The value of the Ground Penetrating Radar (GPR) technique in the investigation of historic buildings is gaining increasing recognition. Initially developed for geological and ground engineering investigations, GPR surveys have proven to be very useful in the rapid - and non-destructive - location of metal structures such as cramps, dowels, beams and bolts within the structure of historic buildings. Particular success is also recorded in the measurement of material thickness in facing stones. This article seeks to offer recommendations for the design of surveys, the post-acquisition treatment of the data, and the appropriateness of specific target types for GPR surveying.
