Flagstone Patio pitched slightly towards house and water collects

[massimofinance]

Is my only option to rip it all out and re-lay it? It’s in cement. I bought a pool cover water pump but it doesn’t turn on until there’s an inch Or more of water. Any other ideas? Thanks.

There is people out there that can raise the slab by pumping foam under it. Look it up on the net and see if there is one in your area. Here is one example.

only way to re-pitch without tearing out and re-doing is to water-jet some dirt out from under one end and jack up the other with either mud jacking, foam jacking or concrete jacking

I have to re-pitch the whole pool/lanai area as the slab settled about one inch over the past 20 years and the pool deck doesnt drain right....... and those are the only options I have come up with for my issue.

Can you saw-cut the slabs near the house, dig it out and drop in a zipper drain?
