St. Louis Testing Laboratories now has the capability to inspect concrete structures, such as floors, decks, slabs, walls and parking garages with the objective of locating rebar, tension cables, voids, conduit and PVC pipes.  Additionally, slab thickness determinations can be made.

These inspections are conducted using ground penetrating radar (GPR) technology, including state of the art scanning instrumentation and interpretative software.

Targets can be located to depths of up to 18 inches in concrete.

Safer and more efficient than radiography (x-ray) and requires only single-sided access.  Can be used in conjunction with radiographic inspection to estimate the relative size of embedded features.
