4 Reasons Concrete Floating Docks are the Best Choice for your Home or Marina
If you think about the environmental stresses present in a marina environment, you realize the benefits of a stable structure that floats on top of the water. Marina owners throughout the country recognize the elements which make concrete floating docks the most practical, cost-effective choice.
What’s under the water?
Concrete floating docks are perfect alternatives to wooden docks. They’re more environmentally safe, are safer for pedestrians, and have a longer lifespan. (Click on the image above for a larger version).
When you first begin to plan your new dock, it’s important to consider what’s under the water. What type of floor does this body of water have? If it’s very soft and muddy at the bottom, the pilings for a fixed dock would be difficult to secure. Likewise, if you have a hard rock shelf at the bottom, it would also be a challenge to set the pilings in place. Next, you need to know how deep the water is; if the depth at high tide is greater than 20 feet, fixing pilings becomes very complicated. It’s obvious why the largest cost of a wooden dock results from planting the pilings.
Floating docks, however, can be secured in various ways depending on the layout and the direction of the weather. The anchoring system for your dock will be custom-designed to prevent any horizontal movement in response to the forces of wind and wave, while allowing natural vertical movement with the tide.
Flotation: why not wood?
Have you wondered why floating docks aren’t simply made with wood? It turns out that, over time, wood is actually not very buoyant. Its cells eventually become entirely saturated with water and it sinks. Furthermore, wood is susceptible to the action of many different marine creatures that bore into it (as any owner of a wooden boat will attest.) Treating wood against these biological attackers causes it to lose buoyancy.
Expanded polystyrene (EPS) is commonly used for durable, heavy-duty flotation in houseboats and docks. It’s composed of 97% air, and one cubic foot of EPS can support sixty pounds of weight. This mostly-air material is sealed inside the core of each section of Nordidock’s floating concrete dock, making it permanently buoyant. The terrific buoyancy of the EPS supports the weight of the concrete, and the combination of the two materials results in a floating dock which is so heavy that it won’t respond readily to wave chop or moving loads.
Life cycle cost
When budgeting for a new dock, you’re committing yourself to all the upkeep it will need throughout its lifetime. Concrete and foam, both of which are inert environmentally friendly materials, require virtually no maintenance. Utility conduits are safely sealed within the core of the dock sections, protected from all corrosive elements.
Concrete docks valued nationwide
While NordiDock serves the residents of New Jersey, New York and Connecticut, and Massachusetts, concrete floating docks are increasingly valued in other regions of the country as well. According to the Concrete Joint Sustainability Initiative, “When a wooden floating dock in the Port of San Diego had deteriorated to the point of having to be torn down, the owners chose to replace it with a floating dock assembled from precast concrete modules. The durability offered by the precast dock was a key consideration, and the modular design allowed a few standard-sized sections to be used in the creation of a variety of configurations.”
A discussion of a local dock in the Martha’s Vineyard Times includes this comment: “The reason concrete floating docks were recommended are; concrete floating docks are safer for the boaters as they rise and fall with the tide and keep the stern of the boat at dock level, they require less maintenance than wood, are far more fire resistant, and are less expensive to install.”
The Naval Air Station in Jacksonville, Florida has a new system of concrete floating docks. Their Public Works Construction Manager announced: “Recreational boaters at NAS Jacksonville will soon enjoy safe haven thanks to a new concrete floating dock system with quality boating amenities.”
5 Reasons to Choose a Concrete Floating Dock for your Home or Marina
Pedestrian Safety
The footing on NordiDock concrete floating docks always feels solidly safe. Nonskid surfaces allow for confident movement when boaters are juggling awkward objects into and out of their craft. Heavy floating sections mean that the dock stays level and solid-feeling, rising and falling with the tides.
The connecting units on NordiDock concrete floating docks are built to ensure that no voids develop at the joint between two dock pieces. This is crucial for the safe use of dock carts and other marina equipment.
Finally, the 34,000 lb weight of a 50-foot section of NordiDock concrete dock means that it will stay solid as a rock when struck by high waters and storm winds. Photographic evidence in the wake of Hurricane Sandy shows that concrete floating docks withstood the forces of the storm better than docks constructed from any other materials. From now on, it looks likely that new dock construction in the states of New Jersey, New York, Connecticut and Massachusetts will need to take serious future storms into consideration.
Boat Safety
Since NordiDock dock sections float with 24 inches of freeboard, the lines will always stay fixed at their original tension. Floating docks put an end to the calculation of how much extra line is needed to compensate for rising and falling tides, and boats moored close to each other won’t suffer damage from slack lines. Boat owners can also feel confident placing their bumpers, knowing that there won’t be any problems when the tide changes.
Longer life-span than wood
When you pay for the construction of a new dock, you expect it to be a long-lasting, durable structure. The fact is, though, that wooden docks require almost constant upkeep. Concrete is an inert material that barely deteriorates over time, and a floating concrete dock will actually require 90% less maintenance than wood. The concrete structure is non-flammable and will not rot or corrode.
Serious environmental advantages over wood docks
There are no wooden components requiring chemical preservative treatment, so a floating concrete dock does not release toxins into the water. As a matter of fact, concrete is so benign to the health of marine organisms that the port authorities in Georgia actually installed specially configured concrete panels at their public docks in order to foster a healthy community of marine organisms.
Easy customization
Because floating concrete docks are modular, they can be configured to whatever specifications your site demands. Attachment to anchors or pilings can easily be designed, taking into account the unique exposure of your marina to wind and wave action. Furthermore, utility conduits are incorporated into the construction at the beginning, so that electrical lines and cables remain securely and permanently housed in the concrete.
