I have a smallish (2m x 1.5m) section of my barn that is very uneven cobbles (see pic). It has no aesthetic merit and probably little historical value other than being maybe 250 years old. I need to be able to manouevre pallet trucks over this area, which is very difficult, so I would like to make it a bit smoother and flatter. The obvious answer is just to pour concrete over it - much of the rest of the barn was concreted some time ago and I don't know what is underneath. However, I'm reluctant to do anything that is not reversible. Does anyone have any better suggestions?
Thanks.

Thanks.
