4m x 50m Polythene Builders film is typically used under concrete as a moisture barrier and is our most popular size of poly. The 200micron film is folded in half before being rolled onto the roll. This greatly reduces the length of the roll making it easy to carry and transport.
Builders film also has a wide range of general construction uses such as membrane protection, floor protection, material containment, asbestos removal, pond lining, temporary roofing, etc.
