Case Study:
240 Wyndham Street, Alexandria
Multi-Defect Facade Rectification
Before
The Challenge
The Owners Corporation of 240 Wyndham Street, Alexandria — a multi-storey Class 2 residential building on the corner of Wyndham and Mandible Streets — engaged Wardell Remedial to rectify a complex series of facade defects across both street elevations. Following an independent investigation by structural engineers Lindsay & Associates, distinct defect types were identified including 92 discrete concrete spall locations, widespread cracked render, waterproofing failures, unprotected slab edges and vertical brickwork cracking.
Concrete Spalling — 92 locations
Cracked Render
Waterproofing Failure Unprotected Slab Edges
Vertical Brickwork Cracking
The scale and complexity required a registered builder capable of executing a regulated design across the full facade perimeter of an occupied residential building with full DBP Act compliance.
