Used for installations under concrete, asphalt, pavers, or in gravel roads. The most common installation is the loop tied directly to the rebar before concrete is poured. Wire is designed for a direct burial application.
Unlike loops wrapped through PVC, The BD Loops Direct Burial Loop does not have an air pocket resulting in fewer repeat service calls due to phantom detections caused by ground vibration.
Our Direct Burial loops are build with Solid 16AWG to create a tough rigid product that won’t fall below the rebar pattern. Installing a BD Loops Direct Burial loop over rebar is a snap! Simply offset the loop from the rebar pattern and tie it down with the supplied cable ties.
The loop wire has arrows indicating the direction of current and lead-in is red/black allowing easy understanding of phasing. To learn more about the effects of loop phasing click here.
Twisted jacketed lead-in prevents “coil back” from normal twisted lead-in, preventing wasted time untangling lead-in wires.
Each direct burial loop comes with an installation kit including easy to follow instructions, cable ties for installation on top of rebar, ground stakes for laying out the loop in gravel and dirt roads (remove ground stakes before burying loop), and stickers for easy identification after the loops have been installed.
Installing a loop under pavers?
If the sub-base is concrete or a slurry DO NOT use a Direct Burial loop. Saw-Cut in a BD Loops Saw-Cut Loop instead.
Sandwiching wire between two hard surfaces will cause the loop to eventually fail.
