New Concrete Radar at the SZEpalab Laboratory: Proceq GP8800

The SZEpalab laboratory has expanded its instrumentation portfolio with a state-of-the-art device designed for non-destructive structural diagnostics: the Proceq GP8800 concrete radar, which utilizes the advanced SFCW GPR(Stepped-Frequency Continuous-Wave Ground Penetrating Radar) technology for the internal investigation of reinforced concrete structures. The device was developed by Screening Eagle, specifically for applications where accurate and reliable information is required about embedded elements within structures.

3D Layered Model of Reinforced Concrete Structure

The GP8800 is a compact, wireless concrete radar equipped with an antenna operating in the 400–6000 MHz frequency range. It is capable of generating high-resolution 2D and 3D radargrams, allowing for detailed layer and object analysis within reinforced concrete structures, up to a depth of approximately 65 cm.

The Proceq GP8800 offers professional solutions for the following non-destructive testing applications:

  • Determination of concrete cover and structural thickness
  • Localization of embedded elements (e.g. rebar, post-tensioning cables, electrical conduits, piping)
  • Detection of delaminations, cracks, and voids
  • Identification of layer interfaces and material separations
  • Pre-checking drilling and cutting locations to reduce risk

The GP8800 concrete radar is suitable for use in construction diagnosticscondition assessment of existing structuresheritage investigations, and research-based documentation. It is particularly advantageous in situations where structural disassembly is not permitted or not feasible.

Real-Time GPR Scanning Visualization

All testing services are carried out by the qualified technical staff of the SZEpalab laboratory, including data interpretation and documentation of the results.
