AquaVoid modular attenuation crates manage excessive rainfall allowing surface water to be stored and gradually released back to the ground or drainage network. Attenuation and infiltration helps to control the level of surface water, especially in areas prone to flooding. Introducing a new and improved design for 2025, AquaVoid now boasts a stronger structure, better void ratio and standardised dimensions.

Manufactured from recycled polypropylene, the AquaVoid system comprises an interlocking modular cell design and can be stacked to create different void sizes. A geotextile removes debris from stormwater while the addition of a geomembrane enables water storage when required.
