Concrete contractor in El Monte, CA - driveways and patios that drain right
Monrovia Concrete is a concrete contractor based in Monrovia, CA. We pour driveways, patios, walks, garage floors and footings for homes in El Monte, plus walls, foundation work and paving for lots and shops.
El Monte as we see it from the driveway
El Monte sits in the middle of the valley, with Temple City and Arcadia just to the north. Most of the homes we see here are single-story houses on flat, fairly narrow lots. Many have a long driveway running back along the side to a garage or a back unit. The busier roads are lined with shops and small lots that need paving too.
That flat ground is what we plan around. Water doesn't drain off a level lot by itself, so it goes wherever the concrete sends it.
What to know before a concrete job in El Monte
Whether your job needs a permit is the city's call. El Monte's Building Department handles plan review, permits and inspections for projects in the city, and Public Works issues permits for work on public property. We check with them before we set a date, and if a permit is needed we sort out who pulls it and have it in hand before we dig. That means the permit, when there is one, usually sets the start date. For public-property work the city asks the contractor to show a valid El Monte business license, a valid contractor license and insurance that names the city. Ask any contractor you're comparing to show you those. We're fully licensed and insured, and we expect you to ask.
Most of what we pour in El Monte is the same flatwork we do across the valley, from Monrovia over to Pasadena. Flatwork means driveways, patios, walks and garage floors. The price here usually turns on four things. The first is the size of the slab. The second is how much old concrete has to be broken out and hauled. The third is how much base we have to dig out and replace. The last is whether the truck can reach the pour or we're moving concrete down a narrow side yard. The schedule turns on the permit and the weather. The written estimate lists each of those for your job, so you know what you're paying for.
Why El Monte driveways and patios crack, sink and hold water
A lot of the slabs we break out here are older driveways on flat lots, and the trouble is usually the same. Water had nowhere to go. It pooled against the house or soaked in at the edges until the subgrade softened and let the concrete sink. The subgrade is the dirt the slab sits on. We dig down to firm ground, pack a solid base and set the slope so water runs to the street or a drain instead of the garage. If the budget gets tight, I'd rather you skip a fancy finish than cut corners on the base. Nobody sees the base on day one, but it's what's still holding the slab up years later.
Summer heat is the other thing. Concrete poured in the middle of a hot afternoon dries too fast on top, and the surface ends up weak and dusty. So we start pours early and keep the slab damp while it cures, which is the slow hardening that gives it strength. You'll be back on it on foot before you can park on it, and I'll tell you when each is safe. A patterned patio from our stamped concrete services goes through the same steps.

I come out and measure
I look at the job myself, measure it and ask how you'll use the concrete, whether that's daily parking, a patio table or a trailer. That tells me how thick the slab should be and what goes under it.

The estimate spells out what's in the price, like tear-out, hauling and base work, so you can compare it line for line with anyone else's. Take your time with it.
We check with the city
Once you say go, we check with the El Monte office that covers your address before we set a date. If a permit is needed, we get it in hand before work starts.
We pour and walk it
The crew I trained preps the base, sets the forms and pours, and I'm usually there on pour day. When it's done, I walk it with you before we pack up, and the work is backed by our satisfaction guarantee.

Concrete questions from El Monte homeowners
Who handles building permits for concrete work in El Monte?
The city's Building Department is the main contact for plan review, permits and inspection on projects inside El Monte. Its counter takes applications in person with no appointment needed. The city's permit applications page also lets you check whether your address is actually inside the city. Counter staff will tell you if another department applies to your project, and you can reach City Hall at 626-580-2001.
How do I get a permit to replace the sidewalk or driveway approach in front of my El Monte house?
The sidewalk and the approach at the curb usually sit on public property, so that work goes through the city's Public Works Department. No work can be done there until the permit is in hand. The contractor also has to show the license and insurance paperwork mentioned above before the city issues it.
Which building code applies to a concrete slab or footing in El Monte?
Projects submitted for a permit in El Monte now are designed to the 2025 California Building Standards Code, along with Los Angeles County's amendments. An application filed before 2026 can keep the code that was in effect when it was filed, as long as its plan check hasn't expired. Once it expires, it takes a new application under the new code. If you have older plans sitting in a drawer, bring them out at the estimate and we'll go over them.
How much does a new concrete driveway cost in El Monte?
I give you a number after I've measured, because the choices you make move it as much as the size does. A thicker slab with rebar costs more. Rebar is the steel inside the slab that holds it together if it cracks, and it's worth having where heavy trucks park. A plain broom finish costs less than stamped or colored concrete. A broom finish is a light texture swept across the surface for grip. If the job reaches the sidewalk or curb, the city's Public Works fees depend on the type of work and the staff hours it takes to review and inspect it.
Does El Monte's earthquake rating change how footings and foundations are built?
Yes. The city's design criteria put El Monte in Seismic Design Category D, unless a soils report for your property sets a different category. That rating is part of what footings and slab foundations are designed to. If your lot has a soils report, dig it out before I come over.
How do I keep a new concrete driveway from cracking?
Plan where it cracks, because concrete shrinks as it hardens and every slab cracks a little. Besides the base work above, we cut control joints. These are shallow grooves that give the slab a straight line to crack along. We cut them on time, so the slab doesn't pick its own path across your driveway. Most cracks I've torn out happened because nobody planned the joints or nobody fixed the drainage, so I settle both before we pour.
