Part of installing a bath, shower, or building a retaining wall is ensuring that the area surrounding it is properly waterproofed under guidelines from the AS3740 Waterproofing of Wet Areas within Residential Buildings – 2004.
Waterproofing is the process of applying a special membrane or sheeting
Waterproofing is the process of applying a special membrane or sheeting that will protect a surface so that water cannot get through. The bathroom is the largest wet area in most homes so it’s vital that it is done correctly.
This membrane is essential to avoid rotting or warped structural timbers, plasterboard decay, mould, mildew, rising damp, peeling paint, and the corrosion of metal structures.
In fact, poor waterproofing is the most recurring building defect reported by homeowners. Poor installation practices are all to often a significant cause of waterproofing failure. So, you need to use a licensed expert!
At minimum, waterproofing needs to cover the entire bathroom floor and the shower walls up to 1800 mm high. All other walls to at least 150 mm high, and at least 100 mm over the hob or the step down to the floor. This is the minimum standard however so you may wish to go further, waterproofing the walls all the way up for example.
