A high performance, self-healing membrane with a locking fleece on the inner surface and a hydrophilic polymer coating externally. The membrane is BDA approved and NHBC accepted as Type A waterproofing.
 
Provided in 1m * 20m rolls with an integral peel-away jointing tape on one side. (Additional spare jointing tape and protection boards avaialble on request).
 
HydroBond 403 Plus provides 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. It is suitable for all below ground and earth-retained structures from domestic basements to the largest civil engineering projects.
 
HydroBond 403 Plus can be used in conjunction with other Newton products to provide a coordinated and combined approach to the waterproofing of the whole structure that includes protection against water ingress to the deck, through construction joints, through and around service entries and to movement joints.
 
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 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 8102:2022.
 
Key Benefits
 
Agrément certified and NHBC accepted waterproofing system.
Forms a full mechanical bond to concrete to prevent water migration between the membrane and the structure.
The hydrophilic layer provides self-healing capabilities when the membrane is punctured.
Very flexible – resistant to movement and fissures in substrates.
Excellent resistance to the high alkalinity of concrete.
Third-party test certification for radon, carbon dioxide and hydrocarbon gases.
The Newton HydroBond™ System completely encapsulates the structure.
