Sinking Patio Repair in Central Illinois

With patios, the big thing I would watch is where the water is going. A patio that settled away from the house is one kind of problem. A patio that now sends water toward the house is a bigger conversation.

Furniture wobble, a gap at the foundation, a low corner, or a toe-catching edge can all point to settlement. If the slab is still mostly intact, patio leveling, mudjacking or foam lifting, and drainage should be compared.

If the patio is cracked apart or the surface is failing, use the replacement guide before spending money on a lift.

Patios depend on the base underneath staying put. Water can wash out soil, downspouts can dump too close, and poor compaction can show up years later.

Freeze-thaw movement, age, and ordinary soil or base movement can make a patio tilt or drop. Sometimes it is not dramatic. It is just water plus time plus a slab that lost support underneath.

I would ask about patio leveling when the slab is mostly intact, the main issue is settlement, and the patio still looks usable. A low corner, a bad slope, or water pooling because the slab dropped can all be worth checking.

A contractor still needs to see it in person. The question is whether lifting can support the slab and improve the slope without pretending bad concrete is new concrete.

Replacement may be worth pricing when the patio is badly cracked, crumbling, too thin, root-heaved, broken into several pieces, or sitting over severe drainage and base problems.

If it just settled, lifting may be worth a look. If it is falling apart, that is a different conversation.

A crooked patio is annoying. Water running toward the house is more than annoying. That does not mean panic, but it does mean the slope and drainage should be part of the conversation.

This is where people get tripped up: lifting the slab may help if settlement caused the slope, but downspouts, grading, or washout may still need attention.
