Root barrier membrane

Hi.
I am in the process of planting some pleached trees behind my shed… unfortunately the neighbour at the rear has chopped a large tree down in her garden and now we both overlook each other.

I’m really limited for space in terms of where to plant. I’ve basically got 50cm gap to try to squeeze something in.

I’m slightly concerned about the roots disrupting my shed base ( which is type 1 mot, cement then council slabs). I only put the shed in last year (before she chopped the tree down) so don’t want to have to move it.

So I decided on 2 pleached trees to go behind the shed which are being delivered at the end of this week.

My question is - would a root barrier (membrane) offer any/sufficient protection against the root’s disrupting the shed base? Or am I overthinking it / or even if I did install one, might it be ineffective in any event?

Any advice appreciated.

I’ve attached a couple of pictures so you get the idea.
Cheers

 

I think some research maybe regarding tree types could be in order.
Some trees are known to be surface rooter that put out long large woody roots very close to the surface.

Others tend not to do that and are less of a problem.
Maybe ask the supplier for some info.
I don't think you would hold a determined tree back with a root barrier.

 

Would you be able to empty the shed, lift the shed on to a roller(galv water pipe) and move it forward so that you could more easily dig deeply to accomodate the root ball thereby getting maximum support to prevent the tree(s) rocking and disturbing the base. Growing large trees will likely cause lifting by expansion of the root, inevitable in such circumstances

 

Agree with infradig, not enough room there for a tree. The top growth as well of the roots could be a problem. Unless you keep the top well pruned it will grow against the rear of the shed and maybe damage the walls
