3D LiDAR Scanning + Cathodic Protection: Find the 'Symptom' Before Failure, Stop the 'Cause' at the Rebar
Why modern structural inspection pairs two things: 3D LiDAR scanning that measures settlement, cracking and spalling down to millimeter level, then Cathodic Protection that stops the rebar corrosion that is the real cause. The scan → diagnose → protect → monitor lifecycle for bridges, buildings and railways — with the realistic accuracy (cm/mm) achievable, no overclaiming.
