Capital Valley Plastics Ltd Damp-Proof Membrane Black 1000ga 4 x 3m is rated 4.1 out of 5 by 7.
Rated 5 out of 5 by from Suppressing weeds and uneven ground Bought two of these recently to completely cover a fairly large area of weedy back garden beside a new allotment. Planning to leave it there long term to suppress nasty bindweed and other weeds. Seems very durable to all weathers. Being held down by large rocks. Would definitely recommend.

Rated 5 out of 5 by from Not bad for the money Originaly bought this to use under a workshop as a membrane. It worked well and I ended up buying more of the 1200ga to line the walls and rood before feather edging and felting. The 1000ga membrane is quite flexible and easy to move into place. It also folds well. The 1200ga is a better buy though as it feels a lot more durable.

Rated 5 out of 5 by from Does the Job at a great price As others have said, my sheet was folded on arrival, but it unfolded without any holes and goes down without trouble. Tough enough to survive being lugged across a building site, laid down and walked all over before building started properly. The sizing is accurate, with maybe a little bit extra in my favour.

Rated 1 out of 5 by from Lots of holes Two out of the three that I bought had holes in. Big enough to get a pencil through. Not good when you're buying an impermeable layer really.
