Polystorm Soakaway Crate Heavy Duty (20 Tonne).

The volume of each crate is 0.2m per cube. Therefore you will need 5x crates to cover 1 cubic metre. Each crate comes with 4 clips for joining horizontally and 2 shear connectors for joining vertically.

Polystorm features individual modular cells that can be built up to form a load-bearing tank structure of any shape or size to receive rainwater collected from the gutter system or surface drains ready to release within a set discharge limit. Polystorm has a 40 tonne per square metre compressive strength and is ideally suited for light trafficked and loaded applications. Polystorm can be used for both attenuation and soakaway applications and typically for housing developments, small car parks and light commercial developments.
