40%? Really?

Reliable Storage

Let's stop kidding ourselves.  40% stone void space is optimistic, even in a lab.  Fines migrate, fabrics clogs, and designs fail.  Voidsaver only uses the stone when absolutely necessary, providing the most efficient and reliable design. 

Treatment, Maintenance & LID

Rely on Voidsaver's patent pending design for low-cost internal stormwater treatment, easy access, fast inspection, and trouble-free maintenance.  It can even be used for rainwater harvesting.
