Condition survey and remediation of bridge defects including cracking, spalling, honeycombing and reinforcement corrosion.
Defect remediation starts with a condition survey to establish the cause rather than the symptom, then repairs using mortar, crack injection or cathodic protection appropriate to the diagnosed mechanism. Treating the cause prevents the defect reappearing within a few seasons.
Concrete defects are rarely material failures in themselves; they are usually consequences of chloride ingress, carbonation, inadequate cover or water tracking through failed joints. Remediation therefore combines repair of the damaged section with removal of the transport path that delivered the aggressive agent.
