GCMarine’s pontoons are a heavy-duty , built tough and completely customisable. We offer a range of pontoons for commercial projects including piled pontoons, strut pontoons, and cable pontoons. Contact us today for a quote!

Piled Pontoons

GCMarine’s piled pontoons are a heavy-duty pontoon. The deck is constructed using 50MPA concrete with internal steel reinforcements rods for maximum strength. For floatation, a foam void is used with a maximum of 7% absorption rate and lined with a high strength HDPE liner to eliminate any marine life entering the void. The pontoon is then topped off with first grade marine carpet. Conduits are also provided to the full perimeter of GCMarine pontoons for power and water connection.

Piled Pontoons Types:

Spun concrete piles: These piles are well suited to pontoons on main rivers and properties that are in a high wash zone. Spun piles are pre-formed by an Australian manufacturer giving them rated engineering certification. With a range of breaking strengths available we will tailor the best type for you.

Steel Piles with Black Sleeves: Steel piles are again in the heavy duty range and offer the flexibility for a tall pile, meaning spun piles are generally limited to around 16m where as steel piles are available in 16m lengths and can be cut and welded onsite to whatever size is required (within engineering limits). For example following the Brisbane River Floods in 2011, most piles are now between 16m and 22m and use steel piles due to the lengths required to meet the new Q100 flood level.

Insitu Piles: These are the alternative option for pontoons in quiet areas, which does not encroach onto beach space. Insitu piles comprise of a steel cage, filled with concrete and a PVC casing.

Cable Pontoons

GCMarine’s cable pontoon system is a cost-effective solution for commercial projects in quieter canals, lakes and rivers. The cable system uses marine-grade stainless steel cables, which are connected to the rear two corners of the pontoon and runs back to concrete mooring blocks on the land making a X shape. With cable pontoons, the gangway has to be positioned in the centre of the pontoon as this doubles as a brace for supporting the pontoon.

Our cable pontoons are made using 50MPA concrete along with galvanised rebar internally in the pontoon for maximum strength, as well as a foam void with a maximum of 7% absorption rate for the flotation component. To top all this off we finish our pontoons in a high strength HDPE liner to keep the marine life from entering the void.

Strut Pontoons

GC Marine’s strut pontoon range is a great choice for commercial projects in quieter canals and waterways. The strut pontoon range are in the mid-section of the price range but still offer great strength and longevity.

The strut pontoon range is made up of a heavy duty concrete deck pontoon and then installed with the gangway on one end of the pontoon and the aluminium strut arm on the opposite end. This supports the pontoon from in/out movement. A set of cables in a X pattern are also connected from the rear two corners of the pontoon back to concrete mooring blocks on the land end, which stops left/right movements.
