Crack repairs are published at $100 to $400 nationally and larger repairs at $600 to $3,000. Desert concrete does not suffer frost damage, so most repair calls in Scottsdale come down to three things: water getting under a slab, soil that swells or collapses, and decades of sun on an unsealed surface.

Can cracked concrete be repaired or does it have to be replaced?
It can be repaired when both sides of the crack sit at the same height and the slab does not move underfoot. Those cracks are cleaned out and filled with a flexible sealant so monsoon water stays out of the base. Replacement is the answer when one side has dropped, when the slab is in several loose pieces, or when cracks keep widening from one summer to the next.
Why is my concrete driveway cracking?
Most driveway cracks here start with movement in the ground or with heat. Concrete shrinks as it dries, and in our dry air it dries fast, so a slab with too few joints cracks where it chooses. Later cracks usually trace to water: irrigation or a downspout soaking one edge so the soil swells or washes out. Heavy vehicles on a thin slab and roots from thirsty trees do the rest.
Why is my concrete sinking, and can it be leveled?
A slab sinks when the soil under it loses volume or washes away. Around Scottsdale the usual causes are fill that was never compacted along the house or over a utility trench, desert soil that collapses the first time it gets soaked, and a leaking irrigation or pool line. If the slab is still in one sound piece it can usually be lifted back. The water source has to be found and fixed first, or it will drop again.
How much does concrete leveling cost?
The national leveling cost is $3 to $12 per square foot, with a typical job at $700 to $5,000 and a minimum charge of $300 to $700. Mudjacking is listed at $4 to $9 per square foot and foam lifting at $8 to $25.
Mudjacking or foam: which is better?
Both raise a slab by pumping material through small holes. Mudjacking uses a heavy cement and soil slurry, costs less and leaves larger holes. Foam is light, sets within minutes and needs holes about the size of a dime. Foam suits weak soil because it adds little weight, and it does not wash out. Mudjacking is a reasonable choice for a thick slab on firm ground. Ask whichever company you call what they will do about the cause.
Is foam lifting a permanent fix, or will the slab drop again?
The foam is permanent. The ground may not be. Foam does not rot or shrink, but if water keeps reaching the soil below, that soil can settle further and take the slab with it. Treat lifting as a long-lasting repair when the leak or drainage fault has been corrected, and as a short-term one when it has not.
Can concrete be resurfaced instead of replaced?
Yes, concrete can be resurfaced instead of replaced when the slab is solid and only the top is worn. A bonded overlay costs $3 to $7 per square foot nationally, or $6 to $20 for a decorative or stamped overlay, and $1,200 to $2,900 for a two-car driveway. An overlay hides wear and small defects. It does nothing for a slab that is sinking or moving.
My old patio has cracks and flaking. Can it be resurfaced, and how long will it last?
Usually yes, if the cracks are not moving. The loose surface is ground off, the cracks are repaired, and an overlay is bonded on. How long a resurfaced patio will last depends on that preparation and on resealing. Sun is the main enemy here, so an overlay in full afternoon exposure needs its sealer renewed more often than one under a ramada. Cracks that still move will come back through the new surface, so we tell you which ones we expect to return.
Why is my concrete spalling or flaking?
In the desert, spalling or flaking is rarely about frost. It usually comes from a weak top layer: water was added during finishing, the surface was worked too early, or it dried too fast on a hot, windy day. Salts are the other cause. Our soil and water are alkaline and high in minerals, and salt from a saltwater pool or a water softener discharge can break down the surface next to it.
Can a flaking surface be repaired without replacing the slab?
Yes. When the damage is only skin deep, a flaking surface can be repaired by grinding back to hard concrete and applying a bonded overlay. If you can dig into the slab with a screwdriver, or the flaking has reached the steel, that section is better cut out and poured again.
Why is my driveway lifting or heaving?
There is no frost heave here, so a driveway that is lifting or heaving is being pushed by roots or by swelling clay. Clay soil, found in parts of the Valley that were once farmed, expands when irrigation or storm water reaches it. A slab can also lift at a joint in summer when the panels expand in the heat and have no room to move, because the joints are packed with grit.
Can I patch a wide crack, or will the patch pop out?
A rigid patch in a wide crack that still moves will pop out, usually within a year or two of our hot days and cool nights. For a crack that opens and closes, a flexible sealant over a foam backer rod lasts much better. A wide, stable crack can be cut to a square edge and filled with a repair mortar. If the two sides are at different heights, patching is only cosmetic.
How do I fix a sunken walkway that is a trip hazard? Can a raised edge just be ground down?
There are three ways to deal with a trip hazard: lift the low panel, grind the high edge, or replace the panel. A lip of up to about an inch can be ground down to a smooth bevel in an hour or so, and that is the cheapest route. Grinding leaves a rougher, lighter strip and does not stop further movement. A bigger drop is better lifted or replaced.
