DAWSON-WAM delivers medium to large-scale steel sheet piling and combined steel tube and sheet pile solutions for a wide range of applications, including:
- Highways and railway retention
- Basement retaining walls
- Cofferdams for marine and inland works
- Harbour and quay walls
- Water retention and flood defence
- Temporary works and construction support
Market-Leading Equipment & Expertise
We own and operate the largest sheet piling rigs in the UK, making DAWSON-WAM the go-to piling contractor for major infrastructure projects. Our rigs are equipped with the latest ultra-high frequency vibro hammers, which significantly reduce the damaging low-frequency vibrations typically associated with lesser sheet piling systems, allowing safe working near sensitive structures.
Cased CFA Pre-Auger Capability
As the largest Cased CFA piling specialist in the UK and Ireland, DAWSON-WAM integrates Cased CFA pre-augering into sheet piling works. This allows us to install sheet piles to significant depths in mudstones, siltstones, and sandstone, while:
- Eliminating flighting risk for bore stability
- Boring through obstructions, mass concrete, and medium-strong rock
- Maintaining verticality and precision for secure sheet pile installation
Our next-generation quick docking system enables us to switch between pre-auger and vibro attachments in minutes instead of hours, maximising productivity and minimising downtime.

Pioneering Sustainability – First-Ever Reuse of Sheet Piles in a Permanent Structure for National Highways
In a UK industry first, DAWSON-WAM successfully reused sheet piles in a permanent structure for a National Highways project – a significant departure from standard practice where permanent works typically require new steel.
This innovative approach delivered:
- Huge carbon savings by avoiding the production of new steel
- Significant cost reductions for the client
- A proven, repeatable, and scalable method that can be applied to future infrastructure projects
This milestone demonstrates DAWSON-WAM’s commitment to sustainable engineering solutions and our ability to challenge conventional methods in pursuit of better environmental and economic outcomes.
Temporary & Permanent Support Systems
We provide full design and installation of both temporary and permanent sheet pile support systems, including:
- Temporary waling beams, anchors, and props for construction phases
- Permanent tie bar and anchor systems for harbour, quay wall, and waterway applications
