We are the Experts in our field
At Kaymac Marine & Civil Engineering Ltd., we specialise in delivering innovative and robust engineering solutions across marine, civil, and underwater environments. With nearly 50 years of experience and a team of in-house specialists—including chartered civil engineers, commercial divers, and site operatives—we provide safe, sustainable, and cost-effective solutions that stand the test of time.
From challenging subsea projects to complex infrastructure renewals, our expertise lies in navigating high-risk environments both above and below the waterline.
End-to-End Project Delivery
We operate a fully integrated project model—Detect, Diagnose, Develop, Deliver—ensuring seamless execution from initial investigation through to design, construction, and handover. Whether acting as principal contractor or supporting tier-one organisations, we are trusted to deliver works on some of the UK’s most critical infrastructure.
Core Areas of Expertise
Marine & Subsea Civil Engineering
We began as a specialist diving contractor in 1976, and marine civil engineering remains at the heart of our business. Our skilled teams work in some of the most demanding tidal, confined space, and underwater environments to inspect, maintain, and repair vital assets.
Coastal & Inland Waterway Engineering
We are experts in delivering solutions that protect against erosion, flooding, and structural deterioration. Our works include underwater structure repairs, scour protection, culvert maintenance, cofferdam installation, pile encapsulation, and temporary access systems such as pontoons and working platforms.
Civil Engineering
Our civil engineering services span bridges, embankments, tunnels, culverts, retaining walls, and flood defences. We work across rail, road, and water infrastructure, with a proven track record in emergency response, temporary works, and long-term structural upgrades.
Specialist Diving Operations
Our qualified commercial divers conduct underwater inspections, surveys, concrete pouring, structural strengthening, welding, demolition, and protection works. All activities are carried out with strict adherence to HSE and industry safety standards.
Ports & Harbours
We support the long-term maintenance and development of port and harbour infrastructure, including lock gate repair and replacement, fender systems, and marine asset life extension works. We work regularly with port authorities to ensure safe and efficient operations.
Water Utilities
We work with water companies and framework contractors to maintain essential infrastructure. Our services include long sea outfall installations, spillway rehabilitation, dam maintenance, fish deterrent systems, and intake structure repairs.
Rail Infrastructure
Our in-water civil teams are fully trained to PTS standards, delivering critical works to safeguard rail infrastructure—including bridge supports, culvert and scour repairs, slope stabilisation, and emergency asset protection.
Energy & Nuclear
We support the energy and nuclear sectors with specialist marine works in secure, high-risk environments. Our projects include decommissioning, marine structure maintenance, and innovative solutions for power stations and coastal energy facilities.
