Why Riverside calls us
A driveway cracks from underneath. Old fill settles, the slab bridges the soft spot and breaks over it, and a patch on top lasts a season. Dig out what is under it, compact a base in layers and pour 4 to 6 inches to the load, and the same drive carries cars for 30 years.
Riverside Concrete Pro was founded in 2021 by Marco Delgado, who spent 15 years on Inland Empire flatwork crews first, and he runs the pour on every drive. Riverside is a century of housing on one map, from 1920s bungalows in the Wood Streets to 2000s tracts out in Orangecrest, and the ground under each of them is a different job.
Driveways are built under a CSLB C-8 concrete license with liability insurance on every job, to the California Residential Code, and any work at the curb or across the public walk is built to the city's own width and cross-slope standards. The work carries a written workmanship guarantee against defects in how it was built.
Warning signs
A crack that crosses the slab rather than following a joint is the ground moving, not the surface wearing. Filling it hides the line for a winter and does nothing to the void underneath, which keeps growing. The slab comes out and the base is rebuilt.
A step between panels means the fill under one has compacted and the other has not. On Riverside lots trenched since the 1880s it is the commonest failure of all, and it worsens every winter as water runs into the gap and washes fines out.
A driveway should shed water to the street within minutes. A puddle that sits means the fall has gone, usually because the slab settled, and standing water softens the base further. It is the fault that compounds fastest, cause and consequence being one.
Surface flaking that shows the stone underneath is the top of the slab breaking down, from a pour finished too wet or never sealed. It does not threaten the structure for years, but it will not stop, and resurfacing bonds to a layer already letting go.
What’s included
These are standard on every driveway we pour, with no add-ons, and each answers one of the two things that break a drive here: ground that was filled decades ago, and heat that pulls the water out of a slab before it has set.
The old slab is broken out and hauled the same day, down to soil. Nothing is poured over an existing drive, because the crack comes through again.
The ground is probed for soft spots and old fill before any base goes in. What the probe finds sets the depth we dig, and the depth sets the price.
Class 2 base laid and plate-compacted in layers, not one lift, so the drive sits on a drained bed that will not settle in the first wet winter.
4 inches under cars, 5 to 6 where a truck or an RV parks, in 3,500 psi ready-mix. The thickness we pour is written on your estimate.
Control joints go in within 12 hours, spaced 2 to 3 feet for every inch of thickness, so the shrinkage crack lands in a line you expected.
Every edge is tooled by hand and the surface broomed across the line of travel, which is what gives grip when it is wet and saves the arris.
Curing compound goes down the same day and the slab is kept damp for a week. In a Riverside July that is a sound slab against a crazed one.
We walk the drive against the estimate with you, base, thickness, joints, finish, and hand over the written guarantee before the job closes.
Your options
Four ways to build a drive here, judged on how long each lasts, what it suits, what it asks of you and how long the crew is on your frontage. All four sit on the same compacted base, because that is the half that decides the rest.
| Option | Lifespan | Best for | Upkeep | Time on site |
|---|---|---|---|---|
| Broom-finish concrete | 30 to 40 years | Any drive from the street to the garage | Reseal every 4 to 5 years | 1 to 2 days, then 7 to cure |
| Stamped concrete | 25 to 30 years | A frontage meant to be looked at | Reseal every 2 to 3 years | 2 to 3 days, then 7 to cure |
| Exposed aggregate | 35 years or more | 1920s and 1950s streets, and shaded lots | Reseal every 4 years, rinse each spring | 2 days, then 7 to cure |
| Interlocking pavers | 30 to 50 years | Drives over old fill that may still settle | Sweep sand into the joints once a year | 2 to 3 days, no curing |
Broom finish costs least to lay, stamped the most to keep, and pavers lift and reset where concrete has to be broken out.
Local knowledge
Two things decide a drive here, and neither is the concrete. Riverside lots have been graded and trenched since the 1880s, so what sits under an old driveway is rarely native ground.
Both are answered under the surface and before 8 AM. We probe the subgrade on the estimate visit, dig out fill to firm ground and compact base in layers, so the slab is bedded rather than bridging. In summer the pour starts at first light and the surface is kept wet for the full seven days.
We pour drives across the Wood Streets, Magnolia Center, Arlington, La Sierra, Canyon Crest and Orangecrest, and out into Colton, Norco and Eastvale. The older the street, the more of the job is under the concrete, which is why the estimate is measured at your property and not over the phone.
Our process
A drive runs from the measurement to the day you park on it. One crew, one written figure, and any permit for work at the curb filed by us before the saw starts.
Marco Delgado walks the drive, measures it, checks the fall to the street and probes for old fill. The estimate is written before he leaves.
You pick the thickness for what parks on it, and the finish. Work at the curb takes an encroachment permit from Riverside Public Works.
Day one the old slab is broken out and hauled for crushing, then the fill is dug to firm ground and the subgrade proved before base arrives.
