Why slabs sink and rise here
On the expansive clay of Northeast Tarrant County, slabs don't only sink; they can also rise. After a wet season, swelling clay can push a walkway panel up at one end; after a long dry summer, shrinking clay leaves voids under slab edges and lets sections drop.
Sinking is especially common next to the house, where backfill against the foundation was placed loosely when the home was built and roof water lands on the same spot year after year. Driveway panels at the garage, porches and walkways along the foundation are frequent candidates for leveling.
Leveling works on the sinking side of that problem. If a slab has dropped and is still in one or a few large pieces, it can usually be lifted back to level and the space beneath it filled.

How lifting is done
Small holes are drilled through the slab in a planned pattern. With polyurethane foam, a two-part material is injected that expands to fill voids and gently raises the slab; it's light, cures quickly and adds very little weight to the soil. With slabjacking, a cement-based slurry is pumped through slightly larger holes to fill voids and lift the slab.
The lift is done slowly while someone watches the slab against a string line or level, so it comes up evenly without cracking. Once it's in place, the holes are patched and the joints along the lifted area are sealed.
Most residential leveling jobs take a few hours. With foam, the slab can usually be used the same day.

When leveling isn't the answer
Leveling is for flatwork: walkways, driveways, patios, porches and pool decks. It isn't a substitute for foundation repair, which deals with the house itself and uses different methods.
Slabs that are badly broken into small pieces, crumbling at the surface or very thin are usually better replaced. Panels that have been pushed up by swelling clay or tree roots can't be lowered by injection; they may need grinding, cutting or replacement.
A good contractor will tell you when replacement is the smarter choice, and explain why.

The gap at the garage
One of the most common leveling jobs in the Mid-Cities is the driveway panel nearest the garage. As fill against the foundation settles and roof water soaks the area, that panel drops and leaves a step down from the garage floor, often with a gap where water runs under the slab.
Lifting the panel back to the garage floor and sealing the joint closes that path for water. Moving the nearest downspout away from the driveway, or connecting it to a buried line, keeps the panel from dropping again.

Fixing the cause
Lifting fills the void, but the slab will sink again if the cause stays. The most common causes are roof water landing beside the slab, open joints that let rain run underneath and uneven watering that keeps one side of the slab wetter than the other.
North Richland Hills limits outdoor watering to twice a week year-round. On watering days, sprinklers that soak the edge of a driveway or walk create exactly the uneven moisture that clay reacts to, so adjusting spray patterns is worthwhile.
Redirecting downspouts, resealing joints after the lift and keeping sprinkler spray off the slab edges help leveled concrete stay level.

Trip hazards and safety
A raised or sunken edge of even half an inch on a front walk is enough to trip someone. For homes with young children, older relatives or frequent visitors, leveling those edges is one of the most useful small projects there is.
Pool decks that have settled away from the coping can open a gap that lets water flow under the deck, making the settling worse. Lifting the deck and resealing the joint is usually enough to stop it.
Acting early is cheaper. Small voids take less material, and a slab that hasn't cracked yet can be lifted in one piece.
Businesses, churches and rental properties with walkways used by the public often level trip edges as part of regular maintenance, since a small fix now is far easier than dealing with a fall later.

What it costs
Leveling prices depend on the area to lift and the amount of material needed to fill voids, which is only fully known once the slab is drilled. A fair estimate explains how extra material is charged.
Questions
Concrete Leveling — asked and answered
Can a slab that rose be lowered?
Not by injection. Raised panels may need grinding at the edge or replacement.
Is foam or slurry better?
Foam is lighter and faster; slurry is heavier and often economical for large voids. The slab and soil decide.
Will the holes be visible?
Yes, as small patched circles, more noticeable on colored concrete.
How long will it last?
As long as the soil underneath stays stable. Managing water around the slab is key.
