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.
