Description
Polythene Building Film – 4m x 50m
This heavy-duty Polythene Building Film acts as a critical vapour barrier and waterproof membrane for concrete construction. Its 200-micron (or equivalent) thickness provides a robust, puncture-resistant layer that prevents ground moisture from rising into concrete slabs and footings. The 4m width and 50m roll length offer efficient coverage for residential and commercial slabs, helping to control dampness, reduce cracking, and protect steel reinforcement from corrosion.
