Waterproofing in Adelaide
Waterproofing is the invisible work that protects a home from the most expensive damage there is — water getting into the structure. In SA, wet-area waterproofing is regulated under AS 3740, and getting it wrong (or skipping it to save money) leads to rot, mould, and repair bills in the tens of thousands. This page covers waterproofing for showers, bathrooms, balconies, and the certification you need.
Why waterproofing matters so much
The cost of proper waterproofing is tiny compared to the cost of failure. Water that gets behind tiles or under a balcony rots framing, spreads mould, and damages rooms below — often $10,000+ to remediate. It's the definition of a job worth doing right the first time.
AS 3740 and certification
SA wet-area waterproofing must comply with AS 3740. A certified waterproofer should issue a Certificate of Waterproofing on completion — essential for insurance claims and property resale. Always confirm your waterproofer is certified and provides documentation.
