A brick patio floor has sunk and pulled away from the adjacent wooden mud-sill. It has subsided about 1/2″ and is a hazard that is going to get worse.
I’ve heard of a system or method of correcting the problem by injecting foam through small holes drilled into the rubble filled space under the brick, but can’t find out anything more about it.
Anyone have some help for me?
Thanks a lot.

Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.

Is it dry fit or cemented in? What is the substrate, sand or a concrete pad? Personally, my thought is that it is sinking because of time and compacting and water. I would need more information to answer your question.

Ther are some people out there who "jack concrete slabs" by injecting grout under them, but on brick I don't know. I would need to know how build, whats under the brick . Maybe cheaper to redo the whole thing
