Newton 520 eco is a cavity drain waterproofing membrane made from recycled High Density
Polyethylene (HDPE). It is one of the main constituent parts of Newton System 500, our
BBA Certified, Type C cavity drain system, used for waterproofing of floors within earthretained
structures, that includes drainage channels sited below the membrane for increased
drainage capacity. With its 20 mm deep stud profile, Newton 520 eco is used within Newton
System 500 as a high drainage capacity floor membrane and is generally specified where it
is anticipated that there may be a risk of severe water penetration.
