Can I use Newton damp proofing membranes in a below ground (earth retaining situation)?
A. No. Newlath 2000 is suitable for dealing with all forms of damp conditions above the ground but the fixing plugs do not deal with the potential of running water, and the system has only been independently tested by the BBA for damp-proofing. For retaining structures use Newton System 500 with suitable drainage.
