Duroflex 1K

Description

DUROTECH DUROFLEX™ 1K is a high-performance, one-component, fibre-reinforced cementitious waterproofing membrane designed to provide flexible, durable protection across a range of building and construction applications. Formulated with graded aggregates and polymers, it offers excellent adhesion and crack-bridging properties while accommodating significant flexural movement.
Suitable for both positive and negative hydrostatic pressure, DUROFLEX™ 1K can withstand water pressure up to 25 metres of water head (250kPa), making it a versatile waterproofing solution for demanding applications such as retaining walls, planter boxes, swimming pools, rooftops and external balconies.

Key Features:
One-component system – simply add water and mechanically mix.
Fibre reinforced – provides flexibility and improved crack-bridging performance.
Positive and negative hydrostatic pressure resistance – up to 25m water head (250kPa).
Versatile application – can be applied by brush, roller, spray or trowel.
High adhesion strength – suitable for a variety of cementitious and approved building substrates.
Damp substrate application – can be applied to suitably dampened surfaces.
Paintable finish – compatible paints should be confirmed with the paint manufacturer.
Suitable for internal and external waterproofing applications.

Suitable For:
Retaining walls and planter boxes
Concrete swimming pools
Rooftops and external balconies
Podium decks
Concrete shelves
Cement-rendered masonry
Fibre cement sheeting
Concrete substrates
Water-resistant plasterboard
Structural plywood
Applications subject to positive or negative hydrostatic pressure

🔮 ICR Pro Tip.
With cementitious membranes, consistency and thickness are everything. DUROFLEX™ 1K allows you to adjust the water ratio depending on whether you're brushing, rolling, spraying or trowelling, but don't be tempted to add extra water just to make application easier.
Use a wet film thickness gauge as you go to check that each coat is achieving the specified 1mm wet thickness. Apply the second coat at right angles to the first to help achieve consistent coverage and minimise the chance of missed areas.

*One important detail: static cracks must be treated before waterproofing, and live moving cracks must be assessed rather than simply covered with membrane. Always follow the Durotech installation requirements and relevant waterproofing standards.
