Damp Proof Membrane 300mu Black 4m x 25m is rated 4.4 out of 5 by 17.
Rated 5 out of 5 by from Perfect for any job without leakage worries Bought before from Toolstation. Endless uses and in addition to its main purpose is particularly good as roofing material as it lasts far longer than other materials and panels. As example just demolished 2 x 20 year old sheds which had nothing but this damp proof membrane over the ceiling boards. It has suffered severe freezing winter temperstures, gales, heat from the sun but has remained intact and fully water secure leaving the sheds perfectly dry inside. Too good to throw away after being removed and so still in use for other things. Its my first choice for keeping water out.

Rated 5 out of 5 by from Sturdy and tough Had this before and does not fail to satisfy. Great as temporary cover for goods on site and then can be re-used as a membrane with no fear of tears or splits.

Rated 2 out of 5 by from Poor delivery Order online for next day delivery before 10.00 am on a Friday morning and received an email confirming it was ready for dispatch virtually straight away, actually phoned to ensure it would be sent overnight to the selected store and was told that it was in stock and there was no reason why it shouldn't be delivered on Saturday. Still awaiting a phone call on Monday to say its in the store. Checked the parcel tracker and it shows its been delivered 10.43 am to the store this morning. Not happy when i needed it for the weekend,
