Control joints are cut so that concrete cracks where it is told to. A crack that wanders across a panel between joints, or one that has opened wider since it first appeared, says the slab is moving more than the joints can absorb. On clay that swells and shrinks, that movement comes from the ground, and sealing it only keeps water out.
When one edge of a joint rises above its neighbor, either that panel has lifted or the one beside it has dropped. Clay under a wetted edge swells and pushes up; clay that dries back shrinks and leaves a gap the slab settles into. The fix depends on which happened, so the visit checks both sides before choosing to lift, grind or replace.
A settled panel at the garage lip holds water against the slab and the stem wall. If the panel is still in one piece, it can often be lifted on cement slurry or polyurethane foam and the void under it filled. If water keeps reaching the clay below, the lift is followed by fixing the downspout, the sprinkler or the grade.
Extra paving in Gilbert usually involves two approvals: the Town's, for any work in the right-of-way, and an HOA's architectural review if the home is in an association. Width limits for Gilbert lots are confirmed per address with the Town rather than assumed from a neighboring city's code.

A driveway poured within the last twenty years shouldn’t have a crack running across a panel and a joint standing half an inch proud. When one does, driveway repair in Gilbert, AZ, starts with the ground, because the Town sits on some of the most expansive clay sampled in the Valley, under some of its newest houses. Sundial Driveway Repair is a service company offering and managing driveway repair in Gilbert and the rest of the Phoenix area, for homes and commercial properties, with the work fulfilled by licensed and insured contractors.
It starts with photos and a short description: the surface, what changed and where. The visit then looks at the entire drive, including the surface, every joint and edge, where roof and sprinkler water ends up, and how the slab meets the garage, the sidewalk and the street. Each crack is checked for width, for offset from one side to the other and for whether it crosses from one panel into the next. Hollow spots are found by tapping, and a section is sometimes cut out to see the base. On a young slab those checks separate shrinkage, which is cosmetic, from movement, which needs a different repair.
The estimate then names the method, the area and any right-of-way portion, and lists what it excludes, such as a color match between a new section and the old concrete. A narrow crack with level sides gets driveway crack repair. A sound panel that settled is a candidate for sunken driveway repair by slurry or foam, and the mudjacking vs polyjacking guide compares the two. A joint that has opened or lost its sealant is a job for expansion joint repair. Anything found that changes the scope, such as soft base under a panel, is explained before work is agreed. If the apron or curb is involved, the Town’s encroachment permit becomes part of the scope, and Town engineering inspects that work.
Summer pours are planned for the cooler hours and kept damp while curing, and the wait before you drive on new concrete is stated before work starts. The guide to driving on a new driveway explains what sets that wait.
Gilbert’s housing is young by any local measure. Census Bureau figures put the median year built at 2003, with 59.6% of the Town’s 100,336 housing units built in 2000 or later, only 4.1% before 1980, and 81.7% single-family detached houses. For driveways this young, age isn’t the issue. The ground is.
USDA soil survey samples across Gilbert show moderate or higher shrink-swell at 78.4% of points and high shrink-swell at 47.1%, mainly in Contine clay loam, with Mohall loam and Gilman loam behind it. High shrink-swell means the clay changes volume a great deal between wet and dry. Water from a sprinkler line, a drip emitter or a downspout soaks the soil at one edge of the slab and that edge rises; a dry spell shrinks it back and leaves a gap the panel settles into. Repeat that across seasons and you get a crack through the middle of a panel, a joint with one side higher, or a corner that has dropped at the garage. The same samples rate the soil as low strength at 51.0% of points, so it spreads a parked load poorly, which matters on a wide three-car drive with long panels. Soil maps describe the Town, not your lot, but on this ground it makes sense to look under the slab before choosing a repair. The guide to why driveways crack and sink walks through the mechanism in more detail.
Flooding is a minor factor. FEMA flood maps put about 1.1% of sampled Gilbert points in a special flood hazard area, and no cemented layers turned up in the soil samples, so caliche is unlikely to drive cost here. The planned-community era brings a different constraint. If your home is in an association, its architectural review sits on top of the Town’s rules for anything visible from the street, which the HOA driveway rules guide covers. A driveway extension or RV pad may need that approval before anyone pours.
On Gilbert clay, a crack that crosses panels is a symptom, so sealing it only keeps water out of the base. Lifting a panel works when the slab is whole and the water that moved it can be controlled, and driveway leveling covers what that involves; the leveling cost guide sets out the budget. Where panels have broken or the base has failed, a new section or a full driveway replacement on a corrected base is the repair that lasts. Neighboring pages for Mesa, Chandler and Tempe cover how those cities handle the same work.
Cracks or a lifted joint in Gilbert? Get an Estimate.
Send photos of the cracks and joints with something for scale, and say whether your home is in an HOA. That tells the estimate whether lifting, sealing or a new section fits and which approvals come first.
Two causes are worth separating. Hairline cracks from concrete shrinking as it cures are normal and tend to land at the control joints. Cracks that cross panels, widen or step up on one side suggest the ground is moving; USDA soil samples in Gilbert show high shrink-swell clay at 47.1% of points, mostly Contine clay loam. A soil map can't prove the cause on one lot, which is what the visit checks.
Work in the Town's right-of-way needs an encroachment permit, applied for through the Town's One Stop Shop, and permitted work there is inspected by Town engineering. The Town's supplement to the MAG specifications has called for MAG Standard Detail 250 on entrances other than rolled curb. Which edition applies, and the fee, are confirmed with the Town when the permit is applied for.
The shared Phoenix-area ranges apply: about $0.50 to $5 per linear foot to fill and seal concrete cracks, and about $4 to $10 per square foot to mudjack a settled slab, with a minimum charge of several hundred dollars on most lifting jobs. Polyurethane foam lifting has a national budgeting range of about $8 to $25 per square foot. No Gilbert-specific range is published.
If your home is in an association, its architectural rules may cover changes you can see from the street, such as widening, new material or color, or an added pad. Repairs that restore what was there may be treated differently. Check the CC&Rs and design guidelines first; across Arizona, the Community Associations Institute counts about 2,264,000 residents in more than 9,900 community associations.
It can, if the water that caused the drop is dealt with. Lifting fills the void and raises a sound panel, but clay that keeps getting wet at the slab edge will keep swelling and shrinking. Pointing downspouts away, moving spray heads off the edge and correcting the grade are what give a lift a long life. A broken or crumbling panel is replaced instead of lifted.

The wait depends on the material, the mix, the weather and the load. Here is what each one does, why Phoenix heat changes the picture, and how to protect new pavement in the first weeks.
What mudjacking and polyurethane foam lifting cost per square foot, why small jobs price as a minimum, what drainage and joint work add, and where lifting stops being the cheaper choice.
