The RainSmart modules are placed underground to provide a tank system that is used to hold water (detention system), soak water away (infiltration system) or detain water and release at a controlled rate (attenuation system).
The tanks are 715mm long x 400mm wide and are available in various heights – single units (0.44m), double (0.86m), triple (1.28m), quad (1.7m) or penta (2.12m). Penta (five tanks high) is the maximum height without getting site-specific engineering.
They are placed in an excavated hole and wrapped with DuraForce™ geotextile. If they need to hold water, not soak away, they are also bound with an impermeable liner. The tank system is then covered with suitable backfill. We have detailed plans and instructions for installation available, please contact us.
RainSmart tanks are suited to trafficable and non-trafficable applications and provide significant void space. Systems installed with linear access pipes are simple to maintain.
300mm of cover material is needed for non-trafficable applications. Trafficable areas require 600mm of cover with a DuraGrid/SecuGrid®* geogrid installed 300mm above the tanks and extended 1.5m horizontally beyond the edge of the tank system. Please contact Cirtex if your site requires more than 1.5m of cover.
