Build a Floating Dock on a Budget Using PVC Pipe

A relaxing, affordable floating dock is within your reach with PVC pipe. Constructing your own dock using basic PVC materials is an easy weekend project that can completely transform your backyard.

This straightforward guide will walk through all the steps needed to DIY an incredible floating oasis on a budget.

Gather the Necessary Supplies

PVC pipe, endcaps, deck boards, primer, cement, and screws form the foundation of your floating dock. Determine the overall size you want your dock to be and purchase the correct amount of 10-foot PVC pipe lengths.

Here's a full list of everything you'll need:

• 10' segments of schedule 40 or 80 PVC pipe
• Matching PVC endcaps
• Exterior pressure-treated lumber for decking
• PVC primer and cement
• Stainless steel screws

Choose the Right PVC Pipe

Schedule 40 PVC pipe with a diameter of 1.5 to 2 inches works well for most floating dock projects. Schedule 80 PVC has a thicker wall and greater rigidity, but is more expensive.

Make sure to purchase UV-resistant pipe designed for outdoor use.

Don't Forget Endcaps

Watertight PVC endcaps are essential for sealing the ends of the pipe frame. This prevents water from entering the pipes and destabilizing the dock.

The number of endcaps needed equals the number of PVC pipe segments.

Pick Durable Deck Boards

Pressure-treated exterior lumber is ideal for the dock's surface. Look for deck boards rated for ground contact and wet conditions.

Cedar, redwood, or composite boards also resist water damage well.

Assemble the Pipe Frame

With all your materials ready, it's time to start construction. Assembling the pipe frame is the first crucial step.

Cut Pipes to Size

Measure and mark your PVC pipes to the appropriate length if needed. Use a hacksaw to cut through the pipe with straight, smooth cuts.

Wear eye protection when cutting.

Connect the Pipes

Apply a coat of PVC primer to both ends of the pipes to prepare them for cementing. Then apply PVC cement to bond the pipe fittings together.

The cement chemically fuses the pieces into waterproof connections. Follow the manufacturer's instructions.

Attach the Endcaps

Glue a watertight PVC endcap onto each end of the assembled pipes with PVC cement. This seals the frame and allows it to float.

Give the cement time to fully cure before placing the dock in the water.

Add Deck Boards for Surface

With the underlying frame complete, now you can attach deck boards on top.

Cutting Deck Boards

Measure the overall length and width of your pipe frame. Cut your deck boards so they fit flush across the frame with minimal overhang.

Fasten the Boards

Pre-drill holes in the deck boards to prevent splitting. Use exterior stainless steel screws to fasten the boards to the PVC frame below.

Space screws every 12-16 inches for stability.

Finishing Touches

Once secured, sand any rough edges on the deck boards. You can also coat exposed screw heads with sealant to prevent corrosion.

Flotation and Placement

One of the final steps is gently sliding your completed floating dock into the water. The buoyancy of the sealed PVC pipe frame allows the dock to float once assembled.

Consider adding anchors, cables, or weights if needed to stabilize the dock and prevent drifting.

Maintenance and Precautions

Like any outdoor structure, your floating dock will require regular upkeep and maintenance. Inspect the dock often for any signs of damage or worn parts.

Consider adding reflectors, railings, and caution signs to maximize safety. And never forget to have life jackets available when spending time on the dock.

After the easy DIY process, you'll be ready to kick back with an icy drink and soak in the rewards. A PVC pipe floating dock allows you to extend living space from the shoreline and enjoy relaxing over the water.
