The Laydex 1200 Gauge Builders Film - Black is an un-reinforced LDPE polythene membrane for use under concrete floors. This quality black membrane is CE approved, and safe and clean to use. It will help prevent rising damp and property damage. This Laydex film conforms to building regulations. Black polythene deteriorates at a much slower rate than clear polythene when exposed to UV light, so this film is a longer lasting alternative. This roll is 3.5m multi-fold.
