When it came to the management and control of surface water run-off at a caravan showground in Hull, StormCrate55, an engineered Sustainable Drainage System (SuDS) was up for the challenge.
The static caravan manufacturer’s facility features a newly refurbished showground where customers can view a huge range of homes. Having previously used Stormcrate55 to successfully manage stormwater on a number of other projects, installer Catalogue Engineering undertook the installation for groundworks contractor Evabuild in order to reduce the risk of flooding on this trafficked site during periods of heavy rainfall.
The StormCrate55 modular units were clipped together in a brick bond pattern to create a three tiered underground attenuation tank on site which has now been tarmacked over. With a loading capability of 562kN per m³, their high strength provided more than enough vertical strength for this area of the showground. For the installation team, the lightweight crates were easy to handle and fit together making the task on site a straightforward installation.
On this project, the StormCrate55 system was surrounded with an impermeable membrane to create a sealed underground tank. The outlet from this tank is then controlled to facilitate a slow release of the stored water back into the drainage system over a longer period.
