This soakaway set is comprised of four Rainsmart Heavy Soakaway Crates (65 tonne vertical load capacity) and sufficient non-woven geotextile membrane to wrap all outward faces of the soakaway including the base. The set also includes cable ties for holding the crates together until the side fill has been introduced.

Our Rainsmart 65 Tonne Soakaway sets are also available flat-packed for space saving and quick assembly on-site - if you are working to a tight budget this is an excellent option as assembly of the whole set only takes apporximately 12 minutes and there is a cost saving of £30 + VAT.  Cick here to watch a video on crate assembly.

Size, load and capacity

The dimensions of the complete soakaway are 1200mm (L) x 1200mm (W) x 690mm (D)

Rainsmart 65 Tonne soakaway crates have a void ratio of 95% - this is the amount of free space within the crate structure that can be used for rainwater storage. The capacity of this 1 cubic metre soakaway is an impressive 943 Litres. This is far superior to traditional hardcore style soakaways. Under normal conditions this would be sufficient to hold water from a roof area of approximately 50 square metres.

The high load carrying ability of the Rainsmart Heavy crate system (vertical crush capacity 65 tonnes per square metre) makes it the ideal system ideal for use in load applications in new housing development, commercial and infrastructure projects.

Manufacture and useful life

Prime quality polymer is used to manufacture the STM-02 65 tonne crate system. The system is unaffected by chemicals and bacteria commonly found in uncontaminated soils and stormwater runoff.

When installed as per Rainsmart Installation guidelines, and within the stipulated design parameters, the system has a design life in excess of 50 years.

Joining crates together

Clips are not required to hold the crates together. No clips on any crate system are structural it is always the side fill on any soakaway installation which adds the stability needed to hold the structure in place.  Cable Ties are included with our 1m³ Soakaway Sets and these are used purely to hold the crates in place until the sand or gravel side fill has been added.

All outward facing crate surfaces of any soakaway should be wrapped in non-woven geotextile membrane, which allows the free passage of water but prevents any soil or sand particles from entering the soakaway, maintaining its long term efficiency.

Connecting Pipes to Soakaways

Rainwater is fed into the soakaway by butting the open end of the stormwater pipe against one of the crates. Geotextile membrane should be laid over the crates first and then a small cross should be cut in the membrane where it meets the pipe. Fold the membrane back and clamp it around the outside edge of the pipe, which is supported by the side fill. For extra stability if required a weak concrete mix can be be poured around the end of the pipe where it meets the crate.

Consider a pre-filter

For best practice we always recommend that a pre-filter such as our Sentinel Silt Trap is used in conjunction with any modular soakaway system.  Emptying the filter on a regular basis (this is only a five minute job) will maintain the efficiency of the soakaway and greatly increase its lifespan.
