WPA 1

Water-based Waterproofing Membrane

WPA 1 is a high-performance, elastomeric waterproofing membrane developed for professional waterproofing applications. Its advanced water-based polyurethane technology provides a versatile solution for under-tile, fully exposed and subterranean waterproofing systems.

​

Suitable for internal wet areas, balconies, terraces, rooftops, podium decks, planter boxes and below-ground applications, WPA 1 combines rapid drying and curing properties with excellent adhesion, weather resistance and UV resistance. Its Class III performance helps the membrane accommodate movement while maintaining a durable waterproof barrier.

​

• Class III membrane in accordance with AS/NZS 4858 and AS 4654.1

• Conforms to ISO 13007.5

• Rapid drying and rapid curing properties

• Built-in root inhibitor

• Low VOC content

• Excellent adhesion properties

• Non-hazardous and solvent-free

• Excellent weather and UV resistance

A Versatile Membrane for Professional Waterproofing

​

WPA 1 can be incorporated into waterproofing systems across a range of residential, commercial and construction applications. Its versatility allows waterproofing professionals to use one high-performance membrane across under-tile, exposed and below-ground environments, subject to the specified system requirements.

​

The water-based formulation, rapid curing characteristics and strong adhesion make WPA 1 a practical option where reliable application and long-term waterproofing performance are required.

Where Can WPA 1 Be Used

​

WPA 1 is designed for a broad range of waterproofing applications, including:

​

• Internal wet areas, including bathrooms, showers, kitchens, laundries and toilets

• Balconies, terraces, rooftops and podium decks

• Under-tile and approved fully exposed waterproofing applications

• Planter boxes and landscaped areas where root resistance is required

• Retaining walls and below-ground waterproofing applications

• Residential, commercial and specified waterproofing projects

Always refer to the current WPA 1 Technical Data Sheet for approved substrates, surface preparation, application requirements and system limitations.
