Waterproofing Defects

BCA and NCC cover this under the Australian Standard AS3740-2010


This can be undertaken internally in Wet areas only by a licenced Wall and Floor tiler, Waterproofing Contractor and a Builder who is competent in the use of these products.

All of the above can certify this installation.

Wet Areas are the Toilet, Bathroom, Laundry and En-suite.

Waterproofing and tiling defects in wet areas are usually closely aligned since they fall into the top 4 categories of Construction failures regularly.


This is any area outside of a deemed Wet Area in the house or garden or any other structure that has been deemed an area which should be Watertight and these could include behind retaining walls and Concrete roofs.

Stormwater, Geotechnical fabrics and panels product installation in relation to waterproofing behind walls where hydrostatic pressure may build up is also a key factor in the failure or success of most areas.

I can also provide information for Non-invasive and invasive repair works based on my knowledge of the Industry and the products available.(Scope of work)
