Envirocrate Stormwater Attenuation/Soakaway Shallow Crate
Stormwater crates are designed to store peak flow water discharge and release it slowly over a period of time or allow peak flow to soakaway.
Manufactured in the UK to ISO 9001 standards, these crates are made from recycled polypropylene and are fully recyclable at end of use.
The Stormwater Attenuation Crates have a stackable modular design which combine to form a subterranean water infiltration, storage and attenuation system. The required structure can be enclosed in a permeable geotextile membrane for soakaways or non permeable geomembrane (plus protective fleece) for attenuation systems.
The storm crates have a high void to volume ratio to maximise water storage, yet are robust and designed either for landscape and pedestrian loading or heavy loading to withstand all types of vehicular traffic. We supply crates for both pedestrian and vehicle traffic.
Benefits:
- Lightweight and robust
- High void-to-volume ration
- Easy to install
- Prevents extreme peak flows to mains drainage and water table
- Reduces risk of localised flooding
- Helps projects to comply with SUDS (Sustainable Urban Drainage Systems) requirements
- Geotextiles, geomembranes, top hats are available on request - please get in touch.
