It does it's job, used for under floor insulation and screed. it could be manufactured better, as it is full of creases, in which some can not be smoothed out, but this is characteristic across all DPM's of this weight, a shame though.

Fulfilling expectations

When I opened the roll a huge area was nearly transparent and in fact I accidently put my thumb through it at one point. Unfortunately it was going under concrete and had to be used that day, however I did cut the thin area out as it was unusable.

Excellent for the allotment.

Way strong enough for a dpm; I use it as a tarpaulin where it's just as good, and does not easily tear.

Decent DPM

Decent dpm. Used for covering broken windows on-site. I needed something reasonably strong but could let a bit of light in

An easy lay.

Wouldn't waste my time buying this, it was full of holes over an inch in size which had to be taped over, poor quality.

Used to cover an ongoing project of upgrading my drive as a barrier to park on, to stop mud sticking to my car tyres and being sprayed all over our shared drive.

DPM with holes

. This is advertised as a DPM, when rolled out for first slab there were two large holes about the size of a £2 coin!
I had read the reviews, but I thought they must have fixed this problem, they haven’t!!!
