Concrete Services for Riverside Homes and Businesses
Ironline Riverside Concrete pours concrete across Riverside and the towns around it. Whether it is a full driveway replacement, a failing slab taken out and re-poured or stamped work, the crew builds to California code.
Concrete Patio Construction
Cracked or ponding patio? A new 4-inch slab on compacted base, falling away from the house and jointed the same day, sits flat for 30 years.
Stamped Concrete Services
Want the look of stone without laying it piece by piece? Stamped concrete takes the pattern and color you pick, resealed every 2 to 3 years.
Concrete Sidewalk Building
City notice on the walk out front? We replace panels 4 inches thick over a root barrier, hold the cross fall under 2 percent, file the permit.
Garage Floor Concrete
Dusty, cracked or oil-stained garage floor? A new 5-inch slab with joints on a 12-foot grid gives a flat, sealed floor that cleans with a hose.
Decorative Concrete
Gray slab beside an old brick porch? Color, acid stain, exposed aggregate and ground finishes, chosen against the house in daylight.
Concrete Retaining Walls
Bank sliding or a wall leaning out? A poured wall on footings to 24 inches, drained behind the stem, and permitted where it stands over 4 feet.
Concrete Floor Installation
Bouncing wood floor or an addition to floor? Interior slabs cast on a 15-mil vapor retarder and troweled flat enough to lay wood straight on.
Concrete Pool Decks
Cracked or scorching pool deck? A new slab over re-compacted backfill, jointed at the coping and faced light, flat and crossable barefoot.
Concrete Steps Construction
Steps dropped, cracked or with no rail? We divide the rise again, dig footings past the worked grove soil and cast the flight whole.
Slab Foundation Building
Building an ADU or an addition? An engineered slab, over old fill dug out to firm ground, with the reinforcement inspected before the pour.
Foundation Installation
New foundations for additions, ADUs and shops, a stem wall on footings, or piers drilled past the layer this city has spent 150 years moving.
Concrete Parking Lot Building
Rutted asphalt or a cracked lot? A commercial slab, 6 inches under the aisles with joints on a 15-foot grid, poured in weekend phases.
Concrete Footings
Footings under an addition, a wall or a set of posts, taken below the layer people moved, steel lapped through and the trench signed off open.
Foundation Raising
Floor dropped at one end, or a footing you can scrape away by hand? The house comes up on cribbing and down onto a new engineered foundation.
Concrete Cutting
Trench, doorway, sleeve or joint grid cut into concrete that is staying put. The line is scanned for pipe, conduit and strand before it is painted.
Our 4-Step Concrete Process
Four steps from your first call to the finished slab. Marco Delgado measures the job at step two and is on site for the pour at step three.
Request and Schedule
Call or use the form. You hear back within 1 business day, and the free on-site visit is booked for a day inside the week.
Measure and Estimate
We walk the lot, probe the subgrade and check the fall, then write an estimate itemizing demolition, base, pour, finish and cleanup.
Permits and Pour
Once you approve it we file any permit, book the crew and run the job: demolition, base, forms, the pour and the finish.
Final Walk-Through
We clear the site and go round the slab with you against what the estimate said, base, thickness, joints, finish, then close it.
Why Homeowners in Riverside Choose Us
CSLB C-8 Licensed, Insured
The license is held with the California Contractors State License Board in the C-8 concrete classification, checkable on their register by name. The insurance has followed this crew across Riverside and San Bernardino counties, so a job over the county line is covered too.
In Riverside Since 2021
Marco Delgado started the business here in 2021 after 15 years on Inland Empire crews. The decomposed granite under the Wood Streets, the river sand on the Fairmount flats and the counter at Building & Safety are known first-hand, not read about.
Free On-Site Estimates
The visit costs nothing, and on a Riverside lot it starts with a probe rather than a tape: what is under a driveway laid before the war decides the base, and the base decides the figure. Then demolition, base, pour, finish and cleanup, itemized in writing before you decide anything.
Workmanship Guaranteed
Every pour carries a written workmanship guarantee against defects in how it was built. The claim we see most here is a panel dropped where old fill was never dug out, which is ours, not the ground's. Normal wear and seasonal movement are not defects, and we say so up front.

