Clay slab leveling
Sunken driveway slab in Clay? Do not allow a pour on frozen ground
A slab at your Clay house has sunk and you want it raised or replaced. Ask when the work will happen, because concrete placed on frozen ground fails as the ground thaws.
A Clay slab lift you book here brings $100 off your first job, applied when you book.

What puts slab leveling work on your list in Clay
A slab lower than its neighbor
A drop between panels breaks the edge, catches wheels and holds water against the concrete.
Water running toward the garage
A tilt that sends meltwater to the door is a bigger risk than the crack.
A hollow ring when you tap it
Hollow-sounding concrete suggests soil has washed away below.
Settling beside a downspout
A slab by a downspout may sink because water keeps getting under it.
Questions
Slab leveling questions from Clay homeowners
- 1
Can a sunken slab in Clay be fixed in winter?
Placing concrete on a frozen subgrade is poor practice. Ask the contractor how they will clear snow and ice and check the ground, or whether to wait until it thaws.
- 2
Why do slabs sink near downspouts?
Water running under a slab can wash out or soften the soil. Ask the contractor where your downspouts discharge and how drainage will be fixed along with the lift.
- 3
Is a lifted slab as good as a new one?
Only if the concrete is sound and the cause is fixed. A slab with widespread scaling or cracking may not be worth lifting. Ask for both options in writing.

Winter replacement needs bare, unfrozen ground
Snow, ice and frozen ground must be cleared before concrete goes down. Frozen ground thaws unevenly, and a new slab on top of it settles. If your slab is replaced in winter, ask how the contractor will thaw and check the base.
Book first, then the $100 comes off.
Ask also whether the work should wait. A slab that is only a trip hazard may be safer to mark and leave until spring than to pour on a bad base. The contractor should be able to say why they choose either one.
If the contractor does lift the slab, ask them to check the lifted height against the door threshold and the walk so you are not trading one trip edge for another.
Frost heave adds to the trouble. It needs freezing, a water supply and soil that holds water, so drainage is the lever you can pull. Ask what the contractor will do to move water away from this slab.

Why a Clay slab sinks and what to ask
Clay's median house dates from 1978, so many slabs here have sat on the same ground for decades. Soil can compact, wash out or shift near downspouts and cracks. Ask the contractor where water goes and what is under the slab before they suggest a method.
Tell them when you first noticed the drop, whether it has changed and whether it affects a walk, a patio or the drive. Ask whether lifting will address the cause or only the symptom.
Want the paperwork checklist?
Check gutters and downspouts too. A downspout that empties beside the slab can wash soil from under it again, however well the lift is done.
Mark the low corner with chalk and take a photo each season, so you can show whether the slab is still moving when a contractor visits.

A slab that meets the road is a different job
If the sunken piece is the apron at the road, it sits in the right of way. Clay has town, county and state roads, and your road owner decides the permit. Check the town's driveway permit form and ask the Highway Department which road you front.
Keep the interior slab and the road edge as separate lines in the contract, so each can follow its own approval.
Ask which parts are the contractor's to arrange and which need the road owner. Note who you talked to at the office, and the date.
