Rated 5 out of 5 by from Spot on I purchased this to use inside a small metal shed that I had previously put a layer of concrete down as the base but over time the moisture began to seep through so decided to do another layer but 1st I would PVA the initial layer then place this plastic membrane sheeting down and cover with the 2nd .. This sheet was plenty in size and and a good thickness and good quality so I'm hoping when the winter months are here it will stop the moisture rising through the floor and creating a dew point on the ceiling and causing havoc and puddles inside this will be teamed up with some form of polystyrene insulation glued to the inside of the roof .. I'll keep people updated on how this works as this is a common problem I metal sheds . Cheers
