    Newton 803 Newtonite 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.

    Newton 803 Newtonite is guaranteed against deterioration for 30 years, has a life expectancy of at least 50 years and is supported by BBA Certification Certificate Number 94/3010.

    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. 803 Newtonite can be purchased directly from Newton or from leading builders merchants.
