Marine and rivers

    Marines and rivers

Interserve is committed to protecting the health and heritage of UK waterways. It's a job we've been doing for more than 100 years which means we have a complete understanding of working in marine and river environments.

In-shore marine and river projects are of huge importance to everyday life in the places they affect and are often carried out in the full glare of the public eye. To maintain their reputation, we help clients engage with local communities, by keeping the public informed at every stage of the project and by minimising disruption and environmental impact.

Our floating plant has enabled us to relieve road congestion by using rivers and waterways as a transport network during construction, while minimising our carbon impact and delivering on our sustainability commitments. It also means we can carry out projects that are inaccessible from the land.

The experience of our highly skilled team provides assurance that we can deliver projects efficiently and effectively.

Our knowledge and capabilities cover all areas of the sector, including:

  • In-shore marine - port, harbour and marina development, coastal defences, construction and maintenance of bridges, pontoons, jetties, wharves and piers
  • Rivers - river walls, flood protection, dredging, dam construction
  • Heritage - maintenance and refurbishment of the infrastructure of Britain's waterways.


Operating nationally and internationally, we deliver a range of consultancy and professional services for clients.
