Hi
We have a reform property, (old stone walls etc). The upper floors need reinforcing. We are aware the local solution to this is to put rebar in the exterior walls and bar mesh on top then pour lightweight concrete on top.
My questions are:
How big is the structural rebar in diameter and what spacing should be used between them.
How thick should the concrete be
Should an expansiion joint be placed between the new floor and the exterior walls
Can the original floor be removed after the newly poured floor is set
Would be greatful is anybody could help with this
