Ground Penetrating Radar Serving Throughout the Greater Philadelphia Area

Ground Penetrating Radar Services in Philadelphia

Ground penetrating radar is the use of radio frequencies and electromagnetic waves to accurately detect underground utilities. At TLC we use a two-fold system to ensure the location of all underground utilities by using a state of the art GPR detector as well as electromagnetic locating wands.

This technology works by emitting high-frequency electromagnetic waves into the ground and bouncing wave frequencies back to the receiver that measures the strength of the reflection and the time it takes for the reflection to reach the receiver.

With this information, we can accurately measure the depth of a utility and identify the type of material of the utility.

More Info:

Unlike cable and pipe locators which rely on tracing a frequency applied to a metallic utility, GPR equipment is able to identify non-conductive targets such as PVC and HDPE as well.

At TLC, we have the capability to perform both traditional locating methods and modern methods that ensure utilities of all kinds can be located properly.

We are able to mark a utility’s horizontal location on the ground surface by making additional passes over the utility using our electromagnetic wand.

Frequently Asked Questions

How deep can the radar detect?

A: Depending on the type of surface the radar is used on, the waves can reach up to 100ft and as little as 3ft down. This has to do with the conductivity of the ground. For example, a lighter soil would be much more conductive than dense soil like clay.

Can GPR detect anything other than utilities?

A: Yes, the main purpose of GPR is to locate underground facilities, but the technology also works to find unmarked graves, underground voids, sinkholes, septic tanks, manholes, abandoned lines, weapons, drugs, cadavers, and cash. The technology will pick up any disturbances in the ground that indicate the presence of something.

What does the equipment look like?

A: The GPR detector could be easily mistaken for a small push mower. The device is mounted onto a cart that is pushed along the ground to pick up the signals and a screen is attached to the handle that displays information for the locator.

Our Electromagnetic wands are a bigger version of the handheld metal detectors you might see while entering a Phillies game. The wands are waved back and forth over the ground surface to pick up signals reflected off the underground facilities.
