INNOVATIVE SUSTAINABLE DRAINAGE PRODUCTS AND SOLUTIONS
What Is Permavoid?
What?
Modular units with a 95% void ratio and ultra-shallow profile that form a monolithic stormwater control structure that reduces the impact of urban development.
Why?
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.
Where It Helps.
Permavoid helps reduce the costs associated with deep excavations, backfill materials, and potential subgrade conflicts including bedrock, contaminated ground, buried utilities, and high water tables.
