Geoforensic investigation of cavity and settlement for abutment bridge using electrical resistivity imaging was conducted at Federal Highway FT02 Sect. 12.00 Klang. The objective of the investigation is to identify the cause of undulation occurred beneath the abutment bridge and cause discomfort to the road users and in the same time proposed rehabilitation method to solve the problems. Electrical resistivity imaging and JKR probe were used to identify the subsoil profile properties and the occurrence of water seepage. Findings reveal that by using the electrical resistivity imaging, the water seepage were clearly tabulated beneath the subsoil of the investigated areas and in clearly indicated that the soil is in weak conditions. This fact was also supported by the data of JKR probe recorded at the same location of the electrical resistivity imaging. Thus, the rehabilitation of the problems was proposed to overcome the settlement of the site. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
