Externally Applied Waterproofing Membrane and Gas Barrier Variant
Newton 403 HydroBond is a very high performance composite sheet membrane that features a locking fleece to one side and a polymer hydrophilic coating to the other. The Newton 403 HydroBond-GB variant also includes LDPE and aluminium layers to resist radon, carbon dioxide and hydrocarbon gases.
When placed below the new raft or against permanent or temporary timber wall formwork, the fibres of the fleece inner core are encapsulated into the concrete, forming a close and intimate bond. The membrane becomes fully-engaged into the concrete to prevent water tracking and is suitable for all below-ground and earth-retained structures, ranging from domestic basements to the largest civil engineering projects. The hydrophilic coating expands when in contact with water and seals small holes that may be accidentally formed during fixing of the reinforcingsteel or the compaction of the concrete.
Agrément certificated waterproofing system
NHBC accepted waterproofing system
Full mechanical bond to concrete prevents water migration between membrane and structure
Hydrophilic coating provides self healing of punctures to the membrane
Very flexible – Resistant to movement and fissures in substrates
Applied under the raft and to the walls to fully encapsulate the structure
Excellent resistance to the high alkalinity of concrete
Third-party test-certification for radon, carbon dioxide and hydrocarbon gases
As a continuous membrane to the underside of the raft and the outside of the walls to reinforced concrete and earth retained structures.
When placed below the new raft or against permanent shuttering, the Newton 403 HydroBond fibres are encapsulated into the wet concrete, becoming monolithic to the surface. The fully engaged membrane prevents water tracking to the joints in the structure, should there be a defect.
Newton 403 HydroBond self-heals to seal around penetrations
The hydrophilic coating expands by approximately 150% when in contact with water and seals small holes that may be accidentally formed during fixing of the reinforcing steel or the pouring and compaction of the concrete.
Newton 403 HydroBond is applied as an external barrier to water ingress to provide Type A (barrier) waterproofing as defined by BS 8102:2009 and is applied to the blinding prior to the concrete pour of raft foundation structures, and then to the formwork, permanent or temporary, for the construction of the retaining walls.
All below ground and earth retained structures, ranging from domestic basements to the largest civil engineering projects, can be waterproofed with Newton 403 HydroBond.
Pre-construction prior to concrete pour:
Clay Heave Boards.
Permanent and removable formwork.
Newton 410 Geodrain drainage membrane.
Adjacent substructures as permanent formwork.
Piled cut off walls.
Newton 403 HydroBond provides a complete waterproof envelope to the structure to provide a Type A (barrier) waterproofing solution for Grades 1, 2 and 3 as defined by BS 8102:2009. Newton 403 HydroBond can be used with other Newton products to provide a co-ordinated and combined approach to the waterproofing of the structure that includes protection against water ingress to the deck, through construction joints, through and around service entries, and to movement joints.
Newton 403 HydroBond is supported by BDA Agrément Certificate BAB 16-031/03/A
Correctly protected, the Newton HydroBond System will provide, under normal service conditions, a durable waterproof covering for the life of the building to which it is installed; the expected lifetime of the building itself should be at least 60 years, and is supported by BDA Agrément Certificate BAB 16-031/03/A and is accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 & 3 – BS 8102:2009.
“Newton HydroBond is a very robust, unique and easy to install system. Newton Waterproofing Systems provide training and back up where needed, which ensures the product is installed correctly, and makes certain that the final structure is fully waterproof. The directors and staff at Newton are helpful, friendly and very co-operative. I would not hesitate to recommend this superior product to our clients on future developments” – Paul Dennison, Director, Buxted Construction (Project: Park Avenue Housing Development, Sunbury-On-Thames)
“Newton HydroBond and FlexProof were installed in sub-zero temperatures in a demanding location – they were easy to install and kept the project on track” – Nigel Cleeve, Acrabuild (Project: Windfarm Substation)
“Newton 403 Hydrobond is our system of choice for pre-applied waterproofing because our experienced operatives find it is quick to install and easy to detail compared to all of the many other systems they have used.” – Ian MacLennan, MacLennanUK (Newton Specialist Basement Contractor)
