WUC Internal Waterproofing Checklist

This internal waterproofing checklist helps construction teams verify key steps before and after membrane installation. It covers plumbing rough in, surface preparation free of contaminants, use of approved products such as WPA, Gripset, or Ardex, and compliance with Australian Standards. It guides detailing of pipe penetrations and junctions with polyurethane coves, required waterproofing heights in showers and other areas, coat thickness per application at 0.4 to 0.5 mm, and number of coats per manufacturer guidelines. It includes barricading and protection during curing, confirmation that membranes have cured before follow on works or screeding, and screed falls set to 1 to 100. The template supports photo evidence, comments, and supervisor signature with date.
