PERMAVOID INNOVATIVE DRAINAGE SYSTEMS
INNOVATIVE SUSTAINABLE DRAINAGE PRODUCTS AND SOLUTIONS
Permavoid is a multi-functional stormwater management system engineered to create functional and appealing site drainage which treats stormwater as a resource, rather than a waste product.
Modular units with a 95% void ratio and ultra-shallow profile form a monolithic stormwater control structure that reduces the impact of urban development. Our designs and sustainable drainage products cultivate the natural movement of water within the local ecosystem and watershed. The high-strength polypropylene raft is also ideal for subbase, deep conveyance pipe, and water detention replacement. Eliminating traditional conveyance structures reduces the costs associated with deep excavations, backfill materials, and potential subgrade conflicts including bedrock, contaminated ground, buried utilities, and high water tables.
