Soakaway Crates
Up to 40 years design life

    Mainly made of high purity PP with features of fragile and tough. Our polystorm soakaway crates doesn’t react easily with acid or vinegar, etc. Owning to provide an environment at cryogenic temperatures by applicating underground, the underground stormwater crates' serving life could be above 40 years. And they are 100% recyclable at the end of it useful life.
    By the reason of making full use of dynamics and logistic principles, stability of triangle are applicated a lot on its plates. With the combination of round shape, the Drainage System is proven to provide robust, effective source control through retention, storage and collection at deeper or shallower depths.
    PP Soakaway Crates enormous void percentage, 95%, enables the ability to create a larger subterranean cavity utilizing less space. The result is a reduction in excavation and land clearing requirements. The stormwater management system can store an unlimited amount of water and control stormwater runoff.
Soakaway Crates for Drainage System

Stormwater Retention, Attenuation and Infiltration
The underground stormwater crates can be mainly used for rainwater Retention, Attenuation, Infiltration. The drainage system and water storage-permeation and filtration system along side the roads, parking lot, water storage and drainage for the ecological shallow ridges, living community, factories and enterprises, municipal roads, viaducts and bridges, park and scenic spot, it will be the necessity for construction of sponge city.

The structure characteristics of Soakaway Crates

High Void Ratio  - 96% void ratio providing greater water storage capacity with reduced excavation and disposal costs.
High Compression Load  - Resisting stretch and extrusion by fully utilizing triangle’s stability and round shape. (reach 77106 lb)
Unique Columnar Construction  - Adopt cylinder-shaped construction, suitable for non-trafficked, trafficked or heavily trafficked appilication.
Structural integration  - Distributing the loaded weight on to all the plates, fully utilized the effect of each plate.
Stable Design  - Interlocks vertically and horizontally for maximum stability, avoid the whole system from floating.
Fast Installation  - The built-in socket and ports bring extremely convenience of quick installation(about 30 seconds for 1 CBM installation).
