Gripset® 38FC and Gripset® 2P Wet Area Membranes

Description

Gripset® 38FC and Gripset® 2P Wet Area Membranes are liquid-applied waterproofing membranes for use under vinyl, ceramic or stone tile finishes in internal wet areas.

Scope

Gripset® 38FC and Gripset® 2P Wet Area Membranes have been appraised for use as waterproofing membranes for internal wet areas of buildings within the following scope:

  • On floor substrates of concrete, compressed fibre-cement sheet and fibre-cement sheet tile underlay and on wall substrates of concrete, concrete masonry, wet area fibre-cement sheet lining systems and wet area plasterboard lining systems.
  • When protected from physical damage by vinyl, ceramic or stone tile finishes.
  • Where floors are designed and constructed such that deflections do not exceed 1/360th of the span.

The use of Gripset® 38FC and Gripset® 2P Wet Area Membranes on concrete slabs where hydrostatic or vapour pressure is present from below is outside the scope of this Appraisal.

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.

The vinyl, 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.
