A floating dock provides a flexible and practical solution for accessing the water. The floating dock can be used to relax, swim or go boating. However, not all floating docks are created equal. The materials used to construct them have a major impact on how durable, how much maintenance they require, and how well they can withstand the weather. Before installing a dock, it is important to understand the pros and cons of each material.
Materials commonly used for Floating docks
Most floating docks consist of a combination of frame structure and flotation units. There are many different types of frame materials, each with its own pros and cons. Here are the most popular materials.
1. Wood
Wood has been the material of choice for docks for many years. Wood is a warm, natural material that looks great in outdoor environments. Pressure-treated cedar or pine is commonly used because it’s resistant to moisture and insects.
Pros:
- Natural and attractive appearance
- Easy to find
- Cost-effectiveness can be achieved
Cons:
- Maintenance (staining and painting) is required
- They are susceptible to warping and splitting over time.
- Over time, synthetic materials become less resistant to moisture.
2. Aluminium
Aluminum is lightweight and resistant to corrosion, making it ideal for floating docks. It is durable and strong, and can be used in both saltwater and freshwater environments.
Pros:
- Lightweight yet durable
- Corrosion-resistant
- Low Maintenance
Cons:
- The initial costs are higher
- May heat up in direct sunlight
- The wood doesn’t look as “warm”.
3. Composite Materials
Composite decking has become more popular. Composite decking is made from recycled plastics and fibres. Composite decking looks like wood, but requires less maintenance.
Pros:
- No sanding required.
- The wood won’t split, rot or splinter
- Choose environmentally friendly products
Cons:
- Initial costs are higher
- Wet surfaces are more slippery. Select textures with slip-resistant properties.
- The wood may not feel as good as real wood
4. Plastic (Polyethylene & PVC)
As a buoyant base, modern floating docks use rotomolded floats made of plastic. Most docks are entirely made of plastic. Docks can be easily installed and rearranged.
Pros:
- Highly resistant to UV and corrosion
- Lightweight and easy to install
- Outstanding buoyancy
Cons:
- Comparing composite wood and composite plastic is difficult.
- Docks made of aluminum are not as durable as those made of steel.
There are many things to consider when selecting materials
The choice of material for your floating deck depends on several factors.
- Location: Materials that resist corrosion, such as aluminum and marine grade plastics, are needed in saltwater environments.
- Materials such as composite, wood, and plastic are less expensive. Aluminum and composite materials are more expensive to purchase.
- Maintenance Preferences Plastic or composite materials are the best option if you want a dock with minimal maintenance.
- Consider the aesthetics and the way the dock will appear in relation to the home or shoreline. Composites look sleeker and are more modern than wooden docks.
Final Thoughts
Your floating dock’s appearance, performance, and durability will be directly affected by the material you select. Each material has its advantages and disadvantages. It is important to find a balance that fits your lifestyle and needs. Many floating dock materials will fit your waterfront. Choose from materials that require minimal maintenance, are strong and durable, or have a natural appearance.
