We offer a full range of specialist pipeline installation techniques to suit project conditions, including:

• Open cut excavation
• Directional drilling
• Pipe bursting
• Micro-tunnelling
• Pipe jacking
• Small and large-diameter pipe welding

This breadth of methods enables us to deliver safe, efficient, and cost-effective solutions in both urban and rural environments.

DAWSON-WAM also offers specialist sewer lining services to extend the operational life of existing sewer networks without the need for full excavation. Our trenchless rehabilitation techniques minimise disruption, reduce costs, and help meet environmental targets by lowering waste and carbon output.

We work with a range of lining methods, including:

• Cured-in-place pipe (CIPP) lining for minimal-intrusion repairs
• Slip lining for structural strengthening and leak prevention
• Patch lining for targeted defect repair
• UV-cured lining for rapid installation and curing

These techniques are suitable for sewer refurbishment, storm water system upgrades, and industrial drainage rehabilitation, ensuring long-lasting performance and regulatory compliance.

In addition to pipeline installation, DAWSON-WAM provides comprehensive manhole and chamber construction, as well as shaft sinking for pumping stations and tunnelling works. Our civil engineering teams are highly skilled in delivering complex projects, even in poor ground conditions and challenging environments.

We are recognised specialists in deep pipeline installation, offering a variety of temporary trench support systems, including:

• Traditional trench box and drag boxes
• Sheet piling
• Contiguous piled walls
• Secant piled walls

These engineered solutions ensure stability, worker safety, and compliance with all relevant UK regulations.

From local drainage schemes to national water infrastructure projects, our pipeline projects are delivered with the highest standards of quality, safety, and environmental stewardship.
