  • TrenchFormer TFX

    Original Cast-In-Place Forming System

    TrenchFormer is the original expanded concrete cast-in-place channel drain forming system. Completely customizable forming sections allow designers to select the width, depth, shape, and slope for any specification and project conditions. The resultant high precision monolithic trench is faster and easier to install when compared to traditional hand-formed cast-in-place trenches.

    Significantly, the concrete former is entirely removed prior to service allowing complete inspection of the workmanship and quality of the final product. Other systems conceal concrete voids, which could lead to frame collapse and other failures.

  • 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.

  • Paver Grate

    Discreet Drainage CHANNEL For Architectural Pavers

    PolyDrain PaverGrate® is a discrete slot drain system designed to provide a nearly invisible surface drain option when used in conjunction with brick or stone pavers.

    With a 5/16″ (7.9mm) opening, PaverGrate® is both ADA and Heel Proof.

  • PolyDrain Shallow

    Economical Polymer Concrete Channels

    When performance matters on your project, our PolyDrain® Shallow polymer concrete drainage channels offer a practical and economical drainage solution. The initial cost of plastic and fiberglass trench drain may look attractive; however, the different thermal expansion coefficients between dissimilar materials and surrounding concrete repeatedly introduce extreme thermal stresses. These stresses can lead to fracture or deformation of the drainage channels. Most fiberglass and plastic materials are also extremely susceptible to UV degradation.

    Under serviceable design loads and proper installation, polymer concrete can often outlast the life of the concrete slab. This superior quality makes our shallow-depth polymer concrete drainage channels top-of-the-line.

  • VectorDrain®

    Economical Slot Drain

    VectorDrain® is an ADA compliant slot drain channel with a narrow profile and clean lines using an underground PVC system for drainage. The polymer concrete inlet will also withstand harsh environments that often destroy plastic drain inlents. Thanks to its hidden PVC pipe drainage system, VectorDrain® is a smart and cost-effective solution for a wide variety of drainage situations and capable of handling the heaviest pedestrian traffic.

    The polymer concrete top also bonds with most concrete surface coatings and will create an unmatched, virtually invisible, finished appearance. Thus, VectorDrain® is the ideal slot drain for patios, pool decks, running tracks, sidewalks, and pavilions.

  • Interceptor® A-67

    The Original Highway Drainage System

    We developed Interceptor® roadway trench drain system in collaboration with numerous state departments of transportation to address the common and long-standing challenges of roadway drainage. Interceptor® A-67 roadway trench drain systems limit the excessive spread and dangerous hydroplaning conditions where standing water, sheet flow, and inlet bypass problems exist. Our Interceptor® polymer concrete roadway trench drain systems include advanced integral frames and grates, which can withstand high-speed highway traffic and snowplow blades. Equally important, common trench obstructions are cleared through the grates with conventional high-pressure wash equipment and trucks.

    The performance and technical design of the Interceptor® A-67 highway drainage system has set the standard for Transportation Departments in North America.

  • 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.

  • Interceptor® SuperSlope

    Point Inlet Refinement

    The Interceptor® SuperSlope high-volume sloped drainage channel augments the advantages of PDX with our integral frame and grate. SuperSlope is the perfect interceptor drain system for applications that require traversing more extreme grades or where extra inflow capacity is needed. In a sump location, flanking inlet structures with SuperSlope have been shown to limit inlet bypass and reduce cost by reducing the number of structures needed.

    For over 30 years, ABT's skilled team has made it our top priority to provide outstanding service and top-of-the-line drain solutions. Our Interceptor sloped highway drain systems and other drainage products are uniquely designed using materials of the highest standard.

    We take pride in the fact that we manufacture some of the most extensive, reliable, and versatile lines of channel drains, grates, and water management solutions in the road and highway industry.

  • 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 in the only maintenance required.

  • Sandtrap

    Modular Sediment and Debris Interceptors

    Sand trap in-line catch basins remove sand and other pollutant debris from any connected drainage system. During storm events, our gravity separation method captures both sediment and buoyant materials. It is also a 100% natural process with low operating costs and no chemicals that might cause environmental concerns.

    These pre-cast modular catch basin interceptors are reliable, efficient water filtration solutions. Use them to prevent clogs and keep downstream waterways and storm-water systems clean of contaminants.
