The membranes are a unique combination of Polyester/PVC, which exhibit excellent characteristics including:

  • excellent chemical resistance
  • up to 350% elongation
  • bitumen compatible
  • root resistant-testedRoof-Waterpoofing

For more than five decades Wolfin membranes has counted among the leading manufacturers of waterproofing systems worldwide. The formulation has remained unchanged through this time & is regulated and monitored by external institutes to ensure it meets both European PVC standards and the Australian Standard for waterproofing membrane materials (AS4654.1-2012) and waterproofing design & installation (AS4654.2-2012).

The Wolfin Membrane system comprises of a single layer homogenous/uniform (non laminated) sheet membrane, combined with factory bonded steel profiles, cast in reglets, pre-made corners & PVC welding solvent to create “The Complete Waterproofing System”.

All Wolfin products are designed to meet the highest demands for buildings and provide maximum long-term water protection for the structure.  Wolfin has been extensively used in Australia since the late 1980’s & covered millions of square metres in all climatic zones of our planet.
