when waterproofing gone wrong

A 72-year-old Bayswater grandmother is facing severe health risks due to her government housing unit being infested with toxic black mould for months. Medical professionals have warned against her residing in the property, as the unsafe conditions are exacerbating her serious illness. 

Poor bathroom waterproofing and tiling in Australian homes can lead to leaks, mould growth, and serious long-term health risks. Leaking and mould-affected bathrooms are not just minor issues—they can impact indoor air quality and contribute to respiratory problems, allergies, and ongoing health concerns.

At WA Standard Tiling and Stone, we focus on getting it right from the start—delivering reliable, compliant, and long-lasting solutions you can trust.

Why a Properly Built Bathroom Matters

Why Waterproofing is Critical

Waterproofing is one of the most important parts of any construction project. It protects your home from water damage and ensures long-term durability.

Under Australian Standard AS 3740, all wet areas—including bathrooms, laundries, and toilets—must be properly waterproofed.

Without correct waterproofing, even small amounts of moisture can lead to:

Structural damage

Hidden leaks

Expensive repairs

Getting waterproofing done correctly the first time is one of the smartest investments you can make.
