Driveway heaved at the joints, a walk that trips the mail carrier, or footings for a new wall on a rocky slope? We break out the old concrete, rebuild what is under it and pour it back with joints where they belong — apron permit and fire-access rules handled. One licensed contractor, start to cure.

Rancho San Diego concrete by the numbers
With 4,155 of Rancho San Diego’s 8,267 homes built in the 1980s, a lot of driveways, walks and patios were poured within a few years of each other and are now reaching forty together. The usual signs are slabs lifted at a joint, corners broken off where a car turns, and sections that have settled away from the garage. The usual fix is not a patch on top but replacement from the base up.
What comes out of the ground matters as much as what goes in. A 2021 County-filed soils report for a site on Sundale Road found granitic rock within 3 to 12 feet everywhere it dug, and gave the earthwork factors: topsoil shrinks 10–15% when compacted, while granite that has to be ripped bulks up 12–18% — and 18–25% if it is blasted. Rock takes more trucks to haul than the hole suggests, so footing trenches and driveway cuts on hillside lots are priced from a measured excavation, not a guess.
Structural and flatwork concrete, finished by hand. Mixes, steel and curing are covered on our county-wide concrete page; for the community overview see our Rancho San Diego page.
Driveways
The old slab broken out and hauled, the base dug to firm ground and recompacted, steel on chairs, and new concrete in broom, colored or exposed-aggregate finish — with control joints laid out so the next crack, if it comes, runs straight.
Aprons
The section between your driveway and the street sits in the County right-of-way. We draw it, take out the encroachment permit, call DigAlert, and pour it to the permit.
Flatwork
Front walks lifted by tree roots, side-yard paths that hold water against the house, and entry steps with uneven risers — reset to a fall away from the foundation.
Footings
Wall footings, pads for sheds and equipment, and footings for patio covers — kept back from slope faces and below nearby swales as the soils engineer specifies, and keyed to rock where it is shallow.
Decorative
Decorative finishes for patios and drives where the HOA or the street calls for something other than plain broom, sealed to hold the colour.
Slabs
Garage, ADU and patio-cover slabs on whatever your lot has: granite that needs little but digging, or swelling clay that needs a designed slab under the code’s expansive-soil rules.
The soils engineer on Sundale Road set footings next to slopes at least 7 feet horizontally from the footing’s edge to the slope face, and footings within 5 feet of a drainage swale deep enough to sit below the swale bottom. Allowable bearing was 2,000 psf. Where a pad mixes cut rock and fill, the report has the shallow side over-excavated at least 3 feet so the slab does not sit half on rock and half on fill — a common cause of a crack straight across a garage.
On the other side of the ledger, a study on Jamacha Boulevard in neighbouring Spring Valley expected most of its soil to be expansive, with an expansion index above 20, in clays of the Sweetwater Formation. The California Residential Code sends slabs on soil like that to engineered design. And every slab shrinks as it dries, roughly 1/16 inch per 10 feet, so joints go where we choose rather than where the concrete does.
County PDS rules govern concrete here. Walks, patios and driveways no more than 30 inches above adjacent grade are on the County’s list of work exempt from a building permit, but the County code also has its own section on residential driveways, so we confirm with PDS for each driveway rather than assume. Footings and slabs for structures are permitted with the structure. The apron, where your driveway meets a County street, needs a DPW Encroachment Permit — $217, $87 to renew, with drawings and a DigAlert 811 ticket before excavation.
San Miguel Fire & Rescue protects Rancho San Diego, and its published access rules apply wherever a driveway is the fire access road: 16 feet wide for one or two homes, a 20% maximum grade, a deep broom finish across any stretch steeper than 15%, a surface that carries 75,000 pounds, and access within 150 feet of every part of the building. On a long or steep hillside drive those numbers shape the layout; we confirm with the district which ones apply to your lot.
Three ways to deal with a forty-year-old driveway, and when each makes sense.
| Option | When it works | What it does not fix | Lifespan outlook |
|---|---|---|---|
| Cut out and replace a section | One broken panel, sound base elsewhere | Colour match to old concrete | Good for that panel |
| Overlay or resurface | Surface wear only, slab still flat | Heave, settlement, root lift | Short if the slab moves |
| Full replacement | Lifted joints, settled edges, many cracks | — | A new base and a new start |
| Switch to pavers | You want lift-and-relay repairs later | Costs more per square foot | Units can be reset for decades |
Overlays and coatings are a different trade; we tell you honestly if one would do. For paver options see our Rancho San Diego pavers page.
We measure the area, find out why the old concrete failed — roots, water, soft base or a cut/fill line — and check whether the drive is a fire-access road.
A written price with demolition and haul-off itemised; encroachment permit for the apron and any structural permit filed by us.
Old concrete broken out and removed; rock in the excavation measured, not guessed.
Firm ground, aggregate base compacted in lifts, forms to line and grade, rebar on chairs, joints marked.
Placed, screeded and finished — broom, colored, stamped or exposed — with joints cut on time.
Kept moist through early cure, kept off until it is ready, and handed over with a written workmanship guarantee.

| Project | Typical range |
|---|---|
| Driveway (standard finish) | $8–$15 per sq. ft. |
| Standard slab / flatwork (reinforced, 4") | $7–$13 per sq. ft. |
| Stamped / colored / decorative | $11–$23+ per sq. ft. |
| Concrete demolition and removal | $1.30–$2.10 per sq. ft. |
| National average, 24 × 24 ft driveway, 5 in (Fixr, 2025) | $5,184 |
| County encroachment permit (apron) | $217 fee |
Our ranges are for comparison, not a quote; the Fixr figure is a national cost-guide average, not a San Diego price.
Different streets, different reasons the old concrete gave up.

Straight answers before you hire. Anything else — call, and Shaun answers it himself.
Call (619) 581-2492For the apron in the County street, yes — a DPW Encroachment Permit ($217, $87 to renew) with drawings and a DigAlert ticket. For the driveway on your lot, County rules list flatwork under 30 inches as exempt but also have a separate driveway section, so we confirm with PDS for your job.
Usually a mix of drying shrinkage, tree roots, water getting under the edges and, on some lots, a slab sitting across a line between cut rock and fill. Concrete shrinks about 1/16 inch per 10 feet as it dries, so some cracking is normal; joints decide where it goes.
Only if the old slab is flat and stable and the extra height works at the garage and the street. Most forty-year-old drives have moved, and an overlay follows the movement. We tell you if an overlay is worth it, but we usually recommend replacement.
Because ground varies street to street. A soils report on Sundale Road found granite within 3 to 12 feet, and noted that ripped or blasted rock bulks up 12 to 25%, so it fills more trucks than the hole’s size suggests. We measure the dig and price it before we start.
Under the access rules San Miguel Fire & Rescue publishes, 20% at most where the driveway is the fire access road, with any stretch over 15% in concrete with a deep broom finish across the slope. We confirm with the district for hillside lots.
Usually close. We bring pattern and colour samples to compare in daylight; exact matches to forty-year-old decorative concrete are not always possible, and we will say so.
