Newton 109-LM

Seamless Rubber Waterproofing Membrane

Newton 109-LM is a flexible, single-component, cold-applied, seamless rubber waterproofing membrane with a number of uses for the external waterproofing of basements, foundation walls, decks, and flat roofs. Newton 109-LM is also used as a detailing membrane for the termination and jointing of other Newton waterproofing products, and with its very high adhesive properties, it is the perfect primer for the adhesion of butyl products to concrete and mortar.

  • Key Benefits

    Fully-bonded seamless membrane

    Very flexible, (850% elasticity with 95% memory) easily dealing with movement and settlement

    Primer not required for most substrate

    Complete vapour barrier

    Can be used as an adhesive for insulation to decks

    Solvent free, non-toxic and odourless

    Non-flammable – No VOCs

    Multi-use product: waterproofing, detailing, priming and repair

    Can be used over damp substrate

    Excellent adhesion to all clean and prepared substrate

    Compressive load capabilities to allow seamless termination from below ground to DPC

    Waterproofing membrane to decks, balconies and flat roofs where the membrane is to be protected by covering over, such as green roofs, timber decks, paving, etc

    Waterproofing of retained structures, together with Newton 403 HydroBond

    Typical Applications

    It is adept as a detailing membrane for the termination and jointing of other Newton waterproofing products, and with its very high adhesive properties it is the perfect primer for adhesion of butyl products to concrete and mortar.

    Applied by brush, roller or airless spray machine, Newton 109-LM can be applied in cool and damp conditions and without a primer.

    Newton 109-LM is extremely puncture resistant with elasticity of 850% 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 109-LM can be used in isolation or in conjunction with other Newton waterproofing and damp proofing products to provide a coordinated and combined approach to the waterproofing of the whole structure that includes protection against water ingress to the deck, through construction joints, through and around service entries and to movement joints.

    Correctly protected, Newton 109-LM will provide, under normal service conditions, a durable waterproof covering for the life of the building to which it is installed; the expected lifetime of the building itself should be at least 60 years. The Newton HydroBond System is supported by BDA Agrément Certificate BAB 14-031/02/A for structural waterproofing and by BDA Agrément Certificate BAR 14-034/01/A for Newton System RubberFlex for decks and flat roofs.
