Single Flooding Cube

Flooding Cubes For Drive On Docks
Curves Dock Entry – Same Size as Standard Cube
 
Flooding Cubes are designed to create a smoother, more natural drive-on and drive-off experience. Shown in the shaded sections of dock layout diagrams, these cubes are installed in the first two rows at the dock entry point — helping the dock gently curve into the water.
 
Flooding Cubes are the same size and cost as a standard single cube, making them a smart and optional upgrade for a more seamless approach.
 
Each cube includes two integrated valves — one on top for filling and one on the side for draining. A special tool is supplied to make it easy to fill or empty the cubes as needed. When filled with water, the cubes dip slightly below the surface to provide a more gradual angle into the dock.
 
Crafted from high-density polyethylene (HMWHDPE), Flooding Cubes are UV-stable, impact-resistant, and built to handle tough Aussie conditions. With a load capacity of 350 kg/m² and a working temperature range of -60°C to 80°C, they’re made for long-term use, with a lifespan of up to 15 years.
