Verify through-cracks without core drilling
Same crack on the surface. Very different renovation.
Seal, coat, monitor. A routine maintenance item, handled within the regular inspection cycle. Cost stays inside the operating budget.
Full-depth repair. Water, chlorides and CO₂ are already reaching the reinforcement. Requires injection, partial demolition or replacement, placing the project in a completely different cost class.

01. The Decision: Why this is the single costliest judgment call in an inspection report. 02. The Method: How crack polylines from both faces are geometrically correlated in the SWEA viewer. 03. The Outcomes: Overlap, near-miss, or no correlation, and what they mean for the damage scope. 04. The Value: Accurate, reliable data for better procurement and lifecycle planning.

Treating a through-crack as cosmetic defers a failure. Treating a surface crack as structural pays for a repair you didn't need.
The white paper shows how engineers make the right call from drone data alone, without drilling a single core.
