Newton Hydrobond 2K- Flex

When it comes to protecting earth-retaining structures like basements and foundation walls from water damage, there is no room for compromise.

That's why professionals in the construction industry are turning to HydroBond 2K-Flex, a revolutionary bitumen/rubber waterproofing membrane that offers unparalleled strength and flexibility. Newton Hydrobond 2K- Flex

1) Radon Gas Certified: One of the unique features of HydroBond 2K-Flex is its radon gas certification, making it an ideal choice for external waterproofing. Radon gas is a natural radioactive gas that can seep into buildings through cracks and joints in their foundations. Prolonged exposure to radon gas can have serious health implications. By using HydroBond 2K-Flex, you can rest assured that your structure is protected from this silent and invisible threat.

2) Highly Flexible Barrier: Hydrobond 2K-Flex forms a thick and highly flexible barrier against water ingress, offering superb protection against leaks and seepages. Unlike traditional membranes, this innovative solution has the ability to fill voids, cracks, and joints, ensuring a watertight seal. Its flexibility also allows it to accommodate structural movements without compromising its effectiveness, making it a reliable choice for long-term water protection.

3) Two-Component System: HydroBond 2K-Flex consists of two integral components - a bitumen emulsion and a reactive powder. The combination of these components results in a durable and resilient membrane that adheres strongly to the substrate. This two-component system provides a simple and efficient application process, ensuring that the membrane is evenly distributed and adheres seamlessly to the surface.

4) Quick Drying and Rain-Fast: Construction projects often face time constraints and unfavourable weather conditions. HydroBond 2K-Flex addresses both of these challenges. This waterproofing membrane dries quickly, allowing construction activities to resume promptly. Moreover, it is rain-fast after a short period, meaning that even if an unexpected shower occurs during the application process, it won't compromise the effectiveness of the membrane. In conclusion, HydroBond 2K-Flex is a game-changer in the field of external waterproofing. Its radon gas certification, combined with its ability to form a thick, highly flexible barrier against water ingress, makes it the ideal choice for protecting earth-retaining structures. 

With its two-component system and quick-drying properties, it offers convenience and peace of mind to construction professionals. Whether you are working on a basement or a foundation wall, HydroBond 2K-Flex should be your go-to solution for reliable and efficient waterproofing.
