Professional Site Investigations for Ground and Environmental Risk Assessment
Helping You Understand What's Beneath the Surface
Every successful construction project starts with a clear understanding of the ground it is built on. Our experienced engineers provide comprehensive Site Investigation Services that help developers, architects, contractors, and property owners identify potential ground-related challenges before they become costly problems.
Whether you're planning a new development, extension, infrastructure project, or property purchase, we deliver accurate data and practical recommendations to support confident decision-making from the outset.
Reduce Risk. Save Time. Control Costs.
Unexpected ground conditions can lead to project delays, design changes, increased costs, and compliance issues. Our detailed Ground Investigations help identify geotechnical and geo-environmental risks early, allowing your team to plan effectively and avoid unnecessary surprises during construction.
We combine technical expertise with clear communication, ensuring complex findings are translated into practical insights that support your project goals.
How you benefit from a good site investigation
While the site investigation is not the most high-profile part of your construction project, its value to your project's successful outcome should not be underestimated. A thorough combined geotechnical and geo-environmental investigation at the outset of your project will:
- Allow you to understand the in-ground risks you face in good time
- Give you peace of mind that a costly issue will not be uncovered later in the project
- Help your project run to time and budget
- Provide you with an audit trail that demonstrates robust due diligence was undertaken
Our site investigation services
There is no set template to a site investigation; every site is unique and every client has their own requirements depending on where they are in their process. Our services reflect this.
Whenever possible, we seek to combine investigations to save clients both time and money. On-site we can employ a range of techniques including:
- Trial pitting
- Rotary percussive/open hole drilling works
- Cable percussive drilling works
- Cone penetration testing
- Windowless borehold drilling
- CBRs
- Infiltration testing
- 3D Ground Modelling
As well as the technical quality of the work that our in-ground specialists will undertake on your site, we have a robust off-site infrastructure with which to analyse our samples and draw the correct conclusions. Moreover, our many years of experience mean we are used to working on all site sizes and conditions. We always put health and safety at the forefront of our thinking, working to all relevant regulations and applicable standards.

Case Study – Ground Investigation & Remedial Strategy Design
