Emer Proof Ecoseal

Next generation solvent free polyurethane membrane.

Emer-Proof EcoSeal is a next-generation solvent-free polyurethane membrane designed for a wide range of waterproofing applications in the built environment. This single component membrane offers high performance elastomeric and tensile strength properties, along with excellent elastic recovery.

Emer-Proof EcoSeal is an alternative to solvent-based and moisture-curing polyurethane membranes for areas exposed to permanently wet conditions. It offers outstanding low water vapour transmission properties.

It is suitable for internal and external wet areas, enabling the direct fix of ceramic tiles, screeds, and renders over the dried membrane without the bonding issues that solvent-based polyurethane membranes present.


Emer-Proof EcoSeal is suitable for a wide range of waterproofing applications, such as:

  • Wet areas and shower alcoves – Class III Membrane System
  • Podiums, terraces, balconies and deck areas – under toppings, tiles and other finishes
  • Foot trafficable exposed rooftop membrane (when over-coated with Emer-Proof Top Coat)
  • Foot trafficable exposed balcony decks (when over-coated with Emer-Proof Top Coat)
  • Foot trafficable exposed walkways, subject to regular foot traffic (when over-coated with Emer-Proof Top Coat)
  • Sandwich seal between existing and new substrates, e.g. old to new concrete; cement screeds over concrete and CFC surfaces
  • General areas exposed to moisture and damp conditions


  • Low VOC (6 grams per litre)
  • Australian made
  • Can be flood tested after 24 hours @ 23oC
  • Elastomeric and flexible with excellent elastic recovery
  • Will not re-emulsify once cured. Handles permanently wet conditions
  • Low water absorption
  • Low water vapour transmission properties
  • Excellent adhesion to primed surfaces
  • Compatible bonding properties for tile adhesives (such as Emer-Proof Tilebond Flex), screeds and renders
  • Solvent-free and non-hazardous
  • Excellent chemical resistance

Standards Compliance

Emer-Proof Undertile meets the requirements of:

  • AS/NZS 4858:2004 Wet Area Membranes as a Class III membrane
  • AS3740: 2010 Waterproofing of Wet Areas Within Residential Buildings
