Newton HydroBond 403 GB – Safety Data Sheet

Newton HydroBond 403 GB® is a high-performance, self-healing, composite sheet membrane with exceptional waterproofing capabilities, that also provides ground gas resistance (in compliance with BS 8485:2015+A1:2019). When fitted above the raft support or to building line 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 and effectively sealing small holes that may be accidentally formed during fixing of the reinforcing steel or the placing and compaction of the concrete.
