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. -
PolyDrain FirstFlush®
Stormwater Filtration for Urban Runoff
The "first flush effect" refers to the initial surface runoff during a rainstorm and the resulting surge of concentrated water pollution. Corresponding high sheet flows wash the pollutants through storm sewers to local surface waters. Our engineers created a Best Management Practice (BMP) to counter the negative effects of urban runoff.

Any storm runoff filtration system will collect debris, capture hydrocarbons, and should reduce pollutants. Our PolyDrain stormwater filtration solution also manages the significant overland flow during initial runoff events. We prioritize the stormwater first flush treatment event by allowing prolonged rainfall to bypass the treatment media. This bypass minimizes pulsing and prevents concentrated pollutants from the "first flush effect" from continuing on to downstream waterways.
FirstFlush® is the perfect sustainable drainage solution to meet this critical stormwater filtration challenge. -
Stormwater Channel Filter
Stormwater Filtration for Urban Runoff
The "first flush effect" refers to the initial surface runoff during a rainstorm and the resulting surge of concentrated water pollution. Corresponding high sheet flows wash the pollutants through storm sewers to local surface waters. Our engineers created a Best Management Practice (BMP) to counter the negative effects of urban runoff.

Any cast-in-place stormwater filtration system will collect debris, capture hydrocarbons, and should reduce pollutants. Our cast-in-place stormwater sustainable drainage and filtration products and solutions also manage the significant overland flow during initial runoff events. We prioritize the treatment of a first flush event by allowing prolonged rainfall to bypass the treatment media. This bypass minimizes pulsing and prevents concentrated pollutants from the "first flush effect" from continuing on to downstream waterways.
FirstFlush® is the perfect solution to meet this critical stormwater filtration challenge. -
Oil-Water Separator
Gravimetric Pre-Treatment Tank
TrenchFormer is uniquely positioned to collect non-point source (NPS) pollution from urban runoff. Our cast-in-place trench drain Oil-Water Separator is a cost-effective addition that separates these urban pollutants into their discrete components. Using a baffle plate, stand-pipe assembly, and gravity, our system separates oil, water, and solid particles from the site’s wastewater.

Uniquely, the TrenchFormer concrete Oil-Water Separator tank is constructed using a lightweight cast-in-place forming system that installs without the necessity of heavy equipment. The basic system contains no moving parts. Periodic removal of captured oil and solids is the only maintenance required.
