The Dura Trench family of trench drain products were designed for heavy duty commercial and industrial use.  These commercial channel drains are engineered with the best available technology.  The precast heavy duty trench drain systems are manufactured using our proprietary durable fiber reinforced polymer concrete.  The trench drain channels typically come in 8 foot or longer sections for fewer joints.  Thie makes the trench drain installation faster than other systems on the market.  This speed of installation is critical in commercial and industrial trench drain projects to keep labor costs to a minimum.  Dura Trench commercial trench drain systems also come fully assembled.  Unskilled labor can easily figure out how to install our heavy duty trench drain systems.  The trench drain body comes with a 2" overlap bell to make sealing the joints watertight much easier than with other trench drain systems.  This is critical for commercial trench drain applications where a plumbing code will require a watertight trench drain.  Our commercial duty channel drains are lighter weight so that one person can easily lift and set an 8ft piece in place without breaking OSHA rules.  Many other commercial precast trench drain systems are much heavier and their channel drains take two or more people to lift and set in place according to OSHA regulations.

The unique design of the Dura trench drain system allows us to offer standard trench drain sizes as follows: 2" trench drain, 4" trench drain, 6" trench drain, 8" trench drain, 10" trench drain, 12" trench drain, 18" trench drain, 24" trench drain, 36" trench drain, and 48" trench drain.  Dura Trench drain systems can also be manufactured in any slope.  Our channel drain manufacturing process allows the customer to get the exact flow and velocity they need inside the channel drain.  Our commercial channel drains can also be outfitted with any size and type of outlet pipe.  We cast any type of pipe fitting directly into the sidewall, end, or bottom of our trench drain systems.  This means that there are less pieces and faster installation of our channel drains.  Our trench drain bodies can also be manufactured with a rectangular or radius bottom.  A trench drain with a radius bottom offers better cleaning velocities reducing maintenance of the channel drain.  A rectangular bottom trench drain is often selected for above grade commercial applications where the channel drain is used in a shallow depth application.  Our shallow trench drains can be outfitted with clamping collars to receive waterproofing membranes.  Dura Trench drain systems with rectangular bottoms are also used in industrial and commercial applications where customers may want to clean the channel drain with a flat shovel.

The durability of our heavy duty trench drain systems is a result of years of studying why trench drains fail on commercial sites and inside of industrial factories.  We observed that most heavy duty trench drain failures are not due to channel drain grating or even improper installation of the trench drain system.  Most commercial channel drains fail because they do not properly transfer the loading through the top of the trench drain system.  The wheel loads must be properly transferred through the channel drain grating, into the channel drain frame, and finally into the surrounding concrete.  If any of the components of a heavy duty trench drain system fail, then the channel drain is compromised.  Dura Trench drain systems are designed for the commercial and industrial environment to provide proper load transfer from the channel drain grate into the load bearing frame.  Many "commercial" channel drain systems transfer this load directly into the channel drain wall.  The wall of a typical trench drain body has little load transfer ability.  This is why the heavy duty Dura Trench drain system has a frame that accepts this load and transfers it to the surrounding concrete.  Our commercial and industrial trench drain frames are offered in a wide variety of materials and finishes to fit any application.  We never compromise on the proper load transfer of the load applied to the trench drain.  This ensures that we can handle the heavy duty loads that you demand from a trench drain.  

Dura Trench drain systems have a long track record in applications such as airports, breweries, wineries, truck docks, gas stations, animal hospitals, kennels, industrial and manufacturing, sea ports, inter-modal facilities, food and beverage facilities, roadways, fountains, parks, patios, pavilions, pools, splash pads, fire stations, aquatic facilities, sports complexes, and the list goes on.  When you need a high quality trench drain system choose Dura Trench channel drains for your next project.
