Permavoid 400MD

INNOVATIVE SUSTAINABLE DRAINAGE PRODUCTS AND SOLUTIONS

Permavoid MD (PV400) structural cells are a water management solution designed for both stormwater quality and quantity. High-strength units capture large volumes of water and promote more natural stormwater behavior through infiltration, retention or detention.

Water quality is also enhanced within the system through patented Biomat filtration. The floating composite adsorbs hydrocarbons on the water's surface and allows microbes to naturally digest and eliminate the pollutant. Permavoid MD is suitable for many stormwater management applications ranging from high-speed, heavy duty traffic through landscape areas.
