The Ultimate Guide to Waterproofing Bathrooms, Balconies, and Basements
Protect Your Property in Melbourne with Expert Waterproofing Solutions
Introduction: Why Waterproofing Matters in Australian Homes
Waterproofing is one of the most essential—but often overlooked—elements in home construction and renovation. Whether you're building a new home in Melbourne or upgrading an existing property, ensuring your bathroom, balcony, or basement is properly waterproofed can prevent costly structural damage, mould growth, and health issues.
At TopOne Tiling Group, we specialise in professional waterproofing services across Melbourne and regional Victoria, helping homeowners and builders achieve long-lasting protection and compliance with Australian Standards (AS 3740).
What Is Waterproofing?
Waterproofing is the process of making surfaces and structures resistant to water infiltration. This is especially important in high-moisture areas like:
- Bathrooms and wet areas (showers, floors, walls)
- Balconies and terraces
- Basements and retaining walls
A properly waterproofed area prevents water from seeping into the structure, reducing the risk of leaks, rising damp, efflorescence, and concrete rot.
Why Choose Professional Waterproofing Services?
Many homeowners make the mistake of using cheap DIY kits or unlicensed contractors. However, poor workmanship or incorrect membrane application can lead to compliance issues, leaks, and expensive repairs. Hiring a licensed waterproofing expert in Melbourne ensures:
- Full compliance with AS 3740 & AS 4654.2
- Use of high-performance waterproofing membranes
- Correct installation in wet zones and outdoor exposed areas
- Long-term durability backed by warranties
Waterproofing Bathrooms: What You Need to Know
Bathrooms are among the most moisture-prone rooms in any property. Leaks often go unnoticed behind walls and under floors until significant damage occurs.
Key Areas That Need Waterproofing:
- Shower recesses (floors and walls)
- Bathtub surrounds
- Bathroom floors (especially second-storey)
- Wall-to-floor junctions and penetrations
Our Waterproofing Process:
- Surface preparation and priming
- Application of flexible liquid membrane or sheet membrane
- Recoating for thickness and durability
- Final testing and certification
💡 Tip: Ensure your bathroom waterproofing is completed before tiling or floor covering installation.
Waterproofing Balconies: Don’t Let Water Ruin Your Outdoor Living
Balconies in Melbourne homes are exposed to rain, UV radiation, and temperature changes. Without proper waterproofing, water can seep into the structure below and cause:
- Cracks and water damage to ceilings beneath
- Mould, mildew, and swelling of timber joists
- Deterioration of tiles and adhesives
We use UV-stable waterproofing membranes suitable for exposed external applications and apply slope correction to ensure proper water drainage.
Basement Waterproofing: Shielding Your Foundations from Moisture
Basements and subfloor areas are highly susceptible to rising damp and groundwater intrusion. Waterproofing these spaces protects your entire home’s foundation and air quality.
Our Solutions Include:
- Positive-side waterproofing (external)
- Negative-side waterproofing (internal)
- Drainage systems and sump pump installations
✅ Project Highlight: We recently waterproofed a basement in Carnegie, VIC, stopping years of moisture damage in just 3 days.
