Drainage Sales sells both the Aquavoid and the Polypipe Polystorm Soakaway crate systems.
These cells, or crates as they are commonly known, are now the most commonly used method of building a soakway both in both domestic housing and commercial applications.
Soakaway Crates Features & Benefits
Soakaways 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). The Aquavoid Crates have a holding capacity of 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.
Soakaway Crates Compatibility
The crates are interlocking and have knockout sections along the side to accommodate the incoming pipes. For more details on these entry points please refer to the individual product pages.
Soakaways Crates Delivery
Please note that that due to their bulky nature orders for water crates incur an additional £10 delivery charge.
