HydroBond 109-LM

  1. Cold-Applied Resilience: HydroBond 109-LM, a flexible single-component rubber membrane, offers seamless and cold-applied waterproofing. Ideal for external use on earth-retaining structures like basements, it ensures puncture resistance, boasting an impressive 850% elasticity and 95% recovery memory.
  2. Engaged Waterproofing: With outstanding puncture resistance, HydroBond 109-LM fully engages with the substrate, preventing water tracking. Suited for all below-ground structures, from domestic basements to large civil engineering projects, it’s a reliable solution for comprehensive waterproofing.
  3. Certified Reliability: HydroBond 109-LM is a key component of the Newton HydroBond® System, backed by BDA Agrément Certificate BAB 16-031/04/A. Recognized by NHBC, it meets the standards for Type A Waterproofing to Grades 1a, 1b, 2 & 3 – BS 8102:2022, ensuring a reliable waterproofing system.

Flexible, single-component, cold-applied and seamless rubber waterproofing membrane used primarily for the external waterproofing of earth-retaining structures such as basements and foundation walls.

HydroBond 109-LM is extremely puncture resistant with elasticity of 850% and a 95% recovery memory. The membrane becomes fully engaged into the substrate 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.

HydroBond 109-LM is also a constituent product of the Newton HydroBond® System supported by BDA Agrément Certificate BAB 16-031/04/A and is accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1a, 1b, 2 & 3 – BS 8102:2022.
