Utility Trenches

Dura Trench Utility and Cable Trenches are the first utility trench on the market to offer fully integrated channel strut cast into the body of the trench.  These utility trenches can be used for electrical, hydraulic, water, sewer, gas, low voltage, high voltage, chemical piping, or any other process that requires a cable trench or utility trench.  The integral channel strut is anchored into the concrete so that any pipe diameter that you can fit into the utility trench body can be supported without concern.  The utility trenches can be pre-sloped to allow for drainage and/or can have covers with gaskets to reduce water intrusion.  The chemical resistance of the polymer utility trench body makes this a viable secondary containment vessel.  For strong chemical containment the bodies can be made with our chemical resistant vinyl ester resins.  There is a wide selection of available frames for any application.  With standard utility trench widths up to 48" wide the Dura Trench system can handle most any design consideration.  Also note that Dura Trench can make sweeping turns, divided trenches, and other custom requirements.

This secondary containment utility trench comes with built in 1 5/8" channel strut (at 48" O.C. typ.).  There is no internal bracing that will limit the ability to install piping.  All system frames come with installation devices standard.  View the 12" wide trench covers that fit on this size utility trench.  This size utility trench is typically used for data cables, electrical wiring, and small diameter pipes.

Dura Trench manufactures an innovative line of precast utility trenches.  Our utility trenches were designed to be fast and easy for the installer.  They come fully assembled, numbered and ready to install.  These utility trenches can be used for high voltage electrical, low voltage electrical, compressed air, chemical feed lines, water piping, hydraulic lines, drain lines, or virtually any other application.

The utility trench body can be ordered in virtually any width.  We typically build our utility trenches with a channel strut cast into the sidewall and/or bottom of the trench body.  The precast utility trench body is constructed from a fiber reinforced polymer concrete.  This makes it extremely strong and durable yet light weight.  Most precast utility trenches do not have the option for channel strut to be factory installed and if it is, they usually attach it on the inside which takes away from the width of the utility trench.  

Unlike most precast utility trenches, the Dura Trench utility trenches can be pre-sloped.  This allows the utility trench to drain to an outlet pipe if needed.  Our precast utility trenches can also slope to a sump location where an electric sensor or visual monitoring point can be installed to determine if piping is leaking inside the utility trench.  This can be extremely beneficial for environmental compliance and system monitoring without having to remove sealed or heavy utility trench covers.

 

The most common utility trench widths are: 8" utility trench, 10" utility trench12" utility trench18" utility trench, 24" utility trench, 30" utility trench, 36" utility trench, and 48" utility trench.  Other sizes can be manufactured upon request.

The precast utility trench body is also chemical resistant acting as a secondary containment system for piping applications.  The utility trench body is offered in two primary resin varieties: Polyester and Vinyl Ester.  The polyester utility trench is typically sufficient because of the limited exposure time of a secondary containment application.  The vinyl ester utility trench body is only selected when chemicals are particularly reactive or longer exposure times are expected.  Note that the standard channel strut that is installed is the galvanized strut, but we can provide FRP or stainless steel channel strut in our utility trenches upon request.

The Dura Trench precast utility trench product line can have many different types of tops or covers.  Our most common utility trench cover is a simple checkered plate reinforced for the traffic loading.  We can offer covers in epoxy coated steel, galvanized steel, stainless steel, FRP, and aluminum.  In some cases, we have also supplied grating where the client wants to see the piping.  Dura Trench also offers covers with a gasket system for their precast utility trenches.  The gasket helps keep storm water or wash down water out of the utility trench.

We have constructed many utility trenches with custom features.  Some of the custom features that keep coming up are sweep turns and dividers.  A sweep turn is needed when a large diameter pipe is being used inside the utility trench.  A divider is typically used for separating either high and low voltage electrical or for separating plumbing from electrical in a utility trench.

Dura Trench precast utility trenches have been used for projects like power plants, water treatment plants, wastewater plants, steel mills, automotive manufacturing, research facilities, laboratories, aircraft hangars, mining, substations, and manufacturing facilities.  When your application calls for a precast utility trench choose a Dura Trench!
