Wet Area Waterproofing in Practice (AS 3740)
Wet areas leak at the waste, the corners and the doorway, and the waterproofer gets the blame.
Falls, wastes, junctions, the membrane and the flood test before the tiler arrives. How to check the setout and the substrate against the Housing Provisions figures, detail the membrane at every junction, height and termination, and build and cure it to the data sheet. Then prove it with a flood test and keep the record that defends your work when a leak is blamed on the membrane.

Introduction and objectives
Why leaks start at wastes, junctions, penetrations and doorways, and why AS 3740 and Part 10.2 of the Housing Provisions carry the force of the Code.
The Setout: Getting Water to the Drain
Check the 1:80 to 1:50 fall, the 25 mm set-down, the flanged waste, every penetration and the shower threshold before you open a tin.
The Substrate: Prepare It, Prove It or Reject It
Read concrete, screed, sheet and timber floors for clean, sound, primed and dry, and reject an unfit one in writing.
The Membrane: Junctions, Heights, Coats and Cure
Match the bond breaker to the membrane class, measure the 1800, 50, 25 and 5 mm heights, and cure to the data sheet, not the clock.
Proving It and Protecting Yourself
Run a flood test before the tiler, hand over in writing, and keep the folder that answers a claim years after you were paid.
A reused waste and a wet screed
A waste with no flange that leaked for eighteen months, and a wet screed refused in one email that kept a waterproofer out of a claim.
Key takeaways
The habits to take onto your next shower, ensuite or laundry.
Final quiz and certificate
Ten scenario questions, each a decision from a real bathroom. Pass and the certificate goes straight into your dashboard.
Intermediate. For people who already install, prepare for or inspect membranes in domestic wet areas. Covers showers, bathrooms, ensuites and laundries under AS 3740:2021 and Part 10.2 of the ABCB Housing Provisions, from the setout to the handover. It does not cover external or below-ground waterproofing, and it is general education, not legal or insurance advice.
Written for everyone whose work sits on, under or through the membrane.
Licensed waterproofers
When a shower leaks you are the first name in the email, whoever else worked on that floor.
Wall and floor tilers
You work straight onto the membrane, and a knock, a grind or a trowel through it is hidden the moment you tile.
Licensed builders
You set the falls and the programme, and pushing a green screed to suit the tiler is a claim waiting to happen.
Plumbers and drainers
The waste, its flange and every tap and spout penetration are yours, and that is where the water gets in.
Building surveyors
You check falls, hobs, waterstops and the livable bathroom before the tiles hide them.
