Croudace Rapid response To create a rainwater disposal system under extremely wet conditions. Let's go! Client Croudace. Project Objective To create a rainwater disposal system under extremely wet conditions. Project Description: To prepare an attenuation system for this house builder’s large 600 luxury home development. The excavated hole on this site was to be lined and welded in-situ. Onto this lining 13,000 PolyStorm modules were stacked. The resulting 3000m³ structure was then wrapped and sealed by geomembrane with a geotextile protector and the entire unit connected into the existing storm water drainage system before being back-filled. Note that the PolyStorm modules have a good loading capability. Products involved Flexline 1.2 FPA geomembrane lining, with 300g/m² needle-punched geotextile wrap, around the PolyStorm modules. Outcome Installation with minimal disruption to the developer’s build schedule. Benefits Rapid response; high quality welding in extreme conditions.
