Waterproofing Inspection and Test Plan template
A failed membrane shows up months later behind the tiles. A flood test photo with a time on it is the strongest proof you can keep.

Run it in OzHub
Take a photo at each checkpoint inside the app. OzHub records the time from our server and the place from the phone, keeps a fingerprint of the photo, sends hold points to your manager, and gives your client a link to approve. Read more on the ITP app page.
General information only. Follow your project specification, engineer, certifier and the relevant Australian Standards. See the disclaimer.
Questions
What is an ITP for waterproofing work?
An Inspection and Test Plan lists the checks, tests and sign-offs needed on waterproofing work, in order. Each line is a checkpoint: a hold point (work stops until approved), a witness point (the client may attend) or a review check.
Which waterproofing checkpoints are hold points?
Hold points in this template: Cure time respected, then flood test; Inspection before tiling; Flood test before cover.
Can I edit this template?
Yes. In OzHub you can copy a template, add or remove checkpoints and change which ones are hold or witness points. Your project specification and engineer come first.
Does my client need the app?
No. They get a private link by email, see the checkpoints and photos, type their name and approve or reject. No app or login.
