...setting best practice in waterproof membranes...

Welcome

Welcome to the website of the Waterproof Membrane Association Inc (WMAI), recently renamed from the Membrane Group New Zealand Inc.

The WMAI is a group of companies in New Zealand who have an interest in membranes used for waterproofing applications.  Membership includes manufacturers, importers and applicators, and is open to any interested party.

Our purpose is to develop and promote a suite of Codes of Practice that cover the following types of membranes: 

  • Torch-on
  • Liquid-applied
  • Self-adhesive 

 The suite of Codes will include the following applications for membranes: 

  • Internal or external
  • Above or below ground
  • Roofing or decking
  • Trafficable or non-trafficable

 We aim to set the benchmark for best industry practice in relation to waterproof membranes.
