Bathroom waterproofing is crucial in order to avoid water damage to your home. As bathrooms are one of the wettest rooms in the house. It goes without saying getting the waterproofing right is vital.  The waterproofing membrane is the barrier which stops water leaking into the structural wall and floor spaces of your home. If your bathroom is not waterproofed correctly, water will seep to the substrate causing damage. Regrettably, some of these leaks are not immediately visible to the naked eye. Until the visible damage has made its presence in the form of peeling paint, rotted timber door frames, water leaks in adjoining rooms and mould.

If you have a shower leak in your existing bathroom. There is no need to rip of the tiles to re-waterproof. Today there are many bathroom waterproofing products on the market. That can fix the bathroom leak without undergoing an expensive rebuild. Waterproofing grout such as epoxy grout will seal the shower and stop the leak.

Bathroom Waterproofing Guidelines

According to insurance companies, bathroom waterproofing failure is the cause for one of the highest number of claims. Creating disputes between insurance companies, builders, and homeowners.

Accordingly, the Building Code of Australia (BCA) has minimum requirements set in place. Bathroom waterproofing must comply to Australian Standards (AS-3740-2010) for domestic wet areas. Needless to say, membranes should always be applied by a qualified and licensed water proofer.  Today many local councils state this as a requirement. Which includes a compliance certificate to be issued by the water proofer upon completion of the job.

Building Code of Australia Requirements (As-3740 -2010)

Waterproofing in the Shower

  • Entire floor of shower recess to be waterproofed
  • Shower walls at least up to 1500mm. The vertical angle between two walls in the shower will need to be waterproofed up to at least 1800mm high
  • At least 100mm over the step down to the bathroom floor or over the shower hob

Bathroom Floor Waterproofing

  • If the bathroom floor is made from or contains timber, plywood, or particleboard. Or the bathroom is on the first floor or higher the entire bathroom floor needs to be waterproofed.

The above are the basic minimum standards as per the code which was updated in 2010. However, it should be noted that these standards are always being updated.

In addition to the minimum standards. The updated regulations apply to all new bathrooms and bathroom renovations within Australia.

They include the following requirements

  • The type of waterproofing materials to be used. The materials must be able to withstand movement & exposure to cleaning products and alkali found in cement mortar.
  • Flashing must be used in all wet areas of the bathroom, including around toilets.
  • Frameless shower screens require a full floor waterproofing system or 1.5m radius from the showerhead.
  • A water stop must be installed in all wet-area doorways.
  • Tap washers must be able to be changed without disturbing waterproofing seals.

All things considered although these are the minimum requirements. It is always a good idea to go beyond the minimum requirements to save yourself heartaches down the track. When doing bathroom waterproofing this is no time to skimp to try to save on costs. Cutting corners or using inferior products will in the end cause bigger problems down the track.
