Building Pontoon Systems Since 1992

Intermarine is a UK-based specialist in the design, manufacture and installation of pontoon systems, delivering high-performance marina infrastructure and berthing solutions for both leisure and commercial applications.

We design and build aluminium, steel and concrete pontoons for a wide range of uses, including marinas, harbours, ports and commercial docking facilities. Every system is engineered to suit site-specific environmental conditions, ensuring durability, safety and long-term performance.

Alongside new installations, we provide expertise in:

  • Heavy-duty commercial pontoon systems
  • Floating structures and access platforms
  • Pontoon maintenance and asset management
  • Marine engineering inspections and condition surveys

We also support projects at the earliest stages, providing feasibility studies, budget costing and optioneering, alongside guidance on statutory approvals including MMO, Environment Agency and Port Authority licence applications.

Our approach combines proven design with high-quality materials to deliver robust, low-maintenance pontoon systems that perform in demanding marine environments.
