Major Concrete Cancer Lintel Replacement & Remediation
Concrete lintels, reinforcement & façade openings remediation delivered at Mosman, NSW.
Project Overview
This Mosman, NSW project involved concrete lintels, reinforcement & façade openings. Works were delivered under staged structural lintel works conditions, with the repair programme focused on safe access, reinforcement treatment and durable concrete reinstatement.
THE PROBLEM
Concrete cancer affected numerous reinforced-concrete lintels, causing reinforcement corrosion, cracking, rust staining, delamination and spalling above façade openings.
THE REPAIR
Unsound concrete was removed, reinforcement cleaned and treated or replaced where required, and severely deteriorated lintels reconstructed or replaced using engineered repair methods.
THE OUTCOME
Concrete-cancer-affected lintels were systematically remediated across nominated elevations and surrounding façade areas reinstated.
SITE CONDITIONS
Multi-storey façade access, temporary support, occupied strata conditions and staged structural lintel works required careful sequencing.
A Controlled Remedial Process
Each project follows the actual repair requirements, access constraints and site conditions.
Inspection & Defect Mapping
Affected areas were inspected, mapped and confirmed so the repair extent could be planned before breakout.
Controlled Concrete Breakout
Unsound and delaminated concrete was removed back to a sound substrate while surrounding areas were protected.
Reinforcement Treatment
Exposed reinforcement was cleaned, assessed and treated, with replacement or augmentation completed where required.
Structural Reinstatement
Compatible structural repair mortar was placed and finished to reinstate the original concrete profile.
Protective Interfaces
Repair edges, interfaces and exposed surfaces were detailed to suit the surrounding structure and site conditions.
Final Inspection
Completed repair areas were checked for finish, continuity and compliance before the work zone was handed back.
