HydroBond External Waterproofing Membrane
Newton 403 HydroBond is a high performance external waterproofing membrane. It provides a Type A (barrier) waterproofing solution to below ground and earth-retained structures.
How the HydroBond Membranes Works
One side of the membrane features a locking fleece and the other a polymer hydrophilic.
The fibres of the locking fleece allow the membrane to form a full mechanical bond with the concrete. This stops water tracking between the membrane and the structure when placed below the new raft or against permanent or temporary timber wall formwork.
The hydrophilic coating expands when it comes in contact with water. This allows it to seal small holes that may be formed during construction. This self-healing property deals with accidental punctures, providing peace of mind.
Newton 403 HydroBond can be used with other Newton products in order to waterproof a whole structure. Once correctly installed, it provides complete protection for the life of the building against water ingress. This includes the deck, through construction joints, through and around service entries and to movement joints.
Applications of HydroBond
The HydroBond is suitable for all below ground and earth-retained structures. It is ideal for every job from domestic basements up to large civil engineering projects.
HydroBond 403 can be used as a continuous membrane on permanent raft and wall formwork. This includes raft blinding and piled walls of reinforced concrete earth-retained structures.
It is suitable as raft or slab for the following substrates:
- Concrete blinding
- Compacted type 1 hardcore
- Compacted sand

Can Newton 403 Hydrobond be used internally?
No, Newton 403 Hydrobond is designed to be applied to the outside of the structure or under the slabbefore the slab is poured.
Is Newton 403 Hydrobond self adhesive?
Newton 403 is not self adhesive, it is designed to bond to poured concrete when it is poured over or against it wet. The concrete dries and bonds to the fleece side of the Hydrobond.
