Rain runoff
Water around the patio edge can expose or worsen a support problem, especially where the yard or roof drainage concentrates flow.
Patio slabs
Uneven patio slabs in Toledo?
When a patio sinks or tilts, the surface can feel awkward underfoot, collect standing water, or start sending runoff toward the house. The useful question is not only whether the slab can be lifted, but whether the finished slope and any active water source are being considered at the same time.
A repair conversation should separate the slab's current position from the drainage conditions around it.
Why patios settle
Uneven patio slabs
Attached structures
Patios that meet stoops, steps, or foundation walls can settle differently from the structures beside them.
Repeated freeze-thaw
Seasonal movement can make existing shifts, cracks, and drainage changes easier to notice.
Ground support
If the material under the slab no longer supports it evenly, the patio may sink in one corner or along one edge.
Helpful questions
Concrete patio leveling vs replacement
Is the patio still usable?
Leveling is usually discussed when the concrete is still serviceable enough to lift and settlement is the main problem.
Is water creating a second problem?
If runoff still reaches the same low edge, include that active water source in the repair plan instead of assuming a lift alone solves it.
What should the finished slope do?
If the patio now pitches toward the house, ask how the proposed repair changes drainage direction after the slab is lifted.
Drainage and leveling
Related problems, but not automatically the same repair
Intact slab, no obvious active runoff
If the concrete is mostly intact and the settlement appears localized, leveling may be worth evaluating.
Patio now slopes toward the house
Restoring useful slab geometry may be part of correcting where surface water flows.
Water keeps arriving at the same edge
A downspout, low yard, or recurring ponding condition deserves attention alongside the slab height.
Before you call
Photograph the slab and the water path
Take a wide photo from the house looking across the patio, a close photo of the settled edge, and another showing nearby downspouts, low yard areas, steps, or adjoining slabs. Photos after rain can help show whether the visible settlement and the water path are related or separate questions.
