I purchased these in January for a shed build i havent got around to doing. Everything you need to know is in the photos. They simply click onto base bearers to act as another damp barrier preventing water ingress. There is 102 pieces. 70 brand new in box Local collection / pick up only. Do not bid if you cannot collect from Birmingham. I paid £300+ for it all (see invoice for 70 pieces which was £252 itself £200 all in is an absolute bargain
