Premium Cube Docks
Premium Cube Docks
Single & Double – Highest Payload Per m2
Our Single and Double Premium Cubes are a game-changer when it comes to strength, buoyancy, and visual appeal. Thanks to their interlocking curved edges and smart wedge-shaped design, they offer greater stability than standard cubes and can handle over 360kg/m² with ease.
These are the strongest cubes in our range — ideal for drive-on/off docks, floating walkways, berths, pontoons, jetties, and any high-traffic area where performance matters.
Each unit features extra curved sides that not only enhance structure but also give your dock a sleek, modern edge. Whether you’re setting up a commercial operation or a personal watercraft launch, these cubes keep your platform solid underfoot and looking sharp.
Available in Blue, Grey, and Orange as standard, or customise with your own colour minimum 60m2 (240pce). Like all modular systems, they can be extended, reshaped, moved or packed down as needed.
Made from high-density, 100% recyclable HDPE, these cubes are engineered for Aussie coastal conditions — UV-resistant, non-slip, and built to handle saltwater, chemicals, oil and temperature extremes without cracking or fading.
