Locating Utilities In Concrete

Ground Penetrating Radar is used to “see” through concrete to discover where the underground utilities are located. It works alongside Electromagnetic Induction (EI). It uses a hand-held device that consists of a wand that can locate metallic pipes, live electronic currents, or signals from live electrical currents.

The Art Of Locating Utilities In Concrete

Locating utilities in concrete and its importance of being able to use these devices to locate underground utilities means that concrete sidewalks, parking lots, and streets do not have to be torn up in order to find these utilities, saving thousands of dollars in costs. It is safer to use these devices and less costly.

The following examples illustrate the advantages that these systems allow:

Example 1:

A high voltage electric duct right in the path of excavation. Contractors who were working on the project were aware that the wire was there, but was surprised to learn that it was only four feet deep.

Example 2:

It was requested that all utilities be found and assigned a depth prior to a crane concrete scannjing markingsbeing put in the area. The weight of the crane alone would have crushed any utility within 30″ of the surface.

In these cases, the utilities were located easily and saved a lot of time and expense that would have had to be expended to dig and reroute these utilities. As it is, since it is known where these utilities are located, other arrangements can be made.

GPR can locate reinforced concrete pipe used in underground sewer systems and storm drainage systems. These units usually run under roads and parking lots, so it is imperative that they are located.

It is actually surprising how many utilities do run under roadways and parking lots, and now how much time and money is saved by using this new technology.
