DURA SLOPE™
An economical alternative to traditional heavy concrete trench drain systems. Dura Slope™ won’t break like concrete if dropped, yet it’s much lighter. Dura Slope™ channels may be cut to any length with hand tools. Its light weight means it is easier to load, unload, and carry. And it doesn’t over-burden vehicles like heavy polymer concrete. Fast and easy to assemble—most jobs can be laid out and poured the same day. Channel sections simply snap together. Integral re-bar supports are designed to grip #3 or #4 re-bar (3/8" – 1/2") for easier channel height adjustment during installation. And exclusive DuraLoc™ tongue-and-groove ends snap-lock into place, making precise fit and straight channel runs easy. Applications include driveways, parking areas, warehouses, loading docks, gas station entrances, and other areas for the interception and collection of surface run-off.

Polycast
Precast concrete drains are an improved method of installing drainage systems in concrete slabs. Each channel has built-in 0.65% slope that simplifies installation and guarantees efficient drainage. Precast components eliminate complicated formwork. Just assemble the components inside a prepared excavation and pour the slab. Installation time and labor is a fraction of that required to form a cast-in-place drainage system. Precast channels are made of high strength polymer concrete that resists damage from freeze/thaw and exposure to a wide range of chemicals. The extremely smooth, rounded surface provides maximum liquid flow. All channels come complete with either galvanized steel (light load) or cast iron (medium load) gratings. Standard channel length is 48". A wide selection of grates is available to handle any situation. For general usage, galvanized steel is standard. The cast iron grate is ideal for medium traffic areas. The fiberglass grate is highly resistant to corrosives. Stainless steel is available for food processing areas. Drainage channels are supplied complete with the specified grate. The system also includes catch basins with removable trash buckets. All channels are numbered and have arrows indicating the flow direction. This versatile system is economical, durable and easy to install. It provides an ideal solution to almost any surface drainage problem. A reinforced frame system is required to resist heavy loads on slabs where hard wheeled traffic is anticipated. Call Masons for more information on your load requirements and chemical resistance.
