GPR has enormous potential for use on engineered structures. Over the past ten years many structural investigations have been conducted by STATS Geophysical which has resulted in a large knowledge base of reflection types obtained from various structural features.

In conjunction with our Structures and Materials divisions we have conducted numerous investigations aimed at determining construction detail and internal metalwork in a variety of modern and historic buildings.

Using Ground Penetrating Radar (GPR) allows rapid non-destructive coverage, with a depth penetration of up to 2m. The approach allows us to image multiple layers of construction detail, the calculation of thicknesses, and the location of internal metalwork including multiple layers of reinforcement.

We are able to cover large areas with non-intrusive, mobile data. Here in this example GPR is being used to map the location and depth of rebar in the floor slab (red=shallowest).
