Subsurface Detection that Prevents Time Loss and Saves Lives

QRI's Geophysical Division was founded in 2004. Our crews can mobilize within 24 hours and as little as 8 hours – this prompt mobilization prevents costly construction delays. Pre-excavation identification of utilities prevents losses and saves lives. QRI has successfully mapped utilities, rebar & post tension cables, intraslab & sub slab voids, USTs, buried drum debris fields, and contaminants using a combination of technologies supporting GPS. QRI goes beyond One Call locates on public easements and performs private utility locating.

QRI has developed a non-intrusive geological mapping technology called Pulser™. Pulser™ defines underlying geology to a depth of 350 feet without extensive drilling. Using subsurface data visualization software, Pulser™ data is transformed into 2D and 3D representations of stratigraphy and lithology.
