  • Waterproofing and radon protection of basement walls as part of the Newton HydroBond System.
  • Standalone waterproofing membrane for basement, foundation and earth-retained walls.


Newton 108 HydroBond-LM is a highly radon resistant, cold spray-applied, seamless, rubber waterproofing membrane for the external waterproofing of basements and foundation walls. Normally specified as part of the HydroBond® System in conjunction with Newton 403 HydroBond. The membrane can however also be used on its own, terminating to raft or strip foundations.

It is extremely puncture resistant, with a high elasticity and a 95% recovery memory. The membrane becomes fully engaged into the concrete surface 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.

Newton 108 HydroBond-LM can be used together with Newton 403 HydroBond to provide a complete waterproof envelope to the structure, forming a Type A (barrier) waterproofing solution suitable for Grades 1, 2 and 3 as defined by BS 8102: 2009.

Surface preparation is required, as is protection after application - consult manufacturer for details.

Features and benefits:

  • Accepted by the NHBC as a suitable waterproofing system for Type A waterproofing to grades 1, 2 and 3 - BS 8102: 2009.
  • Fully-bonded seamless membrane.
  • Very flexible, easily dealing with movement and settlement.
  • Cost effective.
  • No shrinkage.
  • Can be applied in cooler and damper conditions, and without a primer.
  • Very quick to apply – 1000 m² per day (maximum).
  • Solvent free, non-toxic and odourless.
  • Non-flammable and no volatile organic compounds (VOCs).
  • Chemically resistant.
  • Suitable substrates include concrete of at least 20 kN, concrete block walls with flush pointing, screed, and insulated formwork walls (ICF).
  • CE marked, and manufactured in accordance with EN 15814: 2011+A2: 2014.
  • Where the membrane is exposed to UV and weathering, the life expectancy is 10 years.


  • Waterproofing and radon protection of basement walls as part of the Newton HydroBond System.
  • Standalone waterproofing membrane for basement, foundation and earth-retained walls.

Suitable surfaces:

  • Walls (positive pressure).
  • Covered and loaded decks (positive pressure).

Can only be sprayed with a specialist spray machine - consult manufacturer for details.
