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

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 European PVC standards.

The Wolfin Membrane system comprises of a single layer homogenous/uniform (not 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.

Wolfin Membranes have been regularly used for the waterproofing of Residential, Commercial & Industrial applications including:

  • Planter BoxesPillar-Tank
  • Roofs, Green Roofs & Landscaped Areas (FLL Certified)
  • Balconies
  • Decks
  • Podium Slabs
  • Terraces
  • Basements
  • Lift Pits
  • Potable Water Tanks
  • Detention, Retention, Header & Dump Tanks

The membranes are suitable for most applied finishes installed over them including tiles, wearing slabs, pavers on pads, landscaped areas and can be installed over damp substrates.

Wolfin membranes can be applied to most substrates including concrete, timber, steel, CFC, masonry blockwork etc. All junctions & overlaps of the membrane are hot air welded, UV stable, suitable for recycling and have exceptional chemical resistance.

Every Wolfin installation is inspected & signed off by Wolfin Membranes Australia resulting in a Single Point Warranty on Labour & Materials issued to the building owner.