Customer Reviews
What Homeowners Around Riverside Say
Ironline Riverside Concrete is rated 5.0 stars on Google, Facebook and the BBB by homeowners across Riverside County and San Bernardino County.
“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.”
“The city tagged the sidewalk panel outside our house on Magnolia. Ironline pulled the encroachment permit, met the inspector and poured the 5-foot section to the cross slope the city wanted. I never had to go to the counter myself.”
“We wanted a patio behind the house in Canyon Crest that would take the afternoon sun. They poured 380 square feet in a broom finish, cut the joints on a 10-foot grid and sealed it at 28 days. Two summers on it has not moved a millimeter.”

Local Knowledge
What Working in Riverside Involves
A century of housing on one map, ground that changes street by street, and two counters to satisfy: three things every estimate we write accounts for.
Riverside was laid out in 1870 and incorporated in 1883, and its housing runs the whole span since: bungalows from the 1900s and 1920s in the Wood Streets and around downtown, post-war tracts through Arlington and La Sierra, and 1990s and 2000s subdivisions in Orangecrest, Mission Grove and Canyon Crest. A driveway poured for a Model A is 4 inches of unreinforced concrete on native dirt, and it is still out there.
The ground changes with the terrace you are on. The flats near the Santa Ana River and Fairmount Park are river sand and gravel that drain fast but settle under fill; the older benches under the Wood Streets and Victoria Avenue sit on decomposed granite and sandy loam; and the arroyos between them carry clay that swells above an Expansion Index of 20, the line California code draws. Your own lot is on the USDA Web Soil Survey.
Building permits come from Building & Safety at the City of Riverside, and anything at the curb, in the parkway or across the public walk takes a separate encroachment permit from Public Works. We file both and meet the inspector. We work the whole city, from the citrus-era streets off Victoria and Magnolia to the newer tracts east of the 215, and measure on site because the ground under them differs.
Concrete vs. Asphalt vs. Pavers for a Riverside Driveway
Concrete wins on a Riverside frontage, and the reason is the ground as much as the heat: a slab spans the soft spots that a century of trenching left behind, where asphalt sinks into them and pavers drop one at a time.
| Option | Lifespan | Ready to use | Maintenance | In our heat and ground |
|---|---|---|---|---|
| Poured concrete | 30-40 years | 24-48 hrs on foot, 7 days for cars | Reseal every 2-3 years | Stays rigid at 110 degrees; joints absorb the movement |
| Asphalt paving | 15-20 years | Cars back on in 2-3 days | Sealcoat every 2-3 years | Softens above 100 degrees |
| Interlocking pavers | 25-50 years on a good base | Walk on it the same day | Re-sand joints every 1-2 years | Rides soil movement, but ruts and weeds at the joints |
Asphalt costs least to lay and most to keep. Pavers cost most to lay and least to keep, and lift and reset where old fill settles. Concrete sits between on both.
What Every Riverside Homeowner Should Know About Concrete
Why does heat over 90 degrees crack a new slab?
Because the surface dries before the concrete under it has gained strength, and the shrinkage tears it. Riverside runs past 95 degrees for most of July and August, so we pour before 8 AM and keep the surface wet for the 7-day cure the Portland Cement Association sets out.
Does the base matter more than the concrete?
Yes. Most failures start underneath, not in the slab. A compacted gravel base spreads the load and drains water from the underside; without it the slab bridges soft spots and cracks where the ground gives. It is the step nobody can see once the driveway is poured.
What does a century-old lot hide under the driveway?
Fill, usually. Riverside lots have been re-graded, trenched and built over since the 1880s, and old fill compacts unevenly under a new slab. We probe on the estimate visit rather than after demolition, because what is down there sets the base depth.
Where do control joints go, and what do they do?
Grooves cut into fresh concrete 2 to 3 feet apart for every inch of thickness, and they decide where a crack lands. Concrete shrinks as it cures and will crack somewhere; a joint gives it a line to follow instead of a wandering one. We cut them the day it is poured.
