Brisbane waterproofing contractorsWhy Waterproofing Matters

Leaks in wet areas such as kitchens, bathrooms and laundries can be seriously stress-inducing. When there is inadequate waterproofing or failed waterproofing, water can pool and seep into the foundations of your home.

This can cause a variety of issues such as rot in timbers or concrete, or mould and mildew hidden in wall and floor cavities. When this occurs, often the only recourse is to completely strip the area back, repair the underlying structures and start over.

Costs can easily run into the tens of thousands.

This is why waterproofing matters so much. It is also why you should only engage licensed waterproofing contractors in Brisbane to prepare your home’s wet areas for tiling.

Who Can Waterproof Wet Areas?

Did you know that waterproofing contractors in Brisbane must be fully trained and licensed?

Not just in Brisbane, but across Queensland, waterproofing is covered by specific legislation

Brisbane’s best waterproofing contractorsIn fact, home builds and renovations requiring waterproofing cannot progress until a specialist waterproofing inspector signs off on the waterproofing.

This means that under no circumstances should you DIY your waterproofing. Not only because it requires a very specific skillset but it is also illegal to do so.

There are some exceptions to this rule depending on the value of the works being done.

It is worth noting however that most areas in the home requiring waterproofing would exceed the minimum value outlined by the regulations.

Required Qualifications

To be a qualified waterproofing contractor in Brisbane you must:

  • Have a Certificate III in Construction Waterproofing; and
  • Obtain a license to waterproof from the QLD government. This can only be obtained when proof of relevant qualifications are provided.

The Process Of Waterproofing

Our teams follow a strict procedure when waterproofing that exceeds regulations. They will:

  • prepare the surface to be waterproofed by thoroughly cleaning and removing any debris and ensuring it is completely dry;
  • patch any cracks or gaps and punch in or remove any nails or screws that could compromise the waterproofing;
  • prep surfaces with an appropriate bonding adhesive, one that is best suited for the type of membrane being applied. The membrane is applied and left to dry for between 6-24 hours, depending on the weather and time of year it may take longer; and
  • check the membrane at completion to ensure it is watertight.

Materials Used In Waterproofing

Materials permitted for use by waterproofing contractors in Brisbane are set out in legislation by Australian Standard 3740. They may include:

Liquid – Of which there are three main types.

  1. Water or acrylic-based
  2. Bituminous
  3. Cementitious

Liquid membranes are applied using trowels, rollers or spray guns and are the most versatile option.


Rubber provides flexible, exceptional adhesion as a membrane. These membranes are more common in outdoor spaces.


Self-adhesive sheets with low VOC (volatile organic compound) ratings, making them safer and better for the environment. Sheet membranes deliver excellent waterproofing performance.

The area being waterproofed will determine the type of membrane selected. It is worth noting that 90% of membrane failure occurs as a result of poor preparation of the surface or incorrect membrane choice.

Quality waterproofing contractors in Brisbane, NRA Tiling, can ensure the best preparation, selection, and application of your waterproofing project.
