Polythene Damp Proof Membrane 500mu 4m x 12.5m

The Polythene Damp Proof Membrane 500mu 4m x 12.5m is a heavy-duty construction membrane made from robust polyethylene sheeting designed to provide effective moisture and damp protection in building projects. At 500 micron (2000 gauge) thickness, this polythene damp proof membrane delivers a strong, watertight barrier suitable for use beneath concrete floors, slabs, foundations and internal ground floor build-ups. The 4 metre by 12.5 metre roll offers approximately 50 m² of coverage and is flexible for ease of handling and installation on site. This durable damp proof membrane helps prevent rising damp and water ingress to maintain structural integrity and compliance with standard UK damp-proofing practices.
