Permavoid

Innovative Sustainable Drainage Products and Solutions

Permavoid is a multi-functional stormwater management system engineered to create functional and appealing urban development drainage which treats stormwater as a resource, rather than a waste product.

Modular units with a 95% void ratio and ultra-shallow profile form a monolithic stormwater control structure that reduces the impact of urban development. Our designs and sustainable drainage products cultivate the natural movement of water within the local ecosystem and watershed. The high-strength polypropylene raft is also ideal for subbase, deep conveyance pipe, and water detention replacement. Eliminating traditional conveyance structures reduces the costs associated with deep excavations, backfill materials, and potential subgrade conflicts including bedrock, contaminated ground, buried utilities, and high water tables.

Permavoid innovative stormwater management 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 its 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.

Design Software

Permavoid can be easily modeled with the HydroCAD Stormwater Modeling system, allowing simplified analysis of its behavior in a drainage and stormwater management system. HydroCAD includes custom rating curves for these devices, which can be used with the “special outlet” capability to easily define its stage-discharge characteristics. Click here for details.
