Ground Penetrating Radar Systems was contacted by a customer to locate underground utilities in a future America Credit Union location. The customer was going to excavate to put a new building on the lot and were concerned about hitting surrounding utilities. GPRS came out and successfully located all of the live power lines as well as the utilities.

Ground Penetrating Radar Systems used a 400 MHz antenna for this application and a Radio Detection (RD) device to detect electrical current deep in the soil. GPRS’ 400 MHz antenna was ideal because of its accurate deep penetration and...

Ground Penetrating Radar Systems (GPRS) was contacted by a customer to locate the main electrical line feed at Vivint Arena, the home of the Utah Jazz. Although the customer had already used both a public utility locator service and a private utility locating service (one of our competitors) to have the area scanned, these services were unable to locate the electrical line in question. After GPRS scanned the site, we were able to locate the electrical conduit, and this information was then provided to the customer. The customer was very impressed with the thoroughness, creative problem...

The pictures you see below are from a local attraction in Orlando, FL. The demolition contractor was removing a curb when they unknowingly broke a main feed line for the sprinkler system. This would normally not have been something difficult to remedy. However, they did not know where the shut-off valve was for the system. With this problem hundreds of gallons of water were wasted and the ground will have to be repaired prior to work continuing.

This is not an uncommon issue on job sites today. To cut cost contractors are performing site work, demolition and excavation without...
