GPRS Locates Live Conduits Prior to Saw Cutting at the Cathedral Parking Garage
Ground Penetrating Radar Systems (GPRS) was requested on site by a general contractor to perform a Ground Penetrating Radar (GPR) survey at the Cathedral Parking Garage in Cleveland, Ohio. The contractor needed to remove about 20’x20’ section of concrete on the ground floor. The contractor needed to know if there were any conduits in the area to avoid saw cutting through them. GPRS located three live electrical conduits and one communications conduit that were just below the concrete slab that would have been saw cut. The conduits were painted on the surface with depth indications so that the contractor could safely saw cut over or around them without hitting the conduits. Without GPRS on site there could have been serious damage to the electrical and communications lines. Before you saw cut or core drill, call GPRS to know what’s underground!
Ground Penetrating Radar Systems is the best way to ensure the locations of reinforcement and conduits prior to saw cutting/ drilling through concrete.

We also have the capabilities of locating underground utilities, UST’s, and voids.
Ground Penetrating Radar (GPR) Equipment
GSSI SIR – 3000
GPRS uses a Geophysical Survey Systems Inc. (GSSI) SIR-3000 Radar unit. This is the most advanced GPR available. It allows for onsite interpretation, as well as stores data for later processing. This equipment is self-calibrating, allowing more precise depth and location measurements.
1600 MHz Antenna
This antenna allows data collection to a maximum depth of approximately 18”, depending on concrete conditions
