Planning to cut open a 36"x36" hole in my concrete slab to repair an
underground PVC sewer line. I have no idea if the repair is to be just at
the break, or I need to replace a longer section that may be pitched back
due to the break. I will be hiring a plumber to come do the repair.
For the concrete cutting I will be hiring another company to come do it. I
assume when I cut through the slab there will be either wire mesh or rebars,
when I finished the plumbing repair, I will need to redo the mesh right?
Will the concrete saw make a clean cut? If so how do I tie back another
mesh? Do I need to drill holes in the slab "sideways" to expose the mesh or
If I do not replace the mesh, I think the weight of the concrete slab will
eventually settle on the PVC pipe and that's bad.
One more thing, I understand when they install PVC pipe to ensure proper
slope they install "hangers". How can hangers be installed when you are
doing it from above and the concrete slab is not even poured?
