Vincent is a few square miles of postwar tract housing on the flat floor of the San Gabriel Valley, and its slabs were poured when it was built. A driveway here has carried cars for 70 years.
The ground is not the problem. The valley floor under Vincent is alluvium off the San Gabriel Mountains, sandy and free-draining, and it does not heave. The problem is the slab. The 1950s builders poured driveways and garage floors 3 inches thick with no steel, because the cars were lighter, and 7 decades of parking have cracked them into panels that rock. Patching buys a season, because the crack comes back through the patch the first time a car sits on the loose piece.
So we take the old slab out rather than pour over it. The pieces are broken and hauled and the subgrade is compacted, then 4 inches of Class 2 base goes down and is plate-compacted. The new slab is poured 4 inches thick with number 3 steel on an 18-inch grid, and 6 inches at the apron where the car turns off the street. Where the new work meets a slab that stays, at the garage door or the porch, we dowel the joint so the 2 pieces move as one.
Vincent went up in one push after the war, so its concrete is one age and fails one way. Driveways poured thin in the 1950s, garage floors that dust, walks lifted by old trees. The work is replacement, on lots too close for a mixer to reach.
A Vincent driveway is a 1950s slab poured thin for lighter cars, and after 70 years the panels rock. We break it out, compact 4 inches of base and pour 4 inches with number 3 steel, 6 at the apron, and file the county permit for the apron, because that strip is public right-of-way.
Vincent back yards are small and reached through a side gate under 5 feet wide, so the concrete is barrowed in from the truck at the curb. We pour 4 inches on compacted base, joint it every 10 feet and set the fall a quarter inch per foot away from the house, because the valley floor is flat and water needs telling where to go.
A stamped patio is the finish Vincent owners ask for when the front of the house has been redone and the back is still a bare slab. We cast ashlar or flagstone into a 4 inch slab, color it integrally and seal it in 2 coats, so it reads as stone with none of the joints that let a paver patio shift.
The parkway trees in Vincent are as old as the houses, and their roots have lifted the walks. We saw-cut the raised panel, take it out, cut the root back and pour a new panel doweled into its neighbors so the joint stays flush. The walk is county right-of-way, so we file with the county before we cut.
Garage floors in Vincent dust and crack because they were poured thin in the 1950s with no vapor barrier under them. We break out the old slab, lay a 10 mil barrier on compacted base and pour 4 inches troweled flat, which is the slab an epoxy or a tile floor needs and the old one never was.
A plain gray slab in a Vincent yard is too hot to cross barefoot by early afternoon in a valley summer that passes 100 degrees. We pour a light integral color with a salt or broom finish, which stays cooler underfoot and shows the dust less than a dark stamped surface does.
Vincent is flat, so a wall here is a low one at a planter or a garden step rather than a hillside hold. We foot it 18 inches into compacted ground, drain behind the stem with gravel and a perforated pipe, and take anything over 4 feet to Los Angeles County for a permit before we dig.
A garage conversion in Vincent is the way a postwar house gains a room, and the old garage slab is not a floor anyone should live on. We break it out, lay a 10 mil vapor barrier on compacted base and pour a new slab troweled flat enough for tile, with the joints laid out to sit under the walls.
Vincent is unincorporated. It sits between Covina and West Covina but is in neither city, so a permit for a wall or a right-of-way apron goes to Los Angeles County Public Works, Building and Safety, and not to a city hall. We file with the county, and it matters, because a homeowner who takes the plan to Covina is sent away and loses the week. Our yard is in Ontario, a straight run west on Interstate 10 to the Azusa Avenue exit.
The streets either side of Vincent Avenue were laid out on a grid with the houses close together, so side yards run under 5 feet and a mixer stops at the curb. Most back patios and garage floors here are barrowed in through a gate, which is a crew-hours question rather than a materials one. The front driveways are short and straight, which is the easy part, and the apron at the street is county right-of-way, which is the part that needs a permit.
