Just moved into a 103 year old Georgian house with a large ish garden. Whilst the lovely lawn is beautiful we can’t do very much with the slabbed areas as we plan to do an extension in five years or so. But there is a seating area in a nice shady corner that we could do but loathe to spend money getting trades in to do up as spending a bit now on kitchen etc. can someone say if these slabs b be remedied or rescued in anyway without digging it all up and slabbing anew?
