More About Us

Much of what we do happens below the surface, hidden from view, but it provides the essential foundations on which ambitious projects depend.

We understand that every successful project begins with a strong foundation, both in the ground and in the relationships we build. For more than 50 years, our team has delivered trusted, innovative ground-engineering solutions that give clients confidence from the outset. From earthworks and ground beams to marine piling and specialist civil engineering, we reduce risk by handing over sites fully prepared for construction. Our commitment to safety, quality and sustainability ensures that every project is completed with integrity and precision. We take pride in the lasting value we create, because everything we do is built on strength.

Piling

Piling is the ideal solution when ground conditions are weak or additional structural loads need support. Our piling systems provide a strong, reliable foundation by transferring loads safely into deeper, more stable soils or rock. This ensures long-term structural integrity for projects of any scale.

Retaining Walls

Retaining walls are essential for supporting changes in ground level and maintaining stability on slopes, roadworks, and developments. We design and construct robust retaining systems that resist earth pressures, protect surrounding land, and deliver safe, durable ground support.

Ground Improvement

Ground improvement strengthens weak or unstable soil, making it suitable for safe and efficient construction. Using proven techniques such as compaction, stabilisation, and reinforcement, we enhance load-bearing capacity and reduce risk, helping projects move forward with confidence.

Grouting

Grouting is a highly effective method for strengthening ground, reducing settlement, and controlling water flow. By injecting specialist grout materials into soil or rock, we fill voids, improve stability, and provide long-lasting ground support for complex site conditions.

Support & Anchoring

Support and anchoring systems are critical for stabilising excavations, slopes, and retaining structures. Our solutions reinforce the ground, prevent movement and deliver strength and support for challenging environments.

Specialist Works

Our expert team delivers civil engineering and environmental services, including invasive species management, coastal protection, slope stability solutions, and professional surveys and inspections, providing clients with flexible, tailored support.
