El Monte crew troweling a fresh driveway slab flat — 21Years pouring before 2015

Our story

C-8 Licensed and Based on Peck Road

Rio Hondo El Monte Concrete is a concrete contractor owned and run from Peck Road in El Monte, CA. Ismael Duarte started it in 2015 with 21 years of the San Gabriel Valley crews behind him, and the round now takes in 20 towns, every one of them inside Los Angeles County.

The city was incorporated in 1912 and then filled up in a hurry: 13,163 people at the 1960 census and 69,892 at the next one, walnut ground turned into small-lot tracts inside a decade. That is why so much of what we break out dates from the 1950s and 1960s, and is now past the 30 to 40 years a slab laid properly is good for.

Permits are filed at Building & Safety in City Hall West on Valley Boulevard, and whoever poured the slab is the one who meets the inspector, you do not need to be home for it. liability insurance on every job is in force before a saw is started. Every estimate is measured and written on site.

The name on the license

Ismael Duarte, Who Measures It and Then Pours It

There is no estimator here and no sales call. The man who takes a tape round your lot is the man who books the truck for it, and he has been doing the second half of that job on this valley floor since 1994.

Holds the C-8, writes the estimate, finishes the slab

Ismael Duarte

CSLB C-8 in his own name, Grew up off Garvey Avenue, On the frontage at seven

Ismael Duarte was nineteen the first time he pulled a screed, replacing a frontage two streets from where he grew up off Garvey Avenue. Two decades on other men's crews followed, and what he came away with was less a technique than a suspicion. On ground this even, a slab that has broken has almost always broken over something an earlier trade left behind, and the only way to find that is to open the pad rather than look at it.

So the estimate is written at the address, on paper, with the ground opened wherever it needs opening. Nothing is priced from a satellite view and no figure is said aloud before demolition, base, depth, finish and clean-up have been set out on separate lines, which is also why a visit runs the better part of an hour. He lives in the city, and the number printed in the bar above reaches him and not an answering desk.

The C-8 sits in his own name and not a hired qualifier's, so the person the state holds to the work is the person standing on the slab while it is floated. The business carries liability insurance on every job, and the terms of its written guarantee are handed over on paper at the visit rather than described down a phone. Every estimate is measured and written on site.

“Every drive I break out on the old grid crosses somebody's trench. The concrete did not fail. It was asked to bridge a hole that was dug in 1954 and filled again in a hurry.”

Six rules that cost us money

What Does Not Change From One El Monte Lot to the Next

Six standing rules, each written down because keeping it costs this business time or money on the jobs it applies to. A rule that costs nothing is a preference, and nobody needs to read a preference.

Steel goes in before a price

A bar is pushed through the pad at four or five points during the visit. What it finds sets the dig, and the dig is most of the figure.

The street is read first

Your road is read against the city's published cut moratorium before a date is offered, so it turns up at the estimate and not after a deposit.

Named before a truck is booked

Base class, mix strength and depth are printed on the estimate, and the docket that rides in with the concrete goes into your job file.

One crew, nobody hired in

The same men break it out, form it and finish it. No labor is brought in for an afternoon to hold a date that was promised too tightly.

A claim is one phone call

Guarantee wording is on the estimate before any signature, identical job to job, so a problem in 2034 starts with the number you rang in 2026.

Answerable on Peck Road

No franchisor sits above this name and no call center in front of it. The office is at 3650 Peck Rd and the owner lives in the city.

Eight dates

How a Crew Ends Up Working Out of El Monte

Twenty-one years on other people's crews, then eleven under this name. Nothing below is an award or an anniversary. Each date changed something about how the work here is scheduled, priced or dug.

1994

First screed on a drive crew

Ismael Duarte took a laborer's job at nineteen, replacing frontages on the tract streets between Durfee and Lower Azusa.

2003

Moved to the finish end

Nine years in he stopped placing concrete and began finishing it, the half hour at the end that settles how a slab looks for thirty years.

2010

Ordering the mix himself

He was standing pours on shop floors along Valley Boulevard and calling the trucks in, still working under somebody else's license.

2015

The C-8 in his own name

Rio Hondo El Monte Concrete opened with one truck and a round that reached no further than Rosemead, South El Monte and Temple City.

2018

First permit filed in our name

Right-of-way work came onto the books, which meant a city business license and a certificate naming El Monte as additional insured.

2021

The round stopped growing

Coverage settled at 20 towns inside 25 miles, every one in the same county, from Sierra Madre under the foothills down to Whittier.

2024

City Hall shut on Fridays

The counter went to Monday through Thursday that May, so filing moved to the front of the week and pour dates are set around it.

2026

Eleven years under this name

16 concrete services and 20 towns, with one owner still writing every estimate at the address and calling back within 1 business day.

All of it checkable

Eight Records in El Monte That Are Not Ours to Edit

Each card points at something that sits outside this website, a state register, a certificate, a printed docket, a city file. Look one up before you ring, and ring somebody else if it does not stand up.

C-8 on the register

The Concrete class comes from the California Contractors State License Board, which lists it under this name on a register open to anybody.

City business license

El Monte issues its own business license and ours is current, which is one of the three papers Public Works wants with an encroachment application.

Certificate of insurance

We carry liability insurance on every job. On right-of-way work the certificate names the City of El Monte as an additional insured party.

Workers covered as well

Workers' compensation covers every person who sets foot on the lot, so an injury on your frontage answers to our policy and not to yours.

Built to the state code

Footings and structural slabs follow the California Residential Code, and its 30-inch line is what settles whether a job is permitted work at all.

Guarantee before money

Every job carries a written workmanship guarantee against defects in how it was built, worded that way on the estimate you sign.

The docket, years later

Mix design and yardage arrive printed on the delivery docket with the concrete. Ask for it at the pour, or ask for the copy nine years afterward.

Reviews we cannot edit

Nothing on Google, Facebook or the BBB is posted under a parent company's name. Read the streets named in them before you read the stars.

Counted, not chosen

Six Numbers Behind the Round From Peck Road

Nothing below is rounded up. Three come off the coverage list and the services list, one is the city's own rule about cutting a road, and two are dates out of the license record.

The office and the round

Peck Road, and the Valley Floor Around It

The office is at 3650 Peck Rd, on the east side of a city of 9.65 square miles that sits 299 feet above the sea and drains one way across the whole of it. There is no showroom in it and nothing to look at: it holds forms, string, a saw and a filing cabinet, and on a working morning it is locked again by half past seven.

The calls sort themselves by era. Subsistence Homestead cottages on the west side, put up under the New Deal in the 1930s, were each given one narrow strip of concrete and a surprising number of those strips are still down. The tracts that took the walnut ground in the 1960s are where the driveway and garage floor work sits. Out toward Flair Park it is loading aprons and yard slabs instead, poured at night between deliveries.

Past the city line the round runs 25 miles and never leaves Los Angeles County: San Gabriel, Rosemead and Temple City within minutes, Arcadia and Sierra Madre up against the foothills, Whittier and Pico Rivera on the far side of Whittier Narrows. The plants we draw from sit inside that circle too, so no load spends its first hour of life on the 10.
