Hi, thanks for the replies.
It doesnt get much use no. The garage sits on one corner of the property, and the path runs down one side of the garage, and around the back of the garage. The path down the side of the garage is level with the adjacent neighbours garden. But, at the back, our garden is about two feet higher than the adjacent property. (They built our street first, and its higher than the street behind)
The path at the back of garage, looks like it is basically a two feet high wall made of stone and bricks with concrete and flags on top of it. Its not loose or wobbling but its sloping away, from the garage wall hence the gap. Those broken flags which look like they are propping it up, are mainly cosmetic i think, but they may have some structural purpose. Because the neighbour at the backs garden is lower, it might be slipping?
The other side of the fence is the neighbours lawn, which is about two feet lower than the surface of the path.
Theres no way i can prop it up, push it back towards the garage wall, pin it somehow then? do I need to have the entire path broken up, removed/remade, is it going to get worse, unless i do something about it? Does it need to be fixed to the garage wall?
I shouldnt just get someone to pour some concrete in the gap to fill it up and leave it at that?
What kind of tradesman do i need, or will a good odd jab man be able to do it?
Cheers
