Why Balcony Leaks and Repairs Often Fail
Balcony defects often develop when waterproofing membranes fail or when water penetrates through joints and building interfaces.
Balcony doors and thresholds are one of the most common sources of water ingress, particularly where detailing does not allow for waterproofing terminations or drainage.
Many balcony repairs fail because the source of water ingress has not been properly identified or the repair system is not suitable.
Long-lasting balcony remediation requires correct preparation, engineered waterproofing systems and experienced installation.
That’s where a balcony remediation specialist makes the difference.
Proper balcony remediation usually involves:
- Identifying the source of water ingress
- Removing failed waterproofing systems
- Preparing substrates correctly
- Installing engineered waterproofing systems
- Detailing balcony junctions correctly
