How it works – Geocell Soakaway Crates:
Stormwater enters the plastic soakaway crates attenuation tank through the inlet pipe, which could optionally include a silt trap with silt bucket (sold separately). Water passes through the tank and exits into the ground around it releasing the water slowly stopping flooding. The tank is wrapped in a non-woven goetextile. Non woven is used because it allows water to pass through it. Please do not use woven membranes with these kind of system as they do not efficiently release the water. The membrane stops any dirt getting into the system which would reduce it’s effectiveness.
Don’t forget to perform a percolation test prior to installation. We have a guide in our blog section detailing how to do this. This will ensure that the ground is suitable and is able to release the water effectively.
Soakaway:
The soakaway is normally best constructed as a long narrow structure. The inlet pipe comes in at roof level and faces downwards so the water can percolate into the tank. The blocks are wrapped in Geotextile, to protect them and to keep clay from filling up the empty space. An air vent pipe is installed on the maximum height point with a cowl at the top or it can be vented back into an inlet manhole. There’s no outlet from a soakaway, therefore no flow control unit is required.
Benefits:
● 100% sealed tank
● 12 years experience as a market leader
● Quick installation – reduce site access delays
● Increased land usage – tanks are subsurface
● Economical – generally more cost-efficient than any other equivalent sealed tank
● Cost-effective – reduced costs for excavation and disposal of the material
● Modular – easy to create any shape
● Strong – designed to support shear loading
● Lightweight – no cranes required
● Determinate volume – one cubic metre of matrix tank modules contain 950 litres of water, whereas stone fill will only provide 300 litres of storage per cubic metre.
Design Criteria:
The soakaway attenuation tank is assembled using matrix module blocks. These blocks can take passing loads of up to 40 tonnes/m2. The void ratio of every block is 95%. The soakaway crates are made from polypropylene. The tank is sealed with a layer of geotextile membrane, which is completely welded together to make a 100 percent seal. All pipe penetrations should be fully sealed into the geotextile membrane. The membrane is shielded by a layer of heavy-duty protection geotextile, to prevent damage from construction or backfilling. A range of air extraction vents/flushing points are then placed in the roof of the tank.
Note:
It’s crucial that the underground tanks are totally sealed, otherwise soil water and silt particles can enter the void space and consume capacity. Preferably, the bottom of the tank must be 500mm above the groundwater level. Otherwise, floor water relief measures must be put into place.

Would be easier if the dimensions height and width were the same. They differ by about 2cm. Otherwise good size easy to handle.

Kits need to cable tied together but the smaller size helped provide flexibility as had done 2 different soakaway sizes. Slightly longer cable ties would be my only request but all good otherwise. Really pleased.

These seem to be pretty good, I’ve never seen the crates before in person, so not an authority on this. But they are pretty solid, they don’t come flat packed. The fabric is very thick, the tape is ducktape type and some zip ties were included. It was all delivered on a pallet. They were more rectangular shaped than some other brands, so we had to dig our hole wider, but I’m happy with these.
