Far North Fiberglass are international agents for one of the world's largest
floating dock manufacturers.
When you build your marina with these concrete floating docks, you’re
getting the innovative, patented designs created by Rixö-bryggan of Brastad, Sweden. This
system was created and designed to withstand the storms of the North Sea, so no matter what
extreme conditions your site experiences, these concrete floating docks are tough
enough to stand up to them.
Our concrete floating docks and wave attenuators are formed with a polystyrene
core and an outer concrete shell. Pressure-treated wooden whalers are added as a standard
feature on each pontoon. The top of the system is given a non-slip walking surface.
The connection system is the secret to the strength of these concrete
docks and breakwaters. Conventional concrete systems connect pontoons together by stringing
whaler boards connected by threaded rod between the sections. The problem with the conventional
connection system is that, as the pontoon moves in the waves, stress is being placed on the
concrete in the areas above and below the threaded rod. Over time, the stress may lead to
fractures or cracking of the concrete in the areas above and below the threaded rod.
Unlike conventional systems, this system is connected with cables that run inside
the length of the pontoon and are hydraulically post-tensioned. As the system moves, the
majority of the force is absorbed by the cable and does not negatively effect the concrete.
While the cables absorb the energy of the movement between the sections, the system will
maintain a high amount of rigidity and will provide a very stable walking surface.
We’re ready to design and install concrete floating docks and wave attenuators
in virtually any dimensions for your needs. Three of our most popular models are:
- Model 400 Floating Dock
- Model 450 Heavy Duty Dock or Light Duty Wave Attenuator
- Model 850 Heavy Duty Wave Attenuator
The Rixö-Bryggan Model 400 is designed as a commercial marina dock system. The
standard walkway section is 50' long and 8' wide. Standard finger piers are 4' wide and vary in
length based on the desired slip length. Both walkways and finger piers have a freeboard of 22".
The finger piers can feature corner walkways at their connection point to the main walkway. This
system has a carrying capacity of 50 pounds per square foot.
The Rixö-bryggan Model 450 may be used as a heavy duty dock or a light duty breakwater.
It stands a total of four feet in height, and like the Model 850, it will provide two feet of
free board. But, unlike Model 850, it is not constructed with flanges and only two feet of
concrete is submerged below the water. The wave dampening effect is, thus, significantly less
than that provided by Model 850. The concrete system is so strong and stable that a full size
automobile may be safely driven on it.
The Rixö-bryggan Model 850 is designed as a heavy-duty breakwater standing six feet
six inches in height. Because the energy of a wave travels in an elliptical motion, the depth of
a floating breakwater is very important. If the bottom of the ellipse is greater than the depth
of the breakwater, a portion of the wave's energy will travel under the breakwater. Accordingly,
the deeper the breakwater, the greater the wave dampening effect of the structure. The "legs"
on the Model 850 also trap water inside the frame of the breakwater and effectively adds to the
wave dissipating mass of the structure.
