Ground Penetrating Radar Systems (GPRS) was recently hired by a general contractor to conduct a GPR survey in Waterford, Michigan. Our scope of work was to survey a section of the floor to locate conduits prior to saw cutting. GPRS uses non-destructive testing equipment to locate post-tension cables, rebar, conduits, or other obstructions in concrete. Using GPRS is a safe, cost effective way to make sure you can safety drill or cut through a concrete slab.
