Permanent & Temporary Cube Pontoons

Modular Cube Pontoons provide incredible robust, stable pontoons that can tolerate extreme weather yet offer unrivalled versatility

High Density Polyethylene (HDPE) cubes quickly connect together by inserting a connection pin and simply turning it through 45 degrees to lock it into place. With a cube weight of just 7kg the cubes can be easily moved around and built into virtually any shape and size.

The cubes have a hard wearing non-slip surface making them safe for use in all conditions, are fully UV stabilised and being HDPE don’t suffer from any corrosion issues or require any regular maintenance. HDPE is also recyclable making the whole system environmentally friendly.

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

The modular design allows them to flex in rough seas preventing damage to the pontoon whilst the shallow draft of just 25mm unladen allows the use in shallow water when required.

We hold large stocks of both standard cubes and Low Profile Cubes for clients that require a lower freeboard

When a higher load capacity is required the cubes can be double or triple stacked to increase the safe working load proportionally.

Along with the cubes we stock of a wide range of accessories allowing the easy installation of complete pontoon systems. Accessories include: Cleats, Fenders, Handrails, Winches, Access Ladders, Lights, Lifting Gantries and Mooring Attachments.

Our experienced engineers will design your pontoon in our 3D CAD system to ensure that it meets your requirements and our experienced installation teams will ensure that the completed pontoon exceeds your expectations.

We hold a large rental stock of Modular Cubes and associated accessories available for both long and short term hire throughout that UK.

More Info

Modular Cube Pontoon Systems have a wide range of uses including: Fish Farms, Working Platforms, Bridge Repairs, Pumping Platforms, Marina’s, Sailing Clubs, Drive On Docks, Access Ways and many more. With a stiff wire mesh attached, a cube pontoon can become a floating debris barrier, ensuring rubbish doesn’t continue its’ journey downstream, polluting our environment.

We also stock a wide range of access ramps, gangways and mooring systems to provide you with a complete solution to your pontoon requirements.
