Description

Mapelastic, Mapelastic Smart and Mapelastic Turbo are two-component liquid-applied waterproofing membranes for external applications on substrates under ceramic or stone tile finishes for decks and balconies.

Scope

Mapelastic, Mapelastic Smart and Mapelastic Turbo External Waterproofing Membranes have been appraised as a waterproofing membrane 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.
  • With building structures designed and constructed to meet the requirements of the NZBC.
  • With deck and balcony supporting structures of timber framing with substrates of plywood and fibre-cement compressed sheet.
  • With substrates of suspended concrete slabs.

Mapelastic, Mapelastic Smart and Mapelastic Turbo External Waterproofing Membranes have also been appraised for use as a waterproofing membrane on specifically designed buildings within the following scope:

  • With building structures designed and constructed to comply with the NZBC.
  • With deck and balcony supporting structures of timber framing with substrates of plywood and fibre-cement compressed sheet.
  • With substrates of suspended concrete slab.
  • Subjected to maximum wind pressures.
  • 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 Mapelastic, Mapelastic Smart and Mapelastic Turbo External Waterproofing Membranes must be designed and constructed in accordance with the following limitations:

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

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

The ceramic or stone tile finishes are outside the scope of the Appraisal.

The membranes must be installed by trained applicators approved by Mapei New Zealand Ltd to conditions of the technical data sheet of the products.
