Stormwater crates are modular plastic water cells designed to mimic a natural soakaway — providing an efficient, sustainable way to manage surface water and reduce flooding risk.
Why Are They Popular?
Used in both commercial and domestic projects, stormwater crates offer a simple, cost-effective and easy-to-install solution for managing surface water and preventing flooding. Their growing popularity is driven by increased awareness of environmental sustainability and the introduction of tighter water management legislation.
Soakaway crates have become a standard component in modern construction projects — widely used by local authorities, developers, and homeowners alike to meet sustainable drainage (SuDS) requirements.
How Do They Work?
Traditional soakaways are simple pits filled with gravel or stones, but stormwater crates take this concept further. Made from high-strength recycled plastic, these modular crates clip together to form an underground chamber that stores rainwater temporarily before slowly releasing it into the ground.
Installed below ground, stormwater crates manage the flow of surface water during heavy rainfall. With up to 97% void capacity, they store significant volumes of water and release it gradually — preventing flash flooding and reducing strain on drainage systems.
