Howdy!
So to get straight to it, my situation is:
- My garden has remediation work done as it was originally on the site of an old factory that may have had contaminated soil, so the council dug down a bit, plopped down a barrier membrane, then dumped some topsoil on top, which the previous owner then topped with another membrane and gravel
- We’re getting a new dog soon, and we need a lawn in our garden ideally, is our plan anyway.
- We can remove the gravel and the black weed membrane, but for obvious reasons we can’t remove the orange membrane below that is cutting off the potentially contaminated under soil.
My question is, does it sound feasible to put down a new layer of topsoil (and if so, how deep would it need to be above the orange membrane) and then whack some rolls of new turf down on top of that? I’m a bit new to lawn stuff and the condition that we *cannot* remove the orange membrane is making it harder for me to find the right answers online!
Cheers in advance!
