GPR has enormous potential for use on engineered structures. Over the past decade many structural investigations have been conducted by RSK Geophysics which has resulted in a large knowledge base of reflection types obtained from various structural features.
In conjunction with our Structures and Materials teams we have conducted numerous investigations aimed at determining construction detail and internal metalwork in a variety of modern and historic buildings, including tunnels (both concrete and masonry construction).
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 voids, and internal metalwork including multiple layers of reinforcement.
