Park Avenue in Sunbury-on-Thames

Crest Nicholson were responsible for the development of Park Avenue in Sunbury-on-Thames, a combination of 193 apartments and spacious executive homes. The site was the old training grounds for London Irish Rugby club.

Methodology

Newton 403 HydroBond was applied to this development to provide a complete waterproof envelope to the structure to provide a Type A (barrier) waterproofing solution suitable for Grades 1, 2 and 3 as defined by BS8102:2009. 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.

  • When placed below a new raft, the poured concrete engages into the locking fleece.

  • Reinforcement steel can be placed on top of the HydroBond ready for the concrete to be placed

  • 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 side. It is suitable for application under reinforced concrete rafts and pre-application to reinforced concrete retaining walls.

Result

HydroBond is suitable for use around below ground reinforced concrete structures, and the self-healing and fully bonded membrane protects the slab from water ingress via shrinkage cracks. Heavy objects can be placed on top of HydroBond. If the membrane is damaged/ punctured by 10mm or more a simple repair can be made by applying a patch and securing with HydroBond tape. Once HydroBond has been laid on to the oversite substrate, reinforcement steel can be placed on top ready for the concrete.
