Waterproofing is a critical element of a bathroom renovation. Water leaks can cause damage to the building structure, fixtures and finishes if it penetrates into the walls or floor.
Without proper waterproofing, water can penetrate the substrate causing mould and mildew to develop and potentially lead to health issues. Framing and walls are particularly susceptible to water damage. Additionally, inadequate waterproofing can cause tiles or grout to deteriorate, flooring to warp and rot and paint to peel.
In order to prevent these problems, we apply waterproofing to meet Australian Standards AS3740-2021.
Waterproofing a wet area requires applying a continuous, flexible membrane to floors and walls. Essential steps to creating a waterproof barrier include thorough cleaning of all surfaces, applying a primer, applying bond breaker to corners, and two coats of waterproof membrane. The membrane will typically need to cure for more than 24 hours before tiling work is commenced.

Waterproofing is necessary to ensure the ongoing structural integrity of wet areas in a bathroom or other wet area and to minimise issues associated with mould, or other damage caused by swelling or cracking. It is important to use high-quality materials at all stages of the waterproofing process: primer, sealants, bandage, waterproofing membrane and final bathroom caulking silicone. Waterproofing conducted by a qualified and experienced bathroom renovation team will ensure a lasting finish. Waterproofing is done to both floors and walls according to Australian standards and is best done by a licensed professional. It is essential to waterproof before tiling and installing shower bases and bathtubs.
The standards for waterproofing in Australia are set out under the regulations in AS 3740:2021. This standard for domestic use sets out the minimum specifications for the design and installation of waterproofing and the materials used. Waterproofing is a highly technical and essential element in quality and lasting bathroom renovations.
Waterproofing costs depend on the size and complexity of the job. In general terms waterproofing costs approximately $40 per square metre. The total cost will generally start at about $650 but may be as much as $3000 to $4000.
Re-waterproofing can be a more complex job as it is necessary to fix the underlying causes and structural damage before any other works can be attempted. A qualified waterproofer will be able to give you a quote and discuss the best approach to repairs.
