Mosman Apartment - Balcony Waterproofing and Leak Remediation
Mosman Apartment – Balcony Waterproofing and Leak Remediation
Mosman, NSW
Project Description
One of the greatest challenges in this project was managing access and accurately identifying all contributing factors to the persistent water ingress affecting both the commercial property and residential units.
As with many leak issues, there are often multiple sources at play. While it’s common to assume that the waterproofing membrane is solely to blame, our investigation revealed that this was only part of the problem. Through a detailed analysis of the building, we uncovered several additional failure points, including inadequate drainage, compromised external walls and flashings, poorly designed ledges, and cosmetic architectural elements that allowed water ingress.
By addressing each of these contributing issues, the project was successfully completed, and all leaks were resolved. The building committee played an active role throughout the project and were kept informed with regular weekly updates on progress.
