Crosshole sonic logging CSL is a method to verify the structural integrity of drilled shafts and other concrete piles.. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of concrete soundness outside the cage.
