Concrete & Pavement

GPR sees widespread use for investigating the structural state and physical properties of concrete structures, roads, runways and similar engineered environments. The questions addressed vary from layer thicknesses, to presence and location of reinforcing and tensioning members to the presence of voids, water content and compaction.

Concrete Structure Assessment

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.

Roads & Pavement

Road pavements and sub-base materials provide unique opportunities for using GPR.  GPR's ability to penetrate asphalt and concrete pavements and detect and delineate subsurface structure delivers invaluable information for asset management and maintenance planning. Being able to ascertain the construction practice, determine pavement thickness and locate variations in the base coarse leads to informed maintenance and repair expenditures.
