Permavoid is an innovative, multi-functional stormwater management system designed to revolutionize urban development drainage by treating stormwater as a valuable resource rather than waste. This cutting-edge system comprises modular units with a 95% void ratio and an ultra-shallow profile, which combine to form a monolithic stormwater control structure that mitigates the effects of urban development. Furthermore, its high-strength polypropylene raft is perfect for replacing traditional subbase, deep conveyance pipes, and water detention structures, thus reducing costs and complications associated with deep excavations, backfill materials, and potential subgrade conflicts.
The benefits of Permavoid stem from its emphasis on functionality and sustainability. As an efficient water storage and stormwater management solution, it maximizes utility while minimizing waste. The ABT Permavoid system is a modular, interlocking plastic structure made from a robust co-polymer polypropylene material, which grants it exceptional compressive strength. Its proprietary jointing system ensures maximum bending resistance, creating a horizontal structural 'raft' within the pavement that effectively dissipates heavy traffic loads, even on poor subgrade soils. The PV-150 and PV-85 variants of Permavoid provide comprehensive stormwater management, offering conveyance, detention, and LID source control within an ultra-shallow envelope. This advanced system not only addresses modern stormwater management challenges but also supports sustainable urban development practices.
