The membrane inspected while it is still a membrane and not a floor.
Pinholes dominate the Marsden Park wet area set: eleven separate records across these jobs, in shower recesses, niches and at the main drain. A pinhole is a break in the applied membrane about the width of a pen tip, usually a burst bubble in the coat or debris trapped beneath it. Alongside them, bond breaker tape at junctions, upturn heights and the membrane left unprotected before the following trades arrive.

A break in the applied membrane roughly the width of a pen tip. It is a hole in a layer whose entire job is to have none.
Close visual inspection across the whole membrane with light, rather than a walk through the room. It is slow, which is why the stage is worth booking on its own.
At a junction where two surfaces move against each other, it lets the membrane span the joint instead of being bonded to both sides and tearing.

No. A flood test cuts into completed work and forms part of the waterproofer's process, not ours.
We examine what remains open and record the areas already covered.
