Newton 503 Mesh Cavity Drain Membrane for Basements

3mm Cavity Drain Membrane for Basement Walls, Floors and Vaulted Soffits

Newton 503 Mesh is a BBA certified meshed membrane suitable for use as a waterproofing membrane when used below the ground as part of Newton System 500.

With its 3mm stud, Newton 503 Mesh is just 3.5mm in overall thickness, and is the preferred meshed membrane where space is of a premium. Its high quality meshed surface provides an excellent ’key’ for lime mortars, renders, plasters or dabbed plasterboard. When using our Newton 503 Mesh it is essential to use Newton MultiPlug or Newton NuSeal with WaterSeal Rope as a means of achieving a waterproof seal.

Newton 503 Mesh is supplied in roll sizes 1m x 20m achieving 20m² (M11) and 2mx 20m achieving 40m² (M12)
