Do All Balcony Leaks Require Membrane Replacement?

Not always. Investigation is required to determine the cause of failure and whether the membrane remains serviceable.

Can Balcony Waterproofing Be Repaired Without Removing Tiles?

In some situations, yes. However, complete membrane replacement is often the most reliable long-term solution.

How Long Does Balcony Rectification Take?

Project duration depends on size, access requirements and the extent of remediation required.

Balcony Rectification in Coogee

Eastern Suburbs coastal strata postcode with a dense 1990-2015 mid-rise apartment wave.

Balcony Rectification across Coogee buildings

Salt-driven concrete spalling across the cliff-facing apartments, balcony rectification programs on the 1990s strata towers as original membranes reach end of life, and waterproofing rectification on the podium decks. Resident-impact planning is critical, the buildings run full year-round.

The Supcon approach is the same anywhere in Sydney metro: find the source, scope it properly, fix it once. The suburb’s build wave and exposure profile change the diagnosis, not the standard.

Why Balconies Fail

Balconies are complex building elements comprising multiple interconnected systems. These systems include waterproofing membranes, drainage systems, tile finishes, screeds, balustrades, structural concrete and junction details.

Failure in any one of these areas can allow water ingress and contribute to wider building defects.
