Expert Waterproofing Sydney

Australian building codes require waterproofing in wet areas including shower recesses, bathroom floors around baths and showers, laundry floors, and balconies. Additionally, basements, retaining walls, and other areas exposed to moisture may benefit from waterproofing protection. We can assess your property and advise on specific requirements.

We use various waterproofing systems depending on the application, including liquid membrane systems for internal wet areas, torch-on membranes for external applications, sheet membranes for certain situations, and tanking systems for basements. We select the most appropriate system based on your specific requirements, substrate conditions, and environmental factors.

Curing times vary depending on the waterproofing system used. Liquid membranes typically require 24-48 hours before they can be tiled over, while torch-on membranes may be ready sooner. Weather conditions, temperature, and humidity can affect curing times. We always ensure proper curing before allowing subsequent work to proceed.

Yes, we provide formal waterproofing certification for all work that requires it under Australian building codes. This documentation is essential for building compliance, council approvals, and insurance purposes. Our certified waterproofers are qualified to issue these certificates upon successful completion of the work.

Waterproofing costs vary depending on the area size, system type, substrate condition, and complexity of the application. Internal wet area waterproofing typically ranges from $35-$80 per square metre, while external waterproofing may vary more widely based on specific requirements. We provide detailed quotes based on your particular situation. Our bathroom tiling cost guide includes waterproofing pricing details.

In some situations, it's possible to apply waterproofing over existing tiles using specialised systems. However, this depends on the condition of the existing tiles, the substrate underneath, and the specific application. For critical wet areas, we often recommend removing existing finishes to ensure proper waterproofing adhesion and compliance with current standards.

We provide a 7-10 year warranty on our waterproofing work, depending on the system used and application area. Our warranties cover both materials and workmanship, giving you confidence in your waterproofing investment. Warranty terms are clearly outlined in our quotes.

Properly installed waterproofing requires minimal maintenance. Regular inspection of surface finishes, prompt repair of any cracks or damage to tiles or finishes, and ensuring drainage systems remain clear will help maintain your waterproofing's effectiveness. We provide specific maintenance guidelines for your particular waterproofing system.
