Ground Penetrating Radar - GPR by modern equipment has grown in importance in recent years in non-destructive testing. Estimating steel rebar position and diameter is the main focus for assessment of existing reinforcement concrete facilities. This paper presents the latest modern non-destructive technique – suitable for testing reinforcement concrete members. The capabilities of this technique for locating reinforcement bars in unilaterally accessible, densely reinforcement slab are described.
