#ndt Infrasense completed a ground penetrating radar (GPR) survey to map the reinforcing steel layout and depth along the underside of a bridge deck in Fond du Lac, Wisconsin. The rebar map will be used by the client to assess the load carrying capacity of the structure and ultimately to update the load rating. The GPR survey was carried out using a high-resolution handheld unit. Longitudinal and transverse data-lines were collected to provide a 3-dimensional dataset of the subsurface.
