Using Georadars for Evaluating the Thickness of a Concrete Layer

Abstract

Abstract At present, georadiolocating research is actively used in various fields of engineering surveys. In the article, we discuss the scan for concrete structures and assess their thickness and condition using this method. The principle of operation of radar is based on the emission of electromagnetic pulses of the radio range and the reception of a signal reflected from the interface of the media (the boundary between the layers of the studied soil stratum having sharply different electrophysical properties). The aim of the study is to accurately determine the location and layout of the reinforcing bar, tension cables, beams, pipelines, voids, and plates. The presence of metallic objects in the studied strata is a valuable identification feature, and metal objects known to be located are convenient marking elements of the section.
