Permavoid 150

INNOVATIVE SUSTAINABLE DRAINAGE PRODUCTS AND SOLUTIONS

Permavoid 150 (PV150) structural cells are multi-functional water management solutions that promote sustainable stormwater behavior. The interconnected, high-strength units create a patented subbase replacement system that attenuates stormwater flows and, when feasible, promotes infiltration even beneath impervious surfaces. Units can be stacked to

create multi-layer tanks to fit nearly any site constraints while eliminating the need for traditional conveyance schemes. Permavoid systems can also enhance landscape resiliency through patented capillary cylinders that wick stormwater up toward vegetation without the need for sprinklers, pumps or energy to create the ultimate low impact solution.

Ultra-Shallow Profile Shear Connector Structural Subbase Source Control

Ultra-Shallow Profile

The ultra-shallow profile promotes stormwater infiltration over the largest area possible, including under traditional and permeable pavements.

Shear Connector

Shear connectors prevent the modular units on top of each other from shifting or sliding sideways, creating a stable stack.

Structural Subbase

The ultra-high-strength (104 psi yield) safely and reliably transfers traffic loads to subgrade soils replacing large volumes of hauled subbase stone.

Source Control

Modular units with 95% void ratio interlock with patented lateral connectors to create a monolithic stormwater management system eliminating the need for an end of line pond and tank.
