1)ULTRA-SHALLOW PROFILE– The ultra-shallow profile promotes stormwater infiltration over the largest area possible, including under traditional and permeable pavements.
2)SHEAR CONNECTOR– Shear connectors prevent the modular units on top of each other from shifting or sliding sideways, creating a stable stack.
3)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.
4)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.
Permavoid innovative drainage systems are designed with functionality and sustainability in mind. Permavoid irrigation system is ideal for efficient water storage and stormwater management, with high-functionality and zero waste.
ABT Permavoid is a modular interlocking plastic system designed for use as a combined drainage component and sub-base replacement. The system has exceptionally high compressive strength due to it’s engineered co-polymer polypropylene structure. The proprietary jointing system provides maximum bending resistance creating a horizontal structural ‘raft’ within the pavement allowing for the dissipation of heavy traffic loads to even poor subgrade soils. Both PV-150 and PV-85 are ideally suited to provide conveyance, detention and LID source control of stormwater all within an ultra-shallow envelope.
We strive to provide high-quality products and solutions to solve any type of water management challenges. With years of experience and dedication to our work, we bring you the best customer service and all-around satisfaction.
