Guide to Building a Floating Dock – Construction Tips, Materials & Savings
Table of Contents
Stepping onto a dock that appears to rest lightly on water is almost magical. A dock that is fixed can’t give you the same sense of connection to the lake or water. It moves a little, but not too much. A floating dock is a popular choice for homeowners, property managers, and hobbyists. A floating dock is not only practical but can also change how you use your waterfront.
Supreme Floating Docks have seen clients approach this problem from different angles. Some customers want a fishing platform. Some people envision a place where they can launch kayaks or tie their boats up. Some people want to relax, with their feet dangling over the edge of the cliff and a coffee in hand, while watching the sunrise. You need to be aware of a few factors before you grab some tools and lumber: the materials, cost, design options and common mistakes.
Why Build a Dock Instead of a Fixed Dock
These fixed piers will be permanently embedded in the soil. These piers will last a long time and are very sturdy. These piers can be costly. They rise and fall with the water. They are particularly useful in rivers and lakes with fluctuating water levels.
People often ask “Why bother to build a floating dock?” The answer is flexibility. It will not be left stranded during droughts or drowned under floodwater. It adapts its environment.
How to Build a Floating Dock: the Basics
If you’ve ever looked up how to build floating docks, then you’ve likely seen many different pieces of advice. Some advice is good, while others are not. It depends on the purpose of your dock. Are you looking for a platform on which to relax? Are you looking for a dock strong enough to hold a motorboat?
Most people follow this general procedure:
- Plan and Design: Determine the size, shape, and purpose. It’s a square or round platform? It will be square. Consider an L-shaped platform to gain more space.
- Frame Construction – For durability, frame construction is usually constructed from aluminum or pressure-treated timber.
- Floats and barrels provide dock buoyancy. Some DIYers use dock floats while others use barrels.
- Decking Materials: Depending on your budget, you can choose from wood planks or composite decking boards.
- Docks that are not properly anchored can drift. Anchors like cables or poles, as well as chain anchors, will keep your dock in place.
Here is the bird’s-eye view. Anyone who has been there knows that the devil is in the details.
DIY Floating Dock Plan – Pros and cons
The idea of building your own DIY dock is appealing to many people. They then go to a hardware store and start building. This method can be used for smaller backyard docks. This is a cost-effective and rewarding method.
Homemade docks are not without their challenges. If you do not calculate the buoyancy properly, you could end up with an unstable platform that sinks or topples over when more than two people are standing on it. If you fail to anchor your dock properly, it will drift.
Many people turn to modular solutions offered by companies like Supreme Floating Docks. You can still do it yourself, but don’t worry about engineering.
What are the best materials for floating docks?
People often ask what the best materials are for floating docks.
- Wood Dock Frames – Pressure-treated lumber is classic and affordable but requires maintenance.
- Aluminum Dock Frames – Lightweight, strong and resistant to rot. However, they are expensive initially.
- Decking Material: Wood is warm but needs to be sealed. Composite decking is stronger, more resistant to the weather and needs less maintenance.
- Floats are a great alternative to barrels for a floating dock. Dock floats or foam blocks that have been designed with balance in mind will be much more reliable.
When building a floating dock, consider more than just the cost. The materials that are less expensive today may be cheaper tomorrow, but will require more maintenance.
Cost to Build a Floating dock
The tricky part is this. Everyone wants to know the price of a dock on floats.
Spend between $500 and $1500 for DIY projects with reclaimed barrels and basic lumber. The cost increases if you want to build a product that is durable, safe, and professional. Docks and modules that are prefabricated can range in price from $2,000 to $10,000 depending on their size and materials.
Factors affecting cost include:
- Size (small boat platform vs. large fish dock)
- Materials (wood, aluminium, engineered barrels and floats)
- Location (remote Lakefront or easy Driveway Access).
- Instead of doing the work yourself, hire professionals to do it for you
If you remodel your kitchen within a limited budget, the quality, durability, and satisfaction will not be the same.
Floating Dock Design Ideas
It’s the most exciting part to come up with new floating dock designs. You’re not limited to a rectangle platform.
- Straight walkway – Simple and functional. Ideal for boat tie ups.
- This design is ideal for those who want to relax or fish.
- Modular platforms: Create flexible and expandable layouts.
- Docks of the pontoon type – stable enough for large gatherings.
- Railings, rod holders, and seats can all be added to fishing docks.
A floating dock offers much more than a simple platform. It is an extension of your personality.
How to Build a Floating Dock: A Step-by-Step Guide
Here is a guide to a floating dock for those who like structure.
- Choose your design (platform, L-shape, walkway).
- Pick materials: frame, decking, floats.
- Build the frame.
- Attach barrels and floats underneath.
- Decking the top is a good idea.
- Anchor securely using poles, cables or chains
- Before inviting guests to your home, test the stability of the house.
The concept of each step is easy, but there are challenges.
Floating Dock Installation Tips
Installation of a floating dock: Some tips from others’ experience
- Before floating, build on a flat surface.
- Overestimating buoyancy is preferable to underestimating it.
- Anchor Smart: Shallow water requires poles, while deeper waters may require chains.
- Avoid installing during storm season.
- Plan your maintenance. Even the best docks need to be inspected on a seasonal basis.
Although it may seem obvious to skip a step, this can lead to costly mistakes.
Floating Dock Maintenance
Work does not end when your dock is in the water. Maintaining your dock will ensure that it lasts. Cleaning algae, inspecting the anchors, resealing wooden decking, and replacing hardware that has rusted is all part of maintaining your dock. What’s the good news? Composite decking and frames made of aluminum are easier to maintain than older designs.
How to build a floating dock with barrels
It would be a grave mistake not to mention the classic way of building a dock floating using barrels. Since decades, people strap 55-gallon drums to wooden frames for buoyancy. It isn’t perfect, but it does work. Barrels can leak, shift or even collapse in the sun. Modern dock floats and floating devices such as foam blocks are more durable and safer for long-term use.
For those who wish to build their own dock, barrels are still an excellent choice.
