Description

Wet-seal DS411 Exterior Waterproofing Membrane is a single part waterproofing membrane for use under ceramic or stone tile finishes on external decks and balconies.

Scope

Wet-seal DS411 Exterior Waterproofing Membrane has been appraised as waterproofing membranes on buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with respect to building height and maximum floor plan areas; and,
  • with building structures designed and constructed to meet the requirements of the NZBC; and,
  • with deck and balcony supporting structures of timber framing with substrates of plywood; and,
  • with substrates of suspended concrete slabs; and,
  • situated in all Wind Zones of NZS 3604, up to and including Extra High'.

Wet-seal DS411 Exterior Waterproofing Membrane has also been appraised for use as waterproofing membranes on specifically designed buildings within the following scope:

  • with building structures designed and constructed to comply with the NZBC; and,
  • with deck and balcony supporting structures of timber framing with substrates of plywood and fibre cement compressed sheet; and,
  • with substrates of suspended concrete slab; and,
  • subjected to maximum wind pressures; and,
  • with the weathertightness design of all junctions being the subject of specific design by the designer.

Note: The design of these junctions has not been appraised by BRANZ and is outside the scope of this Appraisal.

Decks and balconies waterproofed with Wet-seal DS411 Exterior Waterproofing Membrane must be designed and constructed in accordance with the following limitations:

  • constructed to suitable falls; and,
  • with the membranes continually protected from exposure to UV (ultra violet) light and from physical damage by ceramic or stone tile finishes; and,
  • with decks and balconies designed and constructed such that deflections do not exceed 1/360th of the span; and,
  • with no steps within the deck level, no integral roof gardens and no down pipes discharging directly onto the deck.

Movement and control joints in the substrate must be carried through to the tile finish. The design and construction of the substrate and movement and control joints is specific to each building, and therefore the responsibility of the building designer and building contractor and is outside the scope of this Appraisal.

Ceramic or stone tile finishes are outside the scope of this Appraisal.

The membranes must be installed by trained applicators, approved by Wet-seal New Zealand Ltd.
