Radius Trench Drains

True radius precast trench drain features and benefits

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 true radius 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 trench drain widths of 2", 4", 6", 8", 10", 12", 18", and 24". The lengths of the trench drain sections will vary with the radius, but they are typically 8' sections. Radius trench drains are typically sloped at 0.5%, but any slope can be fabricated upon request.

Dura-Trench radius trench drains have many of the same standard features of our other precast trench drains. There are many different styles of frames offered including black powder coated steel, galvanized steel, stainless steel, and aluminum. The trench drain 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 trench drains to match any type of grating system.  The trench drain body shown here was created to work with a local foundry grate that was cast to the proper radius.  This trench drain was also specified with a flat bottom rather than with radius corners.  This trench drain had a 21'-4" center line radius and was constructed using 16 trench drain sections that were roughly 8'-6" in length.




Dura-Trench true radius trench drains can be utilized anywhere to make a unique statement.


A true radius trench drain like this one in a park setting does not have a segmented look like mitered straight trench drain sections would have.  Rather this trench drain fabricated by Dura-Trench seamlessly curves along the radius for a smooth flowing look and easy installation.

Use a prefabricated radius trench drain to follow a wall profile or any other radius.




No matter what the radius, the Dura-Trench line of trench drain products can seamlessly integrate with the architecture and design.  It is possible to make the trench drain an element of the design rather than a necessary eyesore.
