Newton HydroBond 403 – Safety Data Sheet

Newton HydroBond 403® is a high performance, self-healing, composite sheet membrane, with exceptional waterproofing capabilities and is an effective radon barrier, meeting the performance requirements of BR211:2023. When fitted above the raft support or to wall formwork, the membrane locking fleece is encapsulated into the newly placed concrete, becoming fully-engaged to prevent water 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.