Class 2 base compacted in layers, forms set to the fall, then the pour and the broom finish, run by the owner, and before 8 AM in summer.
Joints cut within 12 hours, curing compound down, the site swept. You walk the drive with the owner and take the written guarantee.
What moves the estimate
Size sets the floor and the ground sets the rest. A two-car drive is about 400 to 600 square feet; what changes the number after that is what comes out and what has to go back in underneath. Every estimate is measured and written on site.
Fill dug to firm ground is the biggest variable on an older lot. A drive on native ground needs base; one over a filled trench needs digging first.
4 inches under cars, 5 to 6 under a truck, an RV or a trailer. Every extra inch is a quarter more concrete and more base beneath it.
A drive that stops at your line is one job. One that rebuilds the approach is right-of-way work, with a permit and an inspection.
A broom finish is the baseline; stamped or exposed aggregate adds hands at the pour. A lot that falls toward the house adds a drain.
The figure comes from the visit, free and in writing, and we call back within 1 business day to book it. (951) 584-0685 or send us a message.

Reviews
Reviews left on Google, Facebook and the BBB by homeowners whose drives we replaced. All three are about driveway work rather than patios or slabs.
“Our 1920s place in the Wood Streets had a driveway that was more crack than concrete. They took out 480 square feet, dug the old fill out to firm ground and poured 5 inches. Marco was there for the pour and the joints were cut the same afternoon.”
“We park a work truck and a trailer, so they poured ours at 6 inches instead of the 4 the last contractor quoted. Two winters and a summer of 100-degree days later there is not a line in it. The estimate itemized every part of the job before we agreed.”
“The drive fell back toward the garage and flooded it twice. Riverside Concrete Pro re-graded the whole thing, put a channel drain across the apron and poured 460 square feet. It has rained hard twice since and the garage has stayed dry both times.”
FAQ
Thickness, base, joints, curing, permits and the guarantee, answered for a Riverside driveway rather than for concrete in general.
4 inches is the minimum under cars and 5 to 6 inches where a truck, an RV or a trailer parks. Thickness is the cheapest thing on the estimate and the only one that cannot be fixed afterward: a drive poured an inch light cracks under normal use inside a few years and no repair puts it back. We pour to what parks on it, and the figure is written on the estimate you sign.
No, and anyone offering to should be asked why. An overlay bonds to a slab that is already failing, and every crack in the old drive reflects through the new one within a season or two. It also raises the surface, which throws the fall to the street and the height at the garage threshold. The old slab comes out and the ground under it is rebuilt.
Seven days for a car and 28 days for anything heavy, a truck, an RV or a delivery lorry, which is when the concrete reaches its full strength. Foot traffic is fine after 24 to 48 hours. Parking early does not crack it that day; it presses the slab into a base that has not finished taking load, and the crack arrives months later.
Because most Riverside lots have been trenched, re-graded or built over since the 1880s, and fill compacts unevenly for decades. A slab poured on it bridges the soft spots until it breaks over one. We probe the subgrade on the estimate visit and dig to firm ground before base goes in, which is why two drives of the same size can be different jobs.
Not for the part inside your lot line: the California Residential Code exempts driveway slabs. The driveway approach, the curb and the public walk are right-of-way and need an encroachment permit from Riverside Public Works, with an inspection. We file it and meet the inspector, so the counter is not your problem.
Two to three feet apart for every inch of thickness, so a 4-inch drive is jointed at about 8 to 12 feet, in panels as close to square as the shape allows. They go in within 12 hours of the pour. Concrete shrinks as it cures and will crack somewhere; the joint decides that it happens in a straight line you were expecting.
Yes, and every 4 to 5 years on a broom finish. Unsealed concrete is porous, so oil, brake fluid and water soak in and stain permanently, and the ultraviolet load this far inland is harder on a surface than it is on the coast. A stamped or colored drive needs it every 2 to 3 years, because the color is what fades first.
Yes. Every drive carries a written workmanship guarantee against defects in how it was built, the base, the thickness, the joints and the finish, with its terms on the estimate you sign. It does not cover staining, wear, or ground movement beyond what the joints control. If the fault is in how we built it, we come back and make it right.
Service area
The eight nearest towns we pour driveways in, with the straight-line distance from Riverside. The full coverage list reaches 25 miles out.
Four jobs that most often go in alongside a driveway, or instead of one, each on the same base, by the same crew, on the same estimate.
The same base and the same joints, out the back: a 4-inch slab poured in a morning and cured seven days.
Where the drive cuts into a slope, a poured wall on footings to 24 inches holds the bank off the concrete.
The public walk across your frontage, replaced 4 inches thick with the encroachment permit pulled and met.
The slab the drive runs up to: a new 5-inch floor, jointed on a 12-foot grid and sealed so it hoses clean.
Call or send the form and someone rings you back within 1 business day. The visit is free, the estimate is written at your property, and nothing is owed if you leave it there.
