Brett Martin’s StormCrates are geocellular components that are used as below surface water infiltration, filtering ground stormwater through attenuation tanks and systems.
How does an attenuation tank work? And what is an attenuation tank?
The StormCrates are designed to be stacked together, to enable the infiltration of stormwater or to make a structural below ground tank. The underground tank is created using the space created inside the attenuation tanks, filling it up with the excess stormwater. That act of rainwater harvesting is then soaked back into the ground water table or drainage system over a sustained time period.
These types of stormwater attenuation tanks have helped alleviate pressure on traditional surface water drainage systems consistent with the Sustainable Urban Drainage Systems (SUDS) program advocated by the Environment Agency.
- StormCrates provide a highly effective means of managing stormwater utilising underground attenuation tanks.
- Rainwater Infiltration: StormCrates should be wrapped in a geotextile that enables the rainwater harvesting to flow back into the water table and to slowly seep into the surrounding ground.
- StormCrates covered with an impermeable geomembrane can create a tank that is located underground. The outlet from this tank is controlled to facilitate a slow release of the water that was stored back.
QUICK & EASY TO INSTALL
- Weighing in at just 18kg per module, StormCrates can be lifted and put in place by hand.
- StormCrates are easy and quick to install as stormwater attenuation tanks in commercial, residential or industrial projects.
- Shallow installation depths: with only 250mm cover required above crates for loading and a 500mm cover required above crates for drive loading.
- The modules are combined using practical connectors, a method that permits crates to fit together quickly and without difficulty.
- Once set up the crates are available for inspection for future maintenance when used with StormCrate Inspect Crates (Inspect Crates available to special order).
- The modular character of StormCrates enable the attenuation tanks system to be scaled appropriately based on calculated runoff requirements. So, for example, 10 StormCrates shop 3m³ of stormwater. This helps create tank sizes that are appropriate to your storm water amount and drainage areas.
- The cellular structure of StormCrate maximises water holding capacities and every StormCrate has a capacity to store up to 300L or 0.3m³ of stormwater.
- LOAD BEARING
- StormCrate eases SLW 60-bearability using a 500mm (19.7″) covering, which represents a vehicle of up to 60t.
- The lorry bearing attenuation tank design can bear a long-term load of approximately 3.5t per m².
- The lorry bearing crate design ensures extreme load capacity thanks to StormCrates stable column arrangement.
- There are no limits on the surface over the UK soakaway crates system’s use and design. StormCrates may be successfully installed under parking areas, driveways and landscaped areas.
