Newtonite Lath Mesh Membrane

Damp proof membrane, comprising of high density polyethylene membrane with a rot-proof polythene mesh that is heat-welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.

    Key Benefits

    • Provides a surface that is totally separated and unaffected by the dampness within the wall ensuring that the wall finish will never be affected by moisture or salts.
    • Superb ‘key’ for renders or plasters.
    • No need to use injected damp-proof courses which unnecessarily pump chemicals into the property.
    • Quick and easy to install.
    • In many cases, the existing render can be left on the wall.
    • No requirement for damaging preparation to the wall surface.

    Typical Applications

    Typical Applications

    • As a damp-proof base for renders, plasters or dot & dab plasterboard.
    • As a damp-proofing system to deal with rising damp.

    Newtonite Lath Mesh Membrane is light, clean and easy to handle. It can be cut with a sharp knife, scissors or shears. The membrane is inert and is highly resistant to water, alkalies, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.

    Newtonite Lath Mesh Membrane is guaranteed against deterioration for 30 years and has a life expectancy of at least 50 years.

    Newton Waterproofing Systems was formed in 1848 and, as the first British company to produce a meshed membrane, we are now recognised as the leading supplier of damp proofing membranes in the UK. Newtonite Lath Mesh Membrane can be purchased directly from Newton or from leading builders merchants.
