Description

Newton 402 HydroBond is a high-performance, cold-applied waterproof membrane specifically engineered for the external protection of basement walls and retaining structures. This "Type A" waterproofing solution consists of a thick, highly elastic polymer-modified bitumen layer bonded to a tough, cross-laminated polyethylene film. Unlike pre-applied systems, the 402 is designed for post-application to the exterior of the structure, providing a seamless and flexible barrier that can bridge shrinkage cracks in the concrete. Its self-adhesive backing ensures a secure bond to the substrate, preventing water tracking and protecting the building from groundwater pressure and moisture penetration.

Benefits

  • Fully bonded seamless barrier prevents water from tracking between the membrane and the wall
  • Exceptional flexibility and elasticity allows the membrane to bridge minor cracks in the concrete
  • Cold-applied and self-adhesive for a safer and faster installation without the need for torches
  • Tough cross-laminated carrier film provides high resistance to impact and puncture during backfilling
  • Provides immediate protection against groundwater and aggressive chemicals found in the soil

Good to know

  • Specifically designed for vertical application to the external face of foundation walls
  • Substrate should be primed with Newton 401 Rubberbond Primer for maximum adhesion
  • Should be protected with a drainage layer or protection board before backfilling the soil
  • Available in easy-to-handle rolls for efficient application on site
  • Suitable for use in high water table areas and various ground conditions
