Detection Services employs the use of state of the art, handheld Concrete Penetrating Radars which are able to detect minute fractures, voids or any imperfections within a concrete slab. We can accurately measure slab thickness as well as locate and map the reinforcing steel structures within a concrete slab, beam or column.
Although Concrete Penetrating Radar is a relatively new field, our experienced technicians have gained a lot of knowledge by being part of some of the biggest construction projects in the country, such as the Newmarket Motorway Viaduct Replacement project, maintenance works on the Auckland Harbour Bridge and a myriad of jobs within the earthquake affected Christchurch area.
The information we provide structural engineers, designers or even anyone just wanting to drill or cut through concrete is essential in the analysis, maintenance and design of better and sturdier concrete structures in New Zealand.
Do you only need your reinforcing bars located before you drill? That’s fine too, no job is too small or too big for our Concrete Penetrating Radars. GPR technology is completely non-destructive and will give very high resolution information on location and depth of any steel structures/bars, precise concrete thickness, voids, cracks, and it can penetrate through as much as 500mm of concrete/asphalt etc.
