We’re a multi-award-winning specialist marine civil engineering contractor with a well-earned reputation in our field.

Since 1976, we’ve worked to build our excellent reputation. Kaymac started as a small team of dive operatives specialising in underwater problem-solving. Today, we are still a privately owned, family-run business with dedicated multi-skilled teams in three locations, delivering challenging civil and marine engineering solutions; above and below the water line. We have UK-wide clients in transport, nuclear, water utility and marine ports and harbour sectors.

We have been an innovator in the specialist repair and maintenance industry for decades. Our focus on marine civil infrastructure repair has allowed us to develop a complete end to end professional service for our customers (Detect, Diagnose, Develop, Deliver). We unravel the complexities of structure repairs, protection and maintenance challenges in marine environments through early engagement development, offering our long serving people challenging work with the opportunity for personal development, and ensuring that the life of our customers infrastructure assets are safely and sustainably extended.
