About Balcony Waterproofing
Balconies are exposed to weather while supporting tile finishes and connecting to internal spaces, making waterproofing critical. Failed balcony waterproofing is one of the most common causes of building defects, leading to water damage, concrete cancer, and interior leaks. Our balcony waterproofing systems comply with AS 4654.2 and provide long-lasting protection.

Where required, tiles and screed are removed to access the structural substrate for waterproofing.
Substrate Preparation
The structural slab is repaired, cleaned, and prepared with appropriate falls to drainage points.
Membrane Application
Waterproofing membrane is applied with proper detailing at edges, penetrations, and drainage connections.
Tiling & Finishing
Protective screed and tiles are installed over the waterproofing, completing the trafficable surface.
Frequently Asked Questions
Common questions about our balcony waterproofing services.
How do I know if my balcony waterproofing has failed?
Signs include water stains on ceilings below, cracked or loose tiles, efflorescence (white salt deposits), rust stains from concrete cancer, and puddles that don't drain properly after rain.
Can balcony waterproofing be repaired without removing tiles?
In some cases, minor repairs can be made without full tile removal. However, for reliable results with failed waterproofing, removing tiles and screed to access the membrane is usually recommended.
What causes balcony waterproofing to fail?
Common causes include inadequate original waterproofing, membrane damage during tiling, failed details at edges and drains, building movement, and age-related deterioration.
How long does balcony waterproofing last?
Quality balcony waterproofing should last 15-25 years with proper installation and detailing. We use premium membrane systems with manufacturer warranties for long-term peace of mind.
