The difference between Public Utility Locator & Private Utility Locator
- Public utility locator identifies utility lines on public property. Public utility lines are within a network of electricity, water, sewer, gas systems which are managed by providers. These lines often stop on the trail to your land at the meter. Public utility locating service is at no cost.
To avoid failure in digging, you need to contact public utility locator first by dialing 811
- Private utility locator identifies utility lines on private property. Private locator often comes in where public utility companies cannot perform the service. There is a fee to private utility locating service depending on the scope of the project, the objects to be identified.
Ground penetrating radar used by private utility locator to determine multiple layers and thickness of each layer
In Pascagoula, MS, we performed GPR scanning for an engineering company using our utility cart. The company needed to understand what utilities were under asphalt, concrete and sand layers in a 100 x 10 foot area about 8 to 10 feet deep. We were able to approximate the thickness of each asphalt, concrete, and sand layer because the moisture levels were controlled and the spacing of the rebar allowed us to gather sufficient information.
Locate utilities using GPR scanning for military base
A general contracting company asked Penhall Technologies to perform GPR scanning at a military base. We used a 400 MHz antenna and a utility scan cart to locate the utilities that were about 3 feet deep, in a 240 x 90 foot area.
