Stormwater attenuation

Stormwater attenuation crates are high-capacity storage systems that temporarily hold excess rainfall runoff and release it at a controlled rate. This protects downstream drainage networks and reduces flooding risk on your development. Our crates feature a 95-96% percent void ratio, meaning they store far more water than their physical footprint suggests.

They are load-bearing up to 60 tonnes, so they can be installed beneath car parks, roads, and landscaped areas without additional structural support. Installation is quick and easy, with a design that prioritises easy transportation to the site and rapid deployment. The crates are custom-designed to match the specific requirements of your site, including difficult or hard-to-access areas where traditional attenuation ponds or tanks cannot be fitted. With a 50-year design life, they provide long-term, reliable surface water management for Irish developments.