When does concrete work in Riverside need a permit?
Inside your lot line, usually not: the code exempts a driveway or walk under 30 inches above grade. It never names a patio slab, so we confirm that at the counter. Curb, parkway and public walk are right-of-way and take a Public Works encroachment permit.
How thick should the slab be for what it carries?
4 inches under feet and cars, 5 to 6 inches under trucks, RVs or a workshop floor. Thickness is the cheapest thing on an estimate and the hardest to fix later: an inch short cracks under normal use inside a few years. What we pour is written on your estimate.
Concrete Questions Riverside Homeowners Ask
Straight answers on driveways, patios, slabs and the ground under them in Riverside: cost, thickness, base, joints, sealing, permits, timing and the guarantee.
How much does concrete cost in Riverside?
Thickness sets the price before size does: every extra inch on a 4-inch slab is a quarter more concrete, and more base under it. After that it is how much old surface comes out, whether the fall needs drainage, and the finish. We measure all four on a free on-site visit and put the number in writing.
How much does a concrete driveway cost in Riverside?
A driveway is priced on its square footage, its thickness and what is under it. A 1920s lot with old fill and a tree at the edge is a different job from a 1990s tract drive on native ground, and the demolition and base are where the difference lands. We measure and write it on site, itemized line by line.
How much does a concrete patio cost in Riverside?
A patio is usually 4 inches on compacted base, so the number moves on size, access and finish. On the older Riverside streets access is what moves it most: a lot with an alley or a wide side gate takes a truck, and one on a 1920s frontage takes barrows, which is labor rather than material.
How thick should a concrete driveway be in Riverside?
4 inches is the minimum under cars and 5 to 6 inches where trucks or RVs park. Thickness is the cheapest insurance on the job: a slab poured an inch too thin cracks under normal use within a few years, and no repair restores it. We pour to the use, and the thickness is written on the estimate.
Why does the gravel base matter more than the concrete?
Because the base is what the slab rests on, and most failures start underneath. A compacted gravel base spreads load and drains water away from the underside. Without it the slab bridges soft spots and cracks where the ground gives. On old Riverside fill we excavate deeper and compact in layers.
What are control joints and where do they go?
Control joints are grooves cut into fresh concrete 2 to 3 feet apart for every inch of thickness. They give any future crack a straight line to follow rather than a wandering one. On a Riverside lot with old fill under it we joint tighter, because the ground below is more likely to move than the concrete above.
Does Riverside soil cause concrete to crack?
It can, and which soil you have depends on the street. River sand near Fairmount drains well but settles under fill; the clay in the arroyos swells in a wet winter and shrinks by August, lifting a slab from below. We probe on the estimate visit, excavate deeper where the ground calls for it, and joint the slab so movement lands in a line.
What time of year is best for concrete work in Riverside?
Late fall through early spring, when afternoons stay under 90 degrees. Riverside runs past 95 through July and August, and heat pulls water out of the surface before the slab has set. We pour in summer too, starting before 8 AM, with the surface kept wet for the full seven days.
Does concrete need sealing in Riverside, CA?
Yes, and more often here than on the coast. Unsealed concrete is porous, so oil and water soak in and stain permanently, and the ultraviolet load inland fades colored and stamped surfaces faster. Reseal every 2 to 3 years, sooner on a slab that takes full afternoon sun.
How long does a concrete project take from start to finish?
3 to 5 working days on site for most residential jobs, plus curing, and on an older Riverside lot the first two days are demolition and digging out fill, which is the part that varies. Foot traffic at 24 to 48 hours, cars at 7 days, anything heavy at 28.
Do I need a permit to replace a driveway or patio in Riverside?
Not usually, inside your lot line: the code exempts sidewalks and driveways under 30 inches above grade. A patio slab is not on it, so we check the job against the city's own exempt work rather than assume it. The curb, the parkway and the driveway approach are right-of-way and take an encroachment permit from Public Works; a retaining wall over 4 feet needs a building permit. We file both.
Is the concrete work guaranteed or warranted?
Yes. Every job carries a written workmanship guarantee against defects in 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.
