Sub-surface stormwater crates designed to clear surface water quickly and manage runoff sustainably, the Polystorm PolyPipe Storm Crate aims to reduce pooling and protect landscaped areas. Homeowners and contractors gain reassurance from a solution built for long-term performance. Does the system suit your site conditions and installation plan?
⚡ At a Glance
- • Drainage Performance: Rapid diversion of surface water into interconnected crates, with 3D flow channels and integrated inlet and outlet
- • Best for: Landscaping projects, driveways and small attenuation schemes requiring reliable infiltration or retention
- • Not ideal for: Sites needing active pumping, pressurised discharge or specialised filtration beyond geotextile protection
Modular crates channel surface water into a high-void internal volume for quick infiltration. BBA approval and a 60-year creep limited life expectancy indicate suitability for long-term drainage schemes.
Clears Surface Water Quickly - thanks to integrated inlet, outlet and 3D flow
Integrated inlet and outlet channels feed runoff into internal 3D flow paths so water moves through the crate network and soaks into lower ground rather than pooling on the surface.
Surface puddles dissipate faster, reducing local flood risk and keeping lawns, paths and driveways usable after heavy rain.
High Load-Bearing and Durability - thanks to 61 tonnes per square metre compression strength
A reinforced ribbed structure, made from selected recycled polymer, provides tested compression resistance of 61 tonnes/m2 to limit deformation under load.
Suitable for installations beneath trafficked areas such as access roads or car parks while maintaining structural integrity over time.
Efficient Water Storage with Minimal Footprint - thanks to a 95% void ratio and modular design
A 95% void ratio means most internal volume stores water, and interlocking crate geometry creates continuous storage for infiltration, retention or attenuation applications.
Allows compact attenuation basins or soakaways that use fewer units and simplify on-site layout when paired with the recommended geotextile membrane.

❓ Frequently Asked Questions
Q: What are Polystorm PolyPipe Storm Crates used for?
A: They divert surface water into internal storage so runoff soaks down into lower ground, clearing water quickly from surfaces such as lawns, driveways and landscaped areas.
Q: Do I need a geotextile membrane with the crates?
A: Use with a suitable geotextile weed membrane for infiltration, retention or attenuation; a 100gsm membrane is recommended, roughly 2.25 sqm per crate if chosen.
Q: How durable are the crates under load?
A: Compression strength is rated at 61 tonnes per square metre and the product is BBA approved with a 60-year creep limited life expectancy, indicating long-term structural performance.
🏆 Our Verdict
The Polystorm PolyPipe Storm Crate suits landscapers, groundworkers and homeowners needing reliable sub-surface drainage and attenuation. High void ratio combined with robust compression strength and BBA approval make it a dependable choice for long-term schemes. While the initial outlay requires planning, longevity and recycled-material construction deliver strong value over time.
