Rainsmart Ellipse Soakaway Set Flat-Packed with Silt Trap & Lid 1 Cubic Metre

This soakaway set is comprised of four Rainsmart Ellipse Soakaway Crates (24.2-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 and a rubber mallet for easy assembly.

Additionally, the set contains a Sentinel Silt Trap (SS300110LID) to filter out sediments and allow a clean flow of water into the soakaway, as well as an A15 Cover.

The assembly of this set really is a quick and easy process taking around 10-12 minutes in total and the self-assembly set represents excellent value for money - it is around £30 plus VAT cheaper than the fully assembled option.

Full instructions are included and you can view a quick video on assembling flat-packed soakaways below.

The dimensions of the complete soakaway are 1430mm (L) x 800mm (W) x 860mm (D)

Load Rating and capacity (volume of water held)

Rainsmart 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 935 Litres. Under normal conditions, this would be sufficient to hold water from a roof area of approximately 50 square metres.

The vertical crush load capacity of 24.2 tonnes per square metre ensures that the Rainsmart Ellipse crates are safe to be used beneath gardens and pedestrian areas. The lateral crush load of 18 tonnes per square metre is the best of any type of soakaway crate currently available in the UK.

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.

The Sentinel Silt Trap system ensures the longevity of the soakaway system - removing 99% of the silt and sand that would potentially end up in the system from surface areas. 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.

All outward-facing crate surfaces of any soakaway should be wrapped in a 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

The 110mm (or 160mm) drainage pipe is fed into the soakaway via one of the four circular 160mm open entry points. 110mm pipes simply rest on the bottom of this opening and we recommend that the pipe is inserted approximately 300mm inside the crate. Geotextile membrane should be installed over the opening first and then a small cross should be cut in the membrane at the entry point with a sharp knife. Carefully peel back the membrane, insert the pipe and tape or clamp the membrane tightly around the outside of the pipe to stop the ingress of any soil particles.

Joining crates together

As all four crates making up the soakaway set have a pipe entry plate, you should ensure that the three that are not being used face inside the soakaway as opposed to facing outwards this makes it easier to wrap the geotextile around the outside of the structure. Pipe entry points do not affect the structural integrity of the soakaway in any way.
