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.
