GPR is now widely used for assessing the interior of concrete structures. When cutting and coring for renovation and repair, avoiding reinforcing, post-tension cables and embedded conduits is a priority. GPR can sense both metallic and non-metallic features making it a versatile imaging tool. Construction records for many buildings are not readily available and construction often differs from design resulting in GPR being the only way to assure what is there.

Post-tension (PT) cables are used in concrete construction to allow thinner slabs and greater span lengths between support columns. These cables, composed of steel wires inserted into a plastic sheath, are subsequently “tensioned” and grouted after the concrete is poured.
