Why Choose a Floating Dock?
A floating aluminum dock is a long-term investment in your waterfront property.
Rises and falls with the tide
Floating docks follow the water level, making them ideal for B.C.'s tidal coastlines and lakes with fluctuating water levels.
No pilings driven into the seabed
Unlike fixed docks, they avoid pilings driven into the lakebed or seabed, reducing environmental impact and permitting complexity.
Modular and expandable
Sections can be added, removed, or reconfigured as your needs change.
Virtually zero maintenance
Aluminum won't rot, rust, or warp like traditional wood docks — no constant refinishing.

Common Questions About Floating Docks
How long does it take to build a custom dock?
Most docks are ready in 4–6 weeks once materials arrive. Every dock is fabricated in our Sechelt shop, then delivered and installed anywhere in British Columbia.
How long will an aluminum floating dock last?
Our docks are built from marine-grade 6061 aluminum with fibreglass-reinforced mesh decking and puncture-proof floats, and are designed for a lifespan of 50+ years in B.C. tides, storms and salt water.
What sizes can you build?
Every dock is built to fit its site. Common sizes are 10 × 20 ft, 10 × 30 ft and 8 × 60 ft, and our largest builds include 8 × 140 ft, 10 × 120 ft and 24 × 60 ft docks.
How much weight can the dock hold?
Our docks are rated for a live load of 30 lb per square foot, with about 20 inches of adjustable freeboard above the water.
What keeps the dock afloat?
Plastic-encased foam floats by Barr Plastics — typically 6–7 under a 10 × 20 ft section. They are puncture-proof, so the dock stays buoyant for decades even in rough conditions.
Will a floating dock work in rough or exposed water?
Yes. For sites with heavy wave action we can add wave defender and wave attenuator floats to calm the water around your dock.
Can I add to my dock later?
Yes. Our aluminum floating docks are modular — sections can be added, removed, or reconfigured as your needs change.
Can you customize the dock?
Yes. Choose your size, layout, decking material and accessories — cedar accents, cleats, bumpers, lights, sound systems, built-in swim ladders, kayak racks and rollers, and benches.
Do you deliver and install the dock?
Yes. We deliver by water with our own marine equipment and install across B.C., including remote sites with no road access.
