PDQ Poly | World Class Waterproofing Sheet Membrane

AUSTRALIAN MADE
SUSTAINABLE WATERPROOFING

East Melbourne, VIC

Formulated in our state-of-the-art Melbourne facility,

PDQ Poly waterproofing sheet membranes combine a premium acrylic coated PVC with a unique self-adhesive and fibreglass mesh composite that is eco-friendly and durable.

This advanced formulation provides reliable protection against black mould, hydrolysis, thermal movement and reflective cracking.

PDQ Poly is available in three versions:

Independently tested, PDQ Poly sheet membranes meets or exceeds Australian Waterproofing Standards AS 4858 and AS 4654.1, and meet ISO 16000-9 standards for indoor air quality. When installed in accordance with AS 3740 and AS 4654.2, PDQ Poly also outperforms liquid membranes, making it the trusted choice for reliable, long-lasting waterproofing.

INDUSTRY LEADING STRENGTH

Recognised as the strongest sheet membrane in the world,

PDQ Poly sets a new benchmark for durability. Its incredible

30 MPa pull resistance gives it more strength than any other membrane on the market, allowing a standard 10 metre roll to withstand up to 30 tonnes of force. Even under extreme pod or pedestal point-loading, PDQ Poly remains unaffected.

NON-TOXIC MOULD PROTECTION

Using a natural ion-based system, PDQ Poly provides built-in protection against black mould, mildew, and bacteria. Micronised zinc offers broad-spectrum antibacterial defence, while micronised copper delivers powerful antifungal protection — all in a non-toxic, safe formula that avoids the risks of traditional biocides.

INFINITE APPLICATIONS

Unparalleled in versatility, PDQ Poly is the ideal choice for both new construction and remedial projects. It performs flawlessly in a wide range of environments, from internal wet areas such as balconies and bathrooms, to external applications including roofs, roof gardens, and planter boxes, as well as challenging below ground situations such as retaining walls.
