Our Civils & Construction Diving Capabilities

As a leading civils diving contractor UK, we deliver a full range of underwater construction and marine infrastructure services. We provide comprehensive support across both inshore and offshore construction projects. In addition, we tailor each solution to meet site-specific engineering challenges.

Desilting and Dredging 👉  Case Study

We remove sediment build-up quickly using airlifting and dredge pumping systems. Consequently, we restore flow, eliminate blockages, and improve structural performance.

Underwater Welding and Burning👉 More Info

Our coded divers carry out structural welding and cutting using IMCA-compliant procedures. Therefore, we can complete critical repairs and modifications without delaying your programme.

Concrete Placement and Grouting

As part of our marine construction diving services, we install underwater formwork and deliver tremie concrete pours and grout bags for scour protection and structural reinforcement. This ensures long-term integrity of your assets.

Pile Inspection and Repair👉 More Info

We inspect, clean, and repair steel and concrete piles using both visual and NDT methods. As a result, we identify defects early and extend asset lifespan.

Drainage and Culvert Works

We conduct CCTV surveys, blockage removal, and installation of protective grilles and flow control systems. In turn, this helps maintain efficient drainage performance.

Sluice Gate Repair and Replacement

We inspect, service, and replace sluice gates to ensure reliable water control. Furthermore, we minimise disruption during installation works.

Salvage, Rigging and Lifting Support

We deliver professional underwater rigging, slinging, and load handling to support construction and recovery operations. Therefore, lifts are completed safely and efficiently.
