Learn more about Newton Waterproofing

Newton Waterproofing is a long established independent supplier of basement waterproofing and damp proofing products. Established in London in 1848, they are well known for their very high quality waterproofing and damp proofing products. 

Back in 1931, John Newton introduced the Newtonite lath membrane to the UK. It featured corrugations to create an air gap between the wall and the Newtonite membrane, allowing the wall to breathe. In 1984, the current chairman Christopher Newton invented Newlath – HDPE dimpled sheet membrane with heat welded nylon mesh.

Newton's membranes have more recently been used in buildings including Windsor Castle, London Underground Station, Houses of Parliament and the Royal Courts of Justice.
