Permavoid Geocellular Water Management System
Permavoid is a geocellular water management solution, designed to provide shallow water storage for attenuation, detention or soakaway/infiltration beneath the surface. The modular, geocellular system is designed and tested for use in place of a traditional aggregate sub-base improving reliability, storage volumes and providing a more sustainable solution to traditional methods. The Permavoid units are suitable for use as a stormwater attenuation and/or infiltration system.
The cell itself has a unique jointing mechanism, which means it has exceptional strength, providing an interlocking ‘raft’ that will support structural loads across the most heavily trafficked areas. Permavoid can be used directly below porous paving and drain asphalt surfaces as a source control technique, or below impermeable top surfaces in conjunction with a water treatment system such as Permachannel.
Suitable for a number of applications, the National Bank of Oman used the Permavoid water management system for the podium deck of their impressive new headquarters in Muscat. Engineering a geocellular, green infrastructure solution that could be completed in just a few days, Polypipe’s technical experts undertook regular site visits during the installation phase to offer advice and ensure a right-first-time installation.
