GPR Inspection Benefits
This is a safe and non-invasive process: no evacuation of tenants or workers is necessary. Microwave radiation emitted is less than that produced by a cell phone. The Sensors & Software Conquest system can improve the safety of your project by identifying post tension cables, reinforcement, and live electric lines buried in slabs and walls. With it we can scan and mark a 2-foot by 2-foot area in less than an hour or verify the density of reinforcement in columns, slabs, and walls.

GPR Inspection Limitations
There are a few precautionary and/or 'road' rules to keep in mind (we like to be realistic): Green concrete impedes radar penetration. The scanned area must be at least 3 inches away from obstructions. Multiple layers of rebar are difficult to detect if they are closely aligned with the layer above. Tile, grout, insulation, and roofing materials layered above the concrete strongly attenuate the radar signal. The size (or diameter) of reinforcement cannot be determined from the GPR scan. The bottom of the slab is, at times, difficult to see.
