Any cladding material is only as good as the substrate supporting it from below. Your concrete is failing. Maybe the soil under it is subsiding due to site grading issues creating erosion. Maybe the soil under it wasn’t compacted properly.

Concrete subsides because of what is below it. Just as stone would fail because of the failing concrete below it. It’s a chain. That subsidence must be repaired. Period. No it won’t be a cheap fix. It has to happen.

The compacted soil that holds the concrete up also supports the pool sides. If you let it go on too long, the structural integrity of the pool can be affected and it will cost even more to fix them.

Thank you. It’s definately a specific area between the pool and house where one side is now sloping towards the house and the other is raised causing the tripping hazard.

Can’t jacking up the slab be an option? If I break up the concrete and resurface I’d probably have to replace the entire area which is quite large. If I only replace that section then it will look different from the rest of the area.

What did you end up doing? We are having that same problem.
