heavy concrete pontoons

Concrete pontoons used for mooring small boats are the "backbone" of the marina. They are safe, firm, durable, and can withstand high loads. During operation the pontoons do not require special maintenance.

Advantages of heavy concrete pontoons:

  • constant height elevation, independent of fluctuations of water level
  • combination of massiveness and buoyancy
  • we can create a marina of any configuration depending of the waters and wishes
  • economic feasibility plus reliability and comfort
  • you can change the configuration of the marina and the number of places for mooring
  • Environmental perfection
  • lifetime of 25 years

Concrete pontoons are made of high quality hydraulic concrete with a special filler and metal reinforcement.

All external steel products subjected to hot galvanizing.

Concrete pontoons attached to the bottom of the waters with chains on the dead anchor.

Pontoons are joined with high-flexible fastenings and have cable channels for laying electric cables and pipelines.

The length of the concrete base 6 - 15 m
The width of the concrete base 2,4 - 3,0 m
The height of the concrete base 0,95 - 1,20 m
The height of elevation 0,45 - 0,60 m
specific weight 1,1 - 1,9 tn/cu. m
permissible load 250 - 500 kg / sq. m
Composition: hydraulic concrete, filler - styrofoam, steel reinforcement

Optional accessories: mooring fingers, bollards, wooden deck, ladders, power lines, pipelines, service column with water dispensing taps and electrical connectors.

Mooring is possible as directly to the pontoons and so to the mooring fingers of any sizes mounted perpendicularly, what allows organize moorage properly.
