Our patio has settled into a negative slope toward the house. When it rains,
the patio floods like crazy. The patio is 32' x 25', and I'm trying to avoid
ripping it up to correct the issue.
There's really nowhere for the water to go left or right. I only have the
option of pushing it straight away (rather than toward) the foundation,
because it is that way that a drainage easement lies to catch the water by
piping it toward it.
Is there a way that I can reslope concrete to re-pitch it, or another way to
get rid of the water by some type of drainage method other than installing
an outdoor sump pump?
