Rock Stabilisation Underwater

Rock stabilisation underwater is a specialised field that requires precision, solid experience, and advanced equipment. Sjøentreprenøren has extensive experience in securing structures, quays, tunnels, and seabeds against landslides, slips, and erosion – factors that otherwise could threaten both safety and infrastructure along the coast. Our services are essential for creating stable and safe conditions where natural forces place extra demands.

Unstable rock and cliff formations underwater pose a significant risk to both people and assets. With the right rock stabilisation, we can prevent landslides and slips, protect important facilities and foundations, and reduce the risk of operational downtime and costly repairs. In this way, we help extend the lifespan of critical infrastructure.

We utilise a wide range of documented methods and specialised equipment to deliver safe and durable solutions, even under the most demanding conditions. Our divers and professionals carry out everything from bolting and scaling to injection to stabilise loose stones, rock formations, cracks, and cavities.

The work is carried out using specially built drilling rigs and advanced stabilisation systems, carefully adapted to the challenges we face underwater.
Throughout the entire process, we thoroughly document the work and follow strict quality and safety requirements. Thanks to modern technology and custom equipment, we can perform rock stabilisation even in the most inaccessible locations – always with an uncompromising focus on the safety of both our employees and the surroundings.

With Sjøentreprenøren as your partner, you get complete solutions from planning to completion. We combine many years of experience in demanding marine environments with updated equipment and specialised expertise. This gives you a safe and efficient execution, where quality, documentation, and safety are always at the centre.
