This is a very reasonable alternative which combines the flexibility and cost-effectiveness of pressure-treated wood and the stability and mass of a concrete float.
A wooden pontoon/concrete float from SF MARINA is a very cost-effective alternative. It combines the flexibility of a wooden pontoon with the weight of a concrete pontoon. This pontoon consist of a sturdy superstructure of pressure-treated wood over floats of steel-fibre reinforced construction. The concrete and styrofoam construction of the float makes the pontoon virtually unsinkable. The decking is planed wood. It can be built to required length without visible joints. Pontoon type 31 is very suitable for harsh climate and can withstand being frozen-in during Winter. Normally, the pontoon would be moored
