Description

Gripset 38® and Gripset® 2P External Waterproofing Membranes are liquid-applied waterproofing membranes for use under ceramic or stone tile finishes on external decks and balconies.

Scope

Gripset® 38 and Gripset® 2P External Waterproofing Membranes have been appraised for use as waterproofing membranes for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
  • with timber supporting structures designed and constructed in accordance with the NZBC; and,
  • with a substrate of fibre cement compressed sheet; and,
  • with decks that have a maximum size of 40 m2 ; and,
  • situated in all Wind Zones of NZS 3604 up to, and including, Extra High.

Gripset® 38 and Gripset® 2P External Waterproofing Membranes have been appraised as waterproofing membranes for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with regard to building height and floor plan area; and,
  • with building structures subject to specific engineering design; and,
  • with deck and balcony supporting structures of timber framing with a substrate of fibre cement compressed sheet; or,
  • with a substrate of suspended concrete slab; and,
  • situated in all Wind Zones of NZS 3604, up to and including Extra High.

Gripset® 38 and Gripset® 2P External Waterproofing Membranes have also been appraised for use as waterproofing membranes on specifically designed buildings within the following scope:

  • with building structures subject to specific engineering design; and,
  • with deck and balcony supporting structures of timber framing with a substrate of fibre cement compressed sheet; or,
  • with a substrate of suspended concrete slab; and,
  • subjected to maximum wind pressures (Refer Paragraph 7.8); 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.)

This Appraisal is limited to decks and balconies within the following scope:

  • constructed to suitable falls (Refer Paragraph 12.4 - 12.9); and,
  • with the membranes continually protected from exposure to UV (ultra violet) light and from physical damage by ceramic or stone tile finishes on a pedestal or ABS uncoupling system; 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.

Building structural 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 are specific to each building, and are therefore the responsibility of the building designer and building contractor and are 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 Waterproofing Systems NZ Ltd.
