Rated 5 out of 5 by Piece of cake This underlay made laying a boen oiled oak floor a breeze. It's a bit more expensive but it's a great quality product and actually per meter a very good price. Do not hesitate. Only reason not to give reliability a 5 star is we only laid at the weekend! So to early to really say 10 Jun 2014
Rated 4 out of 5 by Worth every penny Fantastic underlay. Strong & durable. Take time to put it down & your floor will simply fall into place. 21 Jun 2013

I would like to use this on the cellar floor before I lay the concrete on top. I would also like to use the product on the cellar walls for damp proofing and then plaster boarding with glue
I will attach the membrane using damp proof wall plugs and then glue the plasterboards on top.
