Underground Utility Locating and Marking with GPR

Locating underground utilities is an important necessity before land excavation on a construction site. If you start digging without professional utility locates in Colorado, you will most likely hit a delicate utility line and cause danger.  Good utility locating services can help you find the location of various underground utilities for proper marking and documentation.

One of the specialized utility locating equipment is a ground penetrating radar or GPR. In this blog, you will discover a few more things about GPR technology and its usefulness in underground utility locating.

How Does GPR Work in Utility Locating?

Determining the target location of underground utilities and measuring the characteristics of the area can be a very complicated process. A good underground gas pipe locator helps assist in this process by providing the right tools to test the area. GPR utility detection works through the following steps:

  • The antennas transmit and receive frequencies
  • Radio waves are emitted to penetrate the ground, and the antenna detects the  signal that reflects 
  • The signal provides detailed information showing the size, depth, and location of objects.

Hiring a professional utility locates in Colorado helps to interpret the visual data to pinpoint the exact location of the target utility. It also means that you can easily determine the safest place to dig and proceed with your project.

Types of GPR Tools You Should Know

GPR equipment may work based on the same principle, but they have different features and applications. You need to choose a GPR device that suits the needs of your project. The following are some of the major types of GPR devices:

  • All-in-one system: This is a straightforward and user-friendly device that focuses on doing a common function, locating utilities.
  • Modular system: Modular GPR products are common because of their versatility and can be used for utility location, geophysical measurement, and quality scanning.
  • Concrete scanner: Just like the name, this device is designed to scan concrete land and detect target utility lines that may be underground. 


Of course, there are various options when it comes to choosing an underground gas pipe locator. The GPR device you choose will depend on the kind of land you want to measure and the kind of data you need to collect. Any of the devices above will help you locate utility lines and maintain safety while digging to avoid potential danger.
