Signs of Waterproofing Failure
Recognising the signs of waterproofing failure early can prevent extensive damage to your property. If you notice any of the following symptoms, it may be time to have your waterproofing checked and repaired:
Areas That Commonly Require Waterproofing in Strata Properties
Certain areas of strata properties are more susceptible to water damage. Regular waterproofing of these areas is essential to avoid costly repairs. Key areas that commonly require waterproofing systems include:
- Balconies and Rooftop Areas: These areas are frequently exposed to the elements and are highly vulnerable to water ingress.
- Bathrooms and Wet Areas: Without proper waterproofing, moisture can seep through walls and floors, leading to significant structural damage.
- Planter Boxes and Retaining Walls: Water accumulation in these areas can cause long-term damage to your strata property. Regular maintenance ensures moisture doesn’t affect the structure.
How ATCO Projects Solves Your Waterproofing Problems
At ATCO Projects, we offer a systematic approach to strata waterproofing in Sydney, ensuring that every area of your building is fully protected. Our process includes:
Inspection and Diagnosis
We begin with a thorough inspection of your strata property to identify potential waterproofing issues. Our team assesses areas prone to leaks and moisture damage, including balconies, bathrooms, and retaining walls. We provide waterproofing maintenance advice and identify any underlying problems, such as concrete spalling or concrete cancer, that could be affecting the structural integrity of your building.
Surface Preparation and Removal
Once we’ve identified the problem areas, we prepare the surfaces by removing any old or damaged materials, such as cracked grout or tiles, to ensure a strong bond with the new waterproofing membrane.
Membrane Installation
We apply high-quality waterproofing membranes to protect your strata property from water damage. These membranes create a durable barrier, preventing water ingress in critical areas. Whether it’s for balconies, bathrooms, or retaining walls, our expert team ensures the membranes are installed securely to provide long-lasting protection.
Finishing and Certification
After the waterproofing membranes are in place, we restore the area with finishes like grout, tiles, or seals. We conduct a final inspection to ensure everything is in perfect condition. Upon completion, we provide certification to confirm that the work complies with local building codes and regulations.

Frequently Asked Questions
1. How long does waterproofing last?
When installed correctly, waterproofing membranes can last up to 10-15 years. However, regular waterproofing maintenance is recommended to ensure long-term protection and identify any potential issues early.
2. How do I know if my strata building needs waterproofing?
If you notice signs like visible leaks, damp spots on walls or ceilings, or mould growth in wet areas, your strata property may need waterproofing. These issues often indicate moisture ingress that needs to be addressed before further damage occurs.
3. Is waterproofing required by law?
Yes, strata managers and owners corporations are required by law to comply with local building codes, including waterproofing standards, to prevent water ingress and protect the structural integrity of the building.
4. What are the common areas that require waterproofing in strata buildings?
In strata properties, areas like balconies, bathrooms, rooftops, planter boxes, and retaining walls are most vulnerable to water damage. Regular waterproofing of these areas is essential to prevent moisture from seeping into the building.
5. How can I maintain my strata waterproofing system?
Regular inspections are key to maintaining your waterproofing systems. Look out for signs of wear, such as cracks, leaks, or damage to seals. Scheduling annual maintenance checks helps extend the life of your waterproofing and avoid costly repairs.
6. Is waterproofing mandatory for strata buildings in NSW?
Yes. Waterproofing is required under the National Construction Code (NCC) and relevant Australian Standards. Any balcony, rooftop, podium slab or wet area exposed to moisture must be protected with a compliant waterproofing membrane system.
Failure to maintain compliant waterproofing can expose an owners corporation to:
- Structural deterioration
- Insurance complications
- Legal liability
- Breach of statutory maintenance obligations
For strata committees, proactive waterproofing reduces governance risk.
7. What Australian Standards apply to waterproofing membranes?
Commonly referenced standards include:
- AS 4654.1 & AS 4654.2 – Waterproofing membranes for external above-ground use
- AS 3740 – Waterproofing of domestic wet areas
- NCC performance requirements for moisture management
A compliant waterproofing membrane in strata buildings must meet these standards for durability, adhesion, and water resistance.
8. Does strata waterproofing require certification?
Yes. Upon completion, waterproofing works should be certified and documented. This typically includes:
- Scope of works
- Membrane product specifications
- Installation methodology
- Compliance confirmation
Documented certification supports strata records and insurer requirements.
9. Who is responsible for waterproofing in strata buildings?
Responsibility depends on whether the affected area is classified as common property or part of a lot. In many cases:
- Balcony slabs are common property
- Internal wet areas may fall under lot owner responsibility
- Structural membranes beneath tiles are typically common property
Strata managers should confirm responsibilities through the strata plan and legal advice where required.
10. What maintenance reduces future failures?
Ongoing care should include:
- Clearing drainage outlets
- Checking sealants and movement joints
- Monitoring cracks
- Removing debris build-up
Preventive maintenance extends membrane lifespan.
11. How often should strata buildings be inspected?
Annual inspections are recommended, particularly for:
- Exposed balconies
- Rooftop membranes
- Planter boxes
- Retaining walls
Routine reviews identify minor issues before major remediation is required.
