Structural crack A structural crack is a crack that may affect the strength, stability, or load-carrying capacity of concrete rather than only its appearance. It typically requires professional evaluation.
Structural cracks can result from foundation movement, excessive loading, reinforcement issues, or significant settlement. Their width, depth, pattern, and location help determine whether the damage is cosmetic or affects the integrity of the pavement. Unlike minor surface cracks, structural cracks often require more extensive repairs or replacement.
