Work Docks & Bridges

Floating Work Docks
Payloads up to 1000 kg/m² – Portable
 
Our floating work docks are built tough for Australian conditions and suited to a wide range of applications—whether you need a stable platform for construction, machinery access, floating equipment, or temporary on-water accommodation. These docks can be fully customised to any layout or size, giving you the flexibility to build exactly what you need, where you need it.
 
With over seven cube types available, payloads range from 220 kg/m² up to 700 kg/m², and can be triple stacked to reach a maximum capacity of 1000 kg/m². Custom colours are available to suit your brand or project needs, and logos can be added directly to the cubes for a professional finish.
 
These platforms are incredibly versatile, operating in as little as 25mm of water. They can also be converted into motorised barges, floating sheds, offices, homes, or even vehicle support platforms. Modular in nature, they can be anchored, fixed to pylons, or attached to existing structures with ease.
 
Made from high-grade HMWHDPE and enhanced with anti-static, UV, and impact-resistant additives, these docks are built for strength, safety, and longevity—lasting over 15 years under regular use. They're recyclable, eco-friendly, and completely free from metal, making them safe for marine life and harsh environments.

Bright, high-visibility colours and anti-slip surfaces enhance safety, while the smooth, rounded design ensures no sharp edges. These docks are built for heavy-duty use, but still lightweight and easy to transport, assemble, and reposition.
 
Whether it’s temporary or long-term, small-scale or industrial, our floating work docks provide a stable, reliable, and environmentally responsible solution.
