Our 5 cubic metre triple soakaway system comes flat-packed and with enough geotextile membrane to wrap all outer layers of the system.

You will need 15 triple crates which we would recommend laying 5 crates wide by 3 crates long. This will give you a complete soakaway of 2m (W) x 2.145m (L) x 1.28m (D).

A rubber mallet for assembly and a number of cable ties will also be included to join the crates together and to clamp the membrane around your pipe entry points.

Assembly of this set really is a quick and easy process.

Full instructions are included and you can view a quick video on assembling flat-packed soakaways below. For our triple crate, you just need to add another layer of small plates on top of the double crate as you do to convert the shallow into a double. 

Size, load and capacity

The dimensions of the complete soakaway are 2m (W) x 2.145m (L) x 1.28m (D)

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 5 cubic metre soakaway is an impressive 5,491 Litres.

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, pedestrian and low-speed traffic 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.

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 5m³ Soakaway Sets and these are used to connect two sides of the complete soakaway together in an L formation (the others are jammed into this corner). These ties are used purely to hold the crates in place until the sand or gravel side fill has been added.

Inspection & Cleaning

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.

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.

Flow Control with Attenuation

With the increase in emphasis on SuDS local planning authorities and specifiers are implementing flow control systems to prevent flooding. Through attenuation, rainwater is released back into the network, but in order to ensure you aren't passing any potential issues downstream this is done so at a controlled speed. Check out our Flow Controls page for more information about Orifice Chambers & Valves.

Connecting Pipes to Soakaways

The 110mm (or 160mm) drainage pipe is fed into the soakaway via the entry plate. 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.
