration and prospecting
- Aquifer mapping and investigation
- Geophysical surveying
- Pump testing yield and water sampling
Geothermal & ground source heat pumps
- Ground source heat pump (GSHP) drilling and loop installation
- Thermal response testing and analysis
- Residential and commercial scale systems
- Project due diligence and technical advisor services
