Bridge foundations

When it comes to building solid and durable bridge foundations in the sea, specialised expertise, the right equipment, and in-depth knowledge of complex underwater ground conditions are required. The marine contractor has extensive experience with foundation work for bridges and other large structures in demanding marine environments. We offer complete and customised solutions for bridge foundation work, including advanced methods such as the use of caissons, drilling, blasting, reinforcement, and casting – even at great depths.

Experts in caissons and marine foundation solutions

Caissons are a highly effective method for establishing stable bridge foundations in sea and river environments, even on challenging ground and at great water depths. Our professionals have long experience in the design, manufacture, and installation of caissons, and can take on the entire process from planning to completed foundation. This ensures safety and quality at every stage, and guarantees that the bridge foundations stand firm for generations – regardless of external stresses from currents, waves, and ice.

Complete delivery of bridge foundations in the sea

We take responsibility for the entire foundation work in the sea, from the initial ground investigations and planning, to the fully installed bridge foundation. This includes:

  • Accurate design and selection of the right method for each project
  • Drilling and blasting of the seabed for optimal anchoring
  • Manufacture and installation of caissons tailored to ground conditions and load
  • Reinforcement and casting with high demands for precision and quality
  • Continuous control and quality assurance throughout the process

Our experience with demanding projects ensures efficient execution, high safety – and minimal impact on the marine environment.
