Lightspeed Locating, LLC specializes in two different methods of underground utility locating. The first method involves the use of an electomagnetic transmitter and receiver system. This is the most economical system used to produce accurate results for any conductive utility buried underground. This system also has a limitation that it cannot identify non-conductive utilities, such as plastic, cement, rubber, or utilites that have been repaired with any of the before mention materials. For these utilities, a GPR system would be utilized.
A GPR ( ground penetrating radar ) is similar to that of the electromagnetic system, but is a completely contained where both transmitter and receiver are contained as a single unit. A computer analyzer is also attached for the techician to record and view the scans across the ground as the radar is moved across the area being located. Radar waves are transmitted into the ground, bounce off any object withing a determined scope and then bounce up to the receiver and a three dimensional graph is recorded.
Further processing in our labratory can be done at a later time to enhance and edit all of the data to produce a full color 3-d image of the scanned area. This is particularly helpful when identifing multiple utilities crossing each other, anomolies that are buried underground, and non conductive utilites, such as water and sewer lines.
