Selected case studies in Engineering Geophysics

Abstract

All geophysical methods have a specific niche application(s); however, some methods are more versatile than others and are applicable to a wider range of earth science problems. This is particularly true in the case of the GPR method, which is known to provide technical solutions in a diverse range of fields that include mining, hydrogeophysics, and engineering. This paper provides selected case study examples that illustrate the versatility and value of GPR within the field of engineering. Examples of specific applications of GPR in the engineering field include: Mapping reinforcing steel structures in concrete, Locating old foundations and building structures, Locating/tracking utilities, Mapping tree roots that threaten infrastructure, Characterising sinkholes, voids and subsidence, and Studying the integrity of concrete structures.
