Drainage Sales sells Aquavoid, Polystorm and Polystorm Lite lightweight modular water storage cells. These cells, or crates as they are commonly known, are now the most popular way to create soakways in residential and commercial applications. They are a step forward in drainage technology, doing away with old fashioned, inefficient soakaways filled with hardcore and building waste and providing a safe and intelligent solution to rainwater management.
Each individual Polystorm water crate can hold 190 litres of water (0.19 cubic meters). Our Aquavoid Crates hold 333 litres (0.333 cubic metres).
The outward facing surfaces of the crates should be wrapped in geotextile membrane
to stop soil from entering and clogging up the system.
In order to form a 1 cubic metre soakaway (1m square x 1m deep) you would need 5 Polystorm crates, or 3 Aquavoid Crates. This would be sufficient to drain an average roof area of 50sq metres.
The crates are interlocking and have knockout sections along the side to accommodate the incoming pipes.
Please note that that due to their bulky nature orders for water crates incur an additional £10 delivery charge.
Installation instructions for our aquavoid and Polystorm water crates are available on request.
