Present technology cannot detect every pipe buried in the ground. A pipe must emit a signal, ether a naturally occurring signal or a signal transmitted by us, to be detected. The most common type of utility not detected are nonmetal service laterals and utilities under reinforced concrete slabs. At any site, there will probably be a few buried utilities that will not be detected. Our personnel are always available to explain the methods and their limitations as they pertain to your site.

Clients can help a utility investigation by providing mechanical drawings of what was buried at the site. Although the drawings may not be accurate, they help us know what to look for. These drawings often provide information on where pipes daylight and locations where we can connect transmitters or insert sondes. Clients should try to provide mechanical drawings when possible. The information these drawings provide is worth the effort of obtaining them.
