Your shower is arguably the most important wet area to have high-quality waterproofing. The chances of water damage in the shower are high if inadequate waterproofing has been installed. In Queensland, there are regulations in place to protect homeowners and tenants from the devastating effects of water ingress. 

It is recommended that you enlist a seasoned professional to complete these services. There are trades that might have a QBCC waterproofing licence, such as plumbers or tilers. However, due to the risks involved, you should hire a qualified waterproofer that is focused solely on the trade.

Your Brisbane Bathroom Waterproofing contractor has specialised experience and is professionally equipped to complete the job. Learn more.

Why Waterproofing Shower Walls and Floors Is So Important

Waterproofing is among the most common building defects reported in Queensland, particularly when it comes to repairing leaking showers and waterproofing shower walls and floors, bathrooms and laundries. This could be due to common misconceptions that concrete cement, bathroom sheets, tile and grout are water resistant. However, grout is actually porous and water flows beneath your tiles as a normal part of bathroom function. 

A waterproofing barrier is required on the floors and walls to prevent water from penetrating these areas and causing structural damage or health complications. Brisbane Bathroom Waterproofing specialises in all of your waterproofing needs. We have renovated over 600 bathrooms and counting.

Legalities Of Shower Waterproofing Brisbane, Gold Coast and Sunshine Coast Buildings

The Building Code of Australia and Australian Standards (AS 3740-1994) have outlined regulations for shower waterproofing in Brisbane & the Gold Coast that all contractors must comply with. 

Here are the relevant requirements for your shower waterproofing:

  • Shower walls must be waterproofed up to 1800mm at a minimum. 
  • The entire shower floor must be waterproofed.

If you are completing a full bathroom renovation, then you are required to comply with the following regulations:

  • Bathroom walls must be waterproofed up to 150mm at a minimum.
  • If there’s a step down, this must be waterproofed up to 150mm. 
  • The entire bathroom floor will need to be waterproofed if the floor material is anything other than concrete.

These standards were created to regulate the process as the risks of inadequate or inexperienced waterproofing are costly to the structural integrity of your home and pose a risk to your health and safety. We work tirelessly to comply with building codes and Australian Standards and go the extra mile by providing an outstanding level of quality and service.
