Radius Trenches

 


Radius trench drains have been specified for years, but until now have been extremely difficult to construct. Eric'sons Dura-Trench now offers a prefabricated drainage trench for those special applications where a seamless curve is required. Radius trench drains are custom built to your specifications. Eric'sons will build them to any radius in most common widths. We currently offer internal widths of 4", 8", 10", 12", 18", and 24". The lengths of the drains will vary with the radius, but they are typically 8' sections. Radius drains are typically sloped at 1%, but 0.5% slope or non-sloping units are available.






Dura-Trench radius drains have many of the same standard features of our other fiberglass drains. There are many different styles of frames offered including black powder coated steel, galvanized steel, stainless steel, and aluminum. The grates are offered in all load classes in materials such as galvanized steel, aluminum, stainless steel, cast iron, bronze, etc.






Dura-Trench can offer radius trenches to match with any type of grating system.  The trench body shown here was created to work with a local foundry grate that was cast to the proper radius.  This trench was also specified with a flat bottom rather than the standard radius corners.  This trench had a 21'-4" center line radius and was constructed using 16 pieces that were roughly 8'-6" in length.






A true radius trench like this one in a park setting does not have choppy mitered straight sections, but seamlessly curved radius components that fit together neatly.  





This smooth radius trench matches the curvature of the wall behind it making the design seamless.
