Hi, I'd appreciate some advice on this. I have a 4ft deep crawl space under my floor. The solum is slightly damp earth so I've been advised to damp proof it to prevent damp and smells rising up.I'm laying thick polythene and weighing it down with a few inches of gravel.I need about 5 bulk bags.I'm assuming the gravel will be wet so I'm wondering, will I actually be creating a problem with damp rather than preventing one?
Many thanks, Jonny.
