Warning tape cannot be detected with any manchine while it is underground, but is made of strong durable polyethylene to alert crews when digging and prevent dig-ins by giving resistance and show bright colors to alert crew what type of buried lines, cables or pipes may lie below.
SignsLabelsTapesandMore.com has made sure that our underground warning tape is made to meet the most extreme conditions and will last for many years while being underground and not lose the vibrant colors that are set by the APWA.
How to use Warning Tape:
Match the underground tape to your application. Make sure the length is long enough.
You should bury the tape 4”- 6” below the surface (NOTE- The deeper you bury the warning tape the wider it should be).
To ensure that a contractor will have enough warning before digging up utilities, you should place a shovel on top of material and measure up to where the metal meets the wood handle then add 2 inches. If you want to calculate a backhoe digging then measure the bucket half way up and add 2 inches. Both scenarios will give digger/ operator enough distance to see the underground warning tape before actually hitting the buried utility lines.
If you do not have that type of depth to work with then keep warning tape above utilities as much as possible while keeping the warning tape underground at least 4 inches.
