What is a Polystorm soakaway?
Polystorm-R has been designed to provide surface water retention, surface water attenuation or surface water infiltration as a soakaway solution at a variety of depths in trafficked and loaded areas. It has a 61 tonnes/m² compressive strength and is manufactured from over 90% recycled material content.

What is Geocellular?
Description. Geocellular systems can be used to control and manage rainwater surface water runoff either as a soakaway or as a storage tank. The modular/honeycomb nature of geocellular systems means that they can be tailored to suit the specific requirements of any site.
What does an attenuation tank do?
An Attenuation Tank is essentially a large container/detention tank acting as a buffer to store excess rainwater and remove the risk of flooding of a residential area in a controlled way. Excess rainwater detained in a stormwater tank is then released at a controlled rate by a hydrobrake.
What are attenuation crates?
Attenuation crates, also known as soakaway crates, are used to control the level of surface water and reduce the risk of flooding. They are modular, so multiple crates can be used for a soakaway system capable of providing the desired flow rate of water to a body of water or drain.
How do I install attenuation crates?
Follow these 6 simple steps to install soakaway crates – both quickly and correctly:
- Step 1 – Create space.
- Step 2 – Prepare the crates.
- Step 3 – Prepare the base.
- Step 4 – Hook up to the drainage system.
- Step 5 – Cover the crates.
- Step 6 – Replace any ground that was removed.
What is an attenuation basin?
A detention basin (stormwater attenuation lagoon) prevents flooding by controlling the amount of stormwater that is released into the environment at any given time. When a storm event occurs, the detention pond simply fills up and stores large volumes of rainwater temporarily.
How do attenuation crates work?
Attenuation Tank Crates Stormwater attenuation tanks provide a storage system for rainwater & surface water. The stored water inside the attenuation tank is released via a flow-control chamber and either pumped via a pumping chamber or run-off through a gravity stormwater pipe system.
How do water retention tanks work?
Basically, a detention tank slows down how fast the rain off your roof gets into the stormwater under the streets. In newer areas, the stormwater drains have been engineered to allow for the rainwater run-off from the whole street.
Are soakaway crates any good?
Soakaway crates are often forgotten about or not considered, but they can be incredibly useful and worthwhile in reducing surface water, and minimising the amount of strain placed on drainage systems.
What are soakaway crates?
Soakaway crates act as a more advanced form of an old-fashioned ditch or pit. These were traditionally filled with gravel and used as a place for storm water and excess surface water to soak into.
Can a soakaway get blocked?
Can a soakaway get blocked? The main problem people experience with soakaways is that they can become blocked up with silt, leaves etc which have washed into the soakaway and can prevent the rain water being collected and percolated back into the soil.
