Hi,
I'm building a small retaining wall, only 6 rows tall, double skin. I have already done first 5 rows so I am now at the point where damp-proofing should be done.
I have bought a membrane, 1200 gauge, for the external (earth) side of the wall, but I am bit puzzled with how to lay it - since earth will be up to top of the 5-th row only I thought I could start laying it from between two topmost rows (so it's squeezed underneath the topmost row), but I can't find any images or examples that it's the correct way. Does this make any sense?
Another thing is what to use as a protection board, between the membrane and earth? For example I found some sold by "RIW", but they seem to be specialised for industry, not DIY-ers, so I need something that is easier to get.
Any advice much will be much appreciated!
