PolyDrain PDX® combines the precision and accuracy of premanufactured polymer concrete with the design flexibility of cast-in-place construction. Our surface drainage systems are second to none. The built-to-order channel sections satisfy practically any custom layout, structural or hydraulic load, and chemical resistance demands. Concrete drainage channels also feature tongue and groove joints for positive alignment and an outstanding fit with any requisite joint sealant.
PDX is available in 7 different interior widths from 6” [152mm] up to 24” [609mm] with depth increments from 0.197” [5mm] up to 19.69” [500mm]. Channel slopes can also be adapted to fit any project with up to a 4% grade.
No-float U-Legs eliminate subgrade barrier penetration common with most competitors systems and the concrete anchoring slab holds the forming system firmly in place.
Adjustable Rail Clamp
The adjustable clamp allows the formwork to be micro-adjusted once the anchoring slab is poured over the bottom of the u-legs and prevents uneven joints.
Welded concrete studs independently anchor the frame into the surrounding concrete delivering structural load transfer and maximum service life.
With almost 100 grate options available, we can help you select a grate with the right size, strength, style, and corrosion resistance for your application.
Tongue and Goove Joints
High precision tongue and groove joints for positive alignment and superior joint with any requisite sealant.
PDX channels feature a numeric label to make installation easy and simple.
All PDX channels are available in two polymer concrete formulations. Both offer superior strength and durability over alternative materials. All PolyDrain Polyester channels are UL classified.
NFPA Codes and Trench Drain
Request a UL listed product
Various NFPA codes require surface drainage system components to be made of non-combustible materials. The intent of these codes is to prevent the spread of flame. Since trenches are collection points of flammable liquids and heavier than air vapors, trench drains can spread fire and contribute to smoke development even when empty. All ABT Inc’s Polyester Polymer Concrete products carry the UL 723 Classified mark for Class A fire rating for flame spread and smoke development.
PDX is the first and only versatile chemically resistant modular polymeric surface drainage channel system. The PDX system allows the designer or customer the ability to select the trench width, depth, and slope as hydraulically required. No longer do the limited manufacturers’ product offerings drive the design. PDX is available in 0% to 4% slope in .5% increments.
Channels – Manufactured from UL/ULC certified polymeric material, the channels feature a high precision tongue and groove joint for positive alignment and a superior configuration for sealant application. Available in 6″, 8″ 10″,12″,15″, 18″, 21″, and 24″ widths. All channels are 1 meter long.
Grate Options – A wide range of grate options exist for pedestrian to airport applications. Select grates with the right strength, style, and corrosion resistance for the application.
Frame Options – Steel, painted steel, galvanized steel, or FRP styles are available. Select the best rail material for your application. All rails are independently anchored into the surrounding concrete so that the encapsulation concrete receives the horizontal loads, not the channel walls.
Variable Grate Retention Systems – Toggle locks are available for low-speed horizontal loads. ABT can assist you in making a suitable selection.
