Quick question, we have crazing paving in our back garden /yard.. we are pulling this up and putting down slate pieces in place of this. Now i know we need some kind of protection under the slate from the soil. Is Garden Membrane the thing i need to use. (as you can probably tell im not very green fingered)
Robinia speaks the truth! I put down a lot of what turned out to be a cheap product, in my own garden. Lots of lovely weeds now :o(
If you have a good enough slope, I just use heavy duty polythene membrane (used under house floors.) The gradient means that water can't build up or "pond" on the surface.
