A floating dock is a practical and flexible solution to accessing water. You can use the floating dock to relax, go swimming or boating. Not all floating docks, however, are the same. Materials used to build them play an important role in how durable they are, how much maintenance is required, and how they stand up to the weather. Understanding the pros and cons for each material is essential before installing a floating dock.
Materials Commonly used for Floating Docks
The majority of floating docks are made up of a combination frame structure and flotation unit. Frame materials come in many varieties, with their own advantages and disadvantages. Let’s look at the most common materials.
1. Wood
Since many years, wood has been used as a dock material of choice. Wood is a natural, warm material that looks beautiful in outdoor environments. Commonly used pressure-treated cedar and pine because they are resistant to moisture and insect.
Pros:
- Natural and attractive appearance
- Easily available
- Cost-effectiveness is possible
Cons:
- Maintenance (staining, painting) is required
- Over time, they are prone to splitting and warping.
- Synthetic materials are less resistant to water over time.
2. Aluminum
Aluminum is light and corrosion resistant, which makes it perfect for floating docks. It is strong and durable, and can be used both in saltwater and freshwater environments.
Pros:
- Lightweight yet durable
- Corrosion-resistant
- Low Maintenance
Cons:
- Initial costs tend to be higher
- May heat up in direct sunlight
- The wood does not look as “warm”
3. Composite Materials
Composite decking is becoming more popular. Composite decking is made of recycled plastics and fibers. Composite decking looks like wood, but requires less maintenance.
Pros:
- No sanding is required.
- The wood will not split, rot, or splinter
- Select environmentally friendly products
Cons:
- Initial costs are higher
- Surfaces are slippery when they’re wet. Choose textures that have slip-resistant properties.
- It may not feel the same as real wood
4. Plastic (Polyethylene and PVC)
Modern floating docks use rotomolded plastic floats as their buoyant base. The majority of docks are made entirely from plastic. The docks are simple to install and can also be rearranged.
Pros:
- Highly resistant to UV and corrosion
- Easy to install and lightweight
- Outstanding buoyancy
Cons:
- It is difficult to compare the aesthetic appeal of composite or wood.
- Docks made from aluminum may not be as sturdy as those made from steel.
When selecting materials, there are several things to consider
The right material for your floating deck is determined by several factors.
- Location: In saltwater environments, materials that resist corrosion such as aluminum or marine grade plastics are required.
- Materials like composite, wood and plastic are cheaper. Aluminum and composite materials cost more to buy.
- Maintenance Preferences If you are looking for a dock that requires minimal maintenance, plastic or composite materials will be the best choice.
- Think about the aesthetics of the dock and how it will look in relation to your home or the shoreline. Composites are sleeker and more modern than wood.
Final Thoughts
The material you choose will have a direct impact on the appearance, performance and durability of your floating dock. Each material has advantages and disadvantages. The key is to find the balance that suits your lifestyle and needs. There are many floating dock materials that will suit your waterfront. You can choose from those with minimal maintenance requirements, strength and durability, or even a natural look.