The valley floor here is flat enough that water has nowhere obvious to go, and the old driveways were poured with no fall, so they pond after a storm. Every slab we pour in Vincent is graded a quarter inch per foot toward the street, and where a driveway runs downhill to a garage we set a trench drain across the door. Summers on the valley floor pass 100 degrees, so from July to September the pour starts at 6 in the morning and is covered by noon.
Four stages and one figure, written on the day of the visit. The county permit is the stage that takes the longest, so it is filed first and the crew is booked to the inspection rather than the other way round.
Victor Salgado measures the slab, checks the fall to the street, photographs the side gate and writes the figure before he leaves the driveway.
Where the apron or a wall needs one, we file with Los Angeles County Public Works, Building and Safety, and book the inspection.
The 1950s slab is broken and hauled, the subgrade is compacted and 4 inches of Class 2 base is laid and plate-compacted.
Poured 4 inches thick with steel, joints cut the next day and the slab covered. Walk on it after 24 hours, park on it after 7 days.
Call or send the form and we will get back to you within 1 business day to set the visit. Victor Salgado measures the slab in Vincent and writes the figure on the spot, and neither the visit nor the figure costs anything.
Reviews
Our own reviews, left on Google and Facebook by homeowners in the towns we cover, Vincent among them. The work behind them is the work on this page.
“Our place off Euclid is from the 1920s and the drive still ran back to the alley. They replaced 400 square feet at 5 inches, matched the fall to the alley apron and cut the joints the same day. Victor was there from start to finish.”
“We built an ADU in the back garden and needed the slab done properly. They over-excavated the old dairy ground, brought in engineered fill and poured to the soil report. It passed inspection first time, which is not what I expected.”
“The warehouse yard on Jurupa Street was breaking up under the forklifts and we could not shut down to fix it. Ontario Concrete Pro poured 2,800 square feet at 6 inches over two weekends so we never stopped shipping. A year on the joints are still tight.”
What Vincent homeowners ask before they book, covering what moves the estimate on a small postwar lot, which county office takes the permit, and how long a driveway is out of use.
The tear-out, then the access. Every Vincent driveway we pour replaces one from the 1950s, so the job starts with a breaker and a dump run. After that it is area, thickness and whether the concrete can be chuted from the truck or has to be barrowed through a side gate. Every estimate is measured and written on site, so the number comes off a tape measure and not a guess.
Los Angeles County. Vincent is unincorporated, so a permit for a retaining wall over 4 feet, a footing that carries a roof, or a new apron in the public right-of-way is filed with Los Angeles County Public Works, Building and Safety, not with Covina or West Covina. Flatwork at grade in your own yard needs none. We file it and meet the county inspector.
About 10 days until you park on it. Breaking out the old slab and compacting the base takes 1 day, forming and pouring takes 1 or 2 more, and the concrete then needs 24 hours before foot traffic and 7 days before a car. Add the county's time on the permit where the apron is replaced, which we file before the crew is booked.
Not on its own. The valley floor is sandy alluvium that drains and does not swell, so movement is rarely the cause. Vincent slabs crack because they were poured thin in the 1950s and have carried cars ever since. A new 4 inch slab with steel on an 18-inch grid over compacted base does not carry the same fault.
Just over 20 miles. Our yard is in Ontario, and Vincent is a straight run west on Interstate 10 to Azusa Avenue, so the crew is on site before 7 in the morning. We are in Covina and the towns beside it most weeks, and Vincent is on the same route, so a job here is scheduled like a local one rather than a trip.
Yes, the ones on the same road. Covina is next door to the east and Glendora is beyond it, San Dimas is up the 57 and Walnut is south over the hills, all covered from the one yard in Ontario. Each has its own page, and because Vincent's edges are city lines, the page for the town next door may describe your street too.
Vincent has Covina on one side and West Covina on the other, with Glendora, San Dimas and Walnut a few miles beyond, all reached on the same run from Ontario. If your street is on a city line, the page for the town next door is worth reading as well.
