IZOTEX ULTRA Waterproofing Membrane Download Document


3 layers vapour retardant waterproofing membrane consisting of PES/PE/PES layers with an enhanced bonding surface. It protects floor and wall substrates from water penetration and moisture passage in wet areas.


  • The special fleece lining on both sides creates enhanced bonding surface and make the membrane compatible with all kinds of adhesive except solvent based adhesives.
  • ULTRA can be used in both indoors and outdoors.
  • ULTRA allows an optimum surface for tiling after it is installed.
  • Due to its flexible structure there will be no crack on the membrane in time.
  • ULTRA protects the substrate from the water leakage that comes from the joint gap, crack or fracture of the covering material.
  • It is easy to work with, it can be cut by scissors.
  • It does not pose risks in terms of work safety during the application.

IZOTEX ULTRA Waterproofing Membrane


ULTRA is used to provide waterproofing and damp proofing under ceramic tiles on wet room’s floors and walls. The membrane is used to provide waterproofing under covering materials (marble, covering concrete etc.) on terraces.

ULTRA is used as a moisture barrier in floor heating systems to block the vapour formation. It is laid beneath floor heating systems to prevent the system from the moisture comes from the substrate.
