Westfield Underground Car Park Structural Crack Repair Programme
Slabs, walls, joints & crack injection remediation delivered at Westfield Shopping Centre, Sydney, NSW.
Project Overview
This Westfield Shopping Centre, Sydney, NSW project involved slabs, walls, joints & crack injection. Works were delivered under live car-park staging conditions, with the repair programme focused on safe access, reinforcement treatment and durable concrete reinstatement.
THE PROBLEM
Static slab and wall cracks, movement-related cracking, leaking construction joints and active water-bearing cracks affected multiple underground car-park levels.
THE REPAIR
Structural epoxy and polyurethane injection systems were used alongside routing and sealing, joint remediation and localised crack stitching where required.
THE OUTCOME
A large-scale structural and water-ingress crack repair programme was completed while unaffected parking areas remained operational.
SITE CONDITIONS
Live vehicle movements, underground access and active water ingress required staged work zones and progressive reopening.
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.
