Rated 1 out of 5 by Poor quality control Bought this DPM and placed it in the forms of a garage base before a concrete pour. just as the concrete truck was arriving I noticed that there were holes in the membrane. The holes appeared to be from poor manufacture process that had melted or badly formed the sheeting. The holes were quite small around the size of a pea but on closer inspection the surrounding material was paper thin. We quickly patched the holes and proceeded with the pour. Very unhappy to be patching a DPM. On reading other reviews I am not alone with this problem.this product should be pulled from the shelves as it is not fit for purpose. If you do buy this DPM play close attention to the middle sections and look for patches that are not quite the same colour or texture, not easy if it is chucking it down! Poor show from Screwfix obviously they do not realize that this product has to be perfect as digging up a concrete base hunting for a water ingress point is not a scenario anyone wants to encounter. 24 Jan 2016
Rated 1 out of 5 by Poor quality DPM I collected this from my local branch and on inspection it had obviously been dragged along the floor at some point, which meant it was peppered with holes. It is also a lot thinner than 1200g membrane I ended up buying from my local builders merchants, which is of concern as it was to be used under a concrete floor to regs. Be careful with this product. 7 Oct 2015
Rated 1 out of 5 by Disappointing I used this product as damp proof under a concrete floor. Unfortunately on spreading it out, the day before my concrete arrived, having cut the roll to length, I found a number of holes in it. They were around the size of a five pence piece, and appeared to be a manufacturing fault. It was too late for me to change rolls, so involved lots of patching, expensive bonding tape and time. Would not recommend this product for the job it is designed for.. 12 Sep 2015
Rated 2 out of 5 by good but holey lucky I bought 50m, but only needed 20m, as I had to put 2 layers of it down, as 3 separate random holes were in the role, they looks like something has melted it. so beware and order plenty. 31 Jul 2015
