Use of Ground Penetrating Radar in the Evaluation of Wood Structures: A Review

This paper is a review of published studies involving the use ground penetrating radar (GPR) on wood structures. It also contains background information to help reader understand how GPR functions. The structures began grow in popularity at turn millennium. has many characteristics that make it attractive as an inspection tool for wood: faster than acoustic and stress wave techniques; does not require couplant; while can detect presence moisture. Moisture detection prime concern, several researchers have labored measure internal moisture using GPR. While there been laboratory wood, its large limited. identified knowledge gaps need be addressed improve efficacy reliable structure. Chief among these gaps, ability distinguish type feature from output identify decay.
