Our plastic cube pontoon systems are ultra-strong, making them suitable for both protected and unprotected environments. Frequent waves and high winds will not be a problem for these flexible and versatile cube pontoons.  Cube pontoon systems are also extremely lightweight, making installation and handling easy whilst still but providing a pontoon that is strong and durable.

These high-density polyethylene pontoon cubes are quickly and easily connected together by inserting a connection pin.  Then it's just a simple 45-degree turn to lock them into position. The pontoon cubes are moulded with a hard-wearing non-slip surface and although our cube systems are suitable in all depths of water, the pontoons have a very shallow, unladen draft allowing them to be used in water of just 25mm depth.

Cube Pontoons can be used to build pontoons of virtually any shape and size for both permanent and temporary installations in a wide range of locations.

  • 100% recyclable
  • Resistant to corrosion
  • Resistant to acids
  • Resistant to gasses
  • Resistant to hydrocarbons

These cubes are also capable of floating heavy, working load capacities as they can be double and triple stacked. A longer connecting pin passes through the pontoon cubes from top to bottom making this pontoon system very stable and capable of supporting extremely heavy loads.  They are ideal as work platforms on water and will hold quite heavy machinery.

Our cube pontoons can be integrated into any existing dock, transforming your access and docking capability without major redevelopment. This makes them versatile and cost-effective for the end-user.  These docks can be rearranged and transformed into a new layout within seconds. There's no need for heavy equipment to lift the pontoon from one location to another.

Cube pontoon systems are suited too many environments including waterparks, boat moorings, canoe launches, domestic lakes and ponds, events, temporary mooring, marinas and many other domestic and industrial locations. They can be used by contractors to float machinery, plant and a variety of other heavy items and make ideal work platforms on water.

Each of the cubes has four connecting points and only one pin is required to hold four cubes together. Anchoring of the pontoon system is simple and can be achieved using conventional methods, from bank side anchoring, free-floating on piles to allow for water depth changes or simply chained and anchored in place.
