Worth knowing: getting two or three quotes is the simplest way to land a fair price — and it costs you nothing.
Licence number. On the quote, and verify it before work starts.
Compliance certificate. An AS 3740 certificate promised before tiling starts.
Membrane brand. The exact membrane product, not just 'waterproofing'.
Substrate preparation. Grinding, priming and levelling, so nothing is skipped.
Number of coats. Liquid membranes need at least two coats.
Flood testing. A 24-hour flood test before the tiles go on.

Things that can impact your job
These factors affect waterproofing work in this area — worth discussing with your tradie.

Cooler Months Give Better Results
