Newton HydroBond 2K-Flex – Advanced Flexible Waterproofing for Earth-Retaining Structures
Newton HydroBond 2K-Flex is a highly flexible, two-component bitumen/rubber waterproofing membrane designed for external waterproofing of basements, foundations, and earth-retaining structures. This environmentally friendly, solvent-free system forms a seamless, fully bonded barrier that effectively prevents water ingress and radon gas penetration, ensuring long-lasting protection.
By combining polymers, polystyrene fillers, and a reactive powder, HydroBond 2K-Flex chemically reacts upon mixing to create a thick yet highly flexible waterproofing layer. It easily fills voids, cracks, and joints, adapting to substrate movements for superior crack bridging. Application is effortless with a trowel or airless spray machine, making installation quick and efficient.
Key Benefits:
✅ Thick, seamless waterproofing membrane – Fully bonded for long-term durability
✅ Excellent crack bridging – Bridges cracks up to 2mm due to polymer and polystyrene modification
✅ Quick-drying & rain-fast – Ensures rapid protection after application
✅ Solvent-free, non-toxic & odourless – Safe for both indoor and outdoor use
✅ Non-flammable & VOC-free – Eco-friendly formulation
✅ Radon gas resistant – Certified for gas-proofing applications
✅ Sprayable for large-scale application – Efficient for extensive waterproofing projects
✅ Adheres insulating panels to concrete & masonry – Provides strong bonding to various substrates
Typical Applications:
✔ Continuous Type A waterproofing & radon protection (used alongside Newton HydroBond® pre-applied membranes)
✔ Basements, foundations & earth-retained walls – Fully waterproof & radon-resistant
✔ Smoothing of irregular surfaces before applying bitumen-based membranes
Coverage & Application Requirements:
To comply with DIN 18195, Class W2.1-E, HydroBond 2K-Flex must be applied in two coats to achieve a 4mm cured film thickness.
-
Wet application rate: 5.6 litres/m²
-
Total dry/cured membrane thickness: 4mm
A 30L tub (plus ancillaries) provides a typical coverage rate of 5.6L/m².
Required Ancillary Products:
🔹 HydroBond 2K-Flex Primer (HB-2KP) – Enhances adhesion & reduces substrate porosity (Not required for ICF)
🔹 HydroBond 2K-Flex Mesh (HB-2KM) – 160g/m² fiberglass reinforcement mesh with alkaline-resistant latex coating
