Ground Penetrating Radar (G.P.R)
CAL G.P.R specializes in the latest Ground Penetrating Radar (G.P.R) technology. G.P.R can be utilized to image both concrete slabs and walls, and can accurately locate metallic and non-metallic reinforcement and pipes in and below concrete slabs.
Our highly trained technicians can help you locate and map the positions of rebar, Post-Tensioned cables, conduit, voids, reinforcing steel, and other near-surface anomalies. We give you a safe place to drill – keeping your project safe, on budget and on schedule.
In addition, G.P.R can detect flaws in concrete structures. We have experience in detecting the absence of grout in concrete block walls, and missing rebar. We can verify slab thickness and determine the depth of material cover on reinforcement. G.P.R emits very low energy high frequency radar waves (unlike the gamma rays used in X-Ray radiography). This allows G.P.R to be used in buildings while residents are still present. Unlike concrete X-Ray (radiography) G.P.R presents no risk to residents or technicians working in the test area because there is no radiation hazard. G.P.R is very fast, it allows for real time imaging results, unlike X-Ray. G.P.R works when there is only access to 1 side of a structure, requires only 1 technician, and is capable of performing in slab on grade situations. The equipment produces quick results and is capable of rendering a typical single scan of a 2’x2’ area in about 10 minutes.
