The membrane looked at while it is still a membrane and not a floor.
The Oran Park wet area findings centre on the flange at the floor waste and on protecting the membrane once it is down. A membrane is a coating, not armour: trades walking on it, leaning ladders on it or dropping tools on it will damage it, and the damage is under tile within days. We record both the flange detail and whether the finished membrane has been protected before the tiler starts.

Covering it so the trades who come next do not walk on, scuff or puncture it. It is ordinary site practice and it is skipped often enough that we look for it specifically.
Because it is the junction between the membrane and the drain, and a junction is where continuous layers stop being continuous. Get it wrong and water reaching the membrane never reaches the waste.

No. A flood test disturbs completed work and forms part of the waterproofer's own checks.
In the gap after the membrane cures and before tiling starts, which is often only a couple of days.
We look at whatever is still exposed and note which areas had already been closed up.
