Assesment of material layers in building walls using GeoRadar

Assessment of existing buildings' recycling costs often requires a destructive method to look through its building elements like walls and floors. In order to answer what materials comprise a wall, one often has to obtain an explicit overview of the cross-section - either by drilling or carving out a piece. Ground-penetrating radar (GPR) presents the way to examine the walls without a destructive invasive process. GeoRadar has been successfully utilized in other fields, such as archaeology Zhao et al. [2013], seismology Zheng et al. [2019] and civil engineering for non-destructive examination Morris et al. [2019]. In order to identify materials in layered structures, one could refer to the research for a similar problem.
