Root barrier

[mylesw]

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, would probably not make much difference?

Any advice appreciated.

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

It might divert the roots if the membrane is solid but it will break through if there are even small holes. Roots of a neighbour's firestorm shrub have broken through the pot and the concrete path underneath where there is a small crack. Water draining from your shed roof to the surrounding ground will also attract the roots of the pleached trees.
