Slab scanning is a non-destructive testing method used to identify the location and depth of rebar, post-tension cables, and other embedded objects within a concrete slab or wall. It is an essential service for any structure repair or renovation work, as it allows contractors to accurately locate and avoid damaging these critical elements during the repair process. Slab scanning is typically performed using specialized equipment that emits electromagnetic waves or ground-penetrating radar to detect the presence of embedded objects. The data collected is then analyzed to create a detailed map of the reinforcement layout, including the spacing, depth, and size of the rebar or cables. This information is vital for ensuring the integrity of the structure during repair work and avoiding any potential safety hazards. By accurately identifying the location of these elements, contractors can safely drill, saw, or excavate without compromising the structural integrity of the slab or wall.
