- Self-Healing Technology: HydroBond 403 features a self-healing composite sheet membrane that automatically seals small punctures, ensuring continuous waterproofing protection.
- Full Engagement with Concrete: The locking fleece becomes fully integrated into newly placed concrete, preventing water from tracking and ensuring long-term durability.
- Comprehensive System Integration: As part of the HydroBond® System, HydroBond 403 offers complete waterproofing solutions, including post-applied membranes and drainage boards, suitable for various below-ground and earth-retained structures.
- Certified Durability: Supported by BDA Agrément Certificate and accepted by NHBC, HydroBond 403 provides a durable waterproof barrier for the life of the building, with an expected lifespan of at least 60 years.
Newton HydroBond 403 is a high-performance, self-healing, composite sheet membrane, with exceptional waterproofing capabilities. When fitted above the raft support or to wall formwork, the locking fleece is encapsulated into the newly placed concrete, becoming fully-engaged to prevent water from tracking.
If the waterproof LDPE layer is punctured, the exposed hydrophilic coating expands, preventing water ingress, effectively sealing small holes that may be accidentally formed during fixing of the reinforcing steel or the placing and compaction of the concrete.
HydroBond 403 is a component of the HydroBond® System that also includes post-applied waterproofing membranes, protection and drainage boards, providing a complete waterproof envelope to the structure to achieve Type A (barrier) waterproofing suitable for Grades 1, 2 and 3 as defined by BS 8102:2022. The HydroBond System is suitable for all below-ground and earth-retained structures from domestic basements to the largest civil engineering projects.
Correctly protected, the Newton HydroBond System will provide, under normal service conditions, a durable waterproof barrier for the life of the building to which it is installed; the expected lifetime of the building itself should be at least 60 years. The Newton HydroBond system is supported by BDA Agrément Certificate BAB 17-031/04/A and is accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 & 3 according to BS 8102:2022.
