Newton Waterproofing System’s BBA Approved damp proof membranes are made from High Density Polyethylene and Polypropylene which means that they are impervious to moisture and have a high resistance to water vapour transmission. They also provide an effective barrier to the transmission of salts or other contaminants. The surface of the membranes is shaped into a stud formation – this ‘egg box’ profile is a major advantage when treating damp as it allows moisture to evaporate from the wall unhindered so that there is no danger of the dampness being guided elsewhere. This type of membrane also has a high resistance to puncture and will not be damaged by normal foot traffic during installation, or while laying concrete, or screeding. It can support the long-term loadings likely to be experienced in service without undue deformation.
