Waterproof decks – membrane turn-ups improperly installed

Cause

Poor detailing and/or installation to membrane turn-ups at walls and doors (potentially allowing water entry)

Repair

  • contact a specialist applicator to remove and reinstall/replace the membrane properly with 150 mm turn-up under cladding (this may require the removal of some cladding) and gussets installed at internal corners
  • where it is suspected that the building may be leaking and there is a risk of damage, engage a building surveyor to report on the building and advise on repair/replacement options.

Cause

The waterproofing membrane was applied/laid after the cladding was installed
