Newton Hydrobond 2K-Flex

The Newton Hydrobond 2K-Flex is a revolutionary and highly flexible waterproofing solution designed specifically for external waterproofing of earth-retaining structures such as basements and foundation walls. This product is a 2-component bitumen coating that combines the benefits of polymers, polystyrene fillers, and environmentally friendly properties.

Certified to effectively seal out radon gas, this innovative bitumen/rubber membrane forms a thick and impenetrable barrier to water ingress. Its flexibility allows it to adapt and fill voids, cracks, and joints, ensuring a watertight seal even in challenging conditions.

What sets the Hydrobond 2K-Flex apart is its solvent-free and environmentally friendly composition. Made of a bitumen emulsion and a reactive powder, these two components chemically react upon mixing to produce a firm yet highly flexible coating. This reliable coating can be applied effortlessly by trowel or airless spray machine, making installation a breeze.

In addition to its excellent waterproofing performance, the Hydrobond 2K-Flex can also effectively adhere insulated panels to concrete, masonry, and thoroughly dried thick bituminous surfaces. This versatility ensures that it can be used in various applications to provide a seamless and reliable waterproofing solution.

When it comes to protecting your earth-retaining structures, trust the Newton Hydrobond 2K-Flex to deliver superior waterproofing capabilities. Don't compromise on quality – choose a product that has been specifically designed to provide long-lasting protection and peace of mind.

Coverage

To comply with DIN 18195, class W2.1-E, the membrane must be of two coats to a total thickness of 4 mm, with the first coat reinforced with mesh. To achieve a 4 mm
cured film, a wet application of 5.6 litres/m² is required.

• Two coats
• Total application rate of 5.6 litres/m²

Dry/cured membrane thickness of 4 mmNewton HydroBond 2K-Flex is also a constituent product of the Newton HydroBond®System for Type A Waterproofing to Grades 1a,1b, 2 and 3 - BS 8102:2022. 1Nr 30L Tub plus ancillaries achieves a typical coverage rate of 5.6L/m2.

Required Ancillary Products

• Newton HydroBond 2K-Flex Primer - Bonding agent that also lowers porosity of concrete and masonry substrates. Not required for ICF.
• Newton HydroBond 2K-Flex Mesh - 160g/m2 reinforcing mesh which is made from woven fibreglass yarns and coated with an alkaline resistant latex which prevents the alkaline present in cement from degrading the glass fibre.
