Non-Destructive Testing, or NDT, is a method used to assess the condition and strength of structures without causing damage. It is especially useful for existing buildings, renovations, and safety assessments.

NDT techniques help identify internal defects, voids, cracks, and variations in material quality. These tests allow engineers to evaluate structural performance without interrupting operations or damaging finishes.

Non-destructive testing supports informed decision-making for repairs, retrofitting, and maintenance planning. It is widely used for quality audits, building assessments, and life-cycle evaluations.

By using NDT, property owners and engineers can ensure safety while preserving structural integrity, making it a valuable tool in modern construction management.
