Newton 805 Newlath is a composite damp proofing membrane comprising of high density polypropylene membrane with a rot-proof polythene mesh 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.

The membrane is inert and is highly resistant to water, alkalis, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and there small organisms.
