The loads on a South Gate drive have doubled and the slab has not. A drive laid in the 1930s for one car now carries three vehicles and turns a trailer, and the concrete was never built for it.
A slab breaks where the weight stops and turns. A pickup at 2 and a half tons parked on the same spot every night presses the base under it a little each time, and once the base has settled the slab spans a hollow and cracks across it. A trailer backed down the side to the rear lot turns on the slab edge, which has nothing beside it to hold it, and the corner goes. Here the drive is also the road to the rear unit, so it is loaded all day, and a patch on a thin slab fails inside a year.
So the drive is poured to the heaviest thing on it. Five inches under a pickup and 6 where a trailer turns, on 4 inches of rock compacted in lifts over the river sand, with number 4 steel on an 18-inch grid and the edge thickened to 12 inches down the side yard where the wheels ride. The panels are cut at 10 feet so the slab moves at the joint and not across it, and the run to the back is poured in one piece with the apron, since a step between slabs is where a drive fails first.
Lots in South Gate work for a living. A pickup, a trailer and a van park on the drive, a shop or a rear unit sits where the garage was, and the slab from street to back fence carries all of it, so it is poured to the truck and not the car.
A drive in South Gate runs from the apron to the back fence and carries every vehicle in the household, so we pour it at 5 inches for a pickup and 6 where a trailer turns, on 4 inches of compacted rock with steel at 18 inches, in one piece from the street to the rear unit.
Patios in South Gate sit behind the house and beside the rear unit, in whatever ground the drive has left. We pour them at 4 inches on compacted rock, pitch them away from both buildings, joint them at 10 feet, and where the patio doubles as the tenant's walk we broom it coarse.
Stamped concrete in South Gate is a front court where the lawn was, since a paved front yard is parking and a stamped one reads as a courtyard rather than a lot. We cast a stone pattern into a 4 inch slab thick enough to park on, seal it in 2 coats, and leave the apron plain.
The public walk along a South Gate street is the city's and the strip from the walk to the porch is yours, and the join between them has usually stepped. We replace the private panel on compacted rock, dowel it to the city's, and file the approach where it crosses the line.
Garages in South Gate are workshops and storage as often as parking, at the back of a lot with the drive running to the door. The old floor is 3 inches on dirt and cracked. We break it out, compact 4 inches of rock and pour 5 inches with steel, troweled flat, pitched to the door.
Exposed aggregate suits a South Gate front yard that has to park a car and still look like a yard, since washed stone hides tire marks and drips that a plain gray slab shows. We pour it at 4 inches with a smooth banded border and seal it once the cure is finished.
South Gate is flat, so a wall here is a low one, holding a raised bed or a step between a lot and the one next door rather than a hill. We foot it 18 inches into the compacted sand, drain behind the stem, and file it at City Hall only when it stands over 4 feet, which few do.
The interior slab in South Gate is the floor of a rear unit or a converted garage, poured for someone to live on. We pour it at 4 inches over a 10 mil barrier on compacted rock, thicken the edge to carry the walls, trowel it flat for tile, and file it as a foundation.
We come to South Gate from Torrance by the 405 and the 710, off at Firestone Boulevard, about 15 miles and forty minutes, so a job here is booked as a full day and the truck leaves loaded for it. The city is its own, in Los Angeles County, and permits go to the Building and Safety Division at City Hall on California Avenue. A drive approach, a slab under a unit, a wall over 4 feet and a shop apron are filed there, and the inspector checks the base and the steel before the pour.
The lots between Firestone Boulevard and Tweedy Boulevard are the busiest, narrow and deep, with the house at the front and a unit or a shop at the back, and the drive down the side is the one route to it. Tweedy Boulevard itself is shopfronts, the Tweedy Mile, where the concrete is the apron between the walk and the door and the bays behind. Firestone Boulevard carries the larger lots and the Azalea center at Atlantic Avenue, and the streets toward Hollydale are the same small houses.
The ground is the plain the Los Angeles River built, sand and silt that compacts well and drains, so a slab here rarely heaves and a failure is a base or a load failure, not a soil one. That makes the work simpler than it is on the Riviera or the peninsula, and it is why we pour in South Gate on any dry day of the year. Summer pours start at first light, since a narrow drive between two houses is in full sun by nine, and winter pours wait for a dry night as well as a dry day.
Four steps and one written figure, measured on the lot. On a lot with a rear unit the drive is the tenant's route in and out, so the dates are agreed with everyone living there before a slab is cut.
Kenji Okamoto measures the drive, asks what parks and turns on it, checks the sand at the side yard and writes the estimate on site.
The old strips or slab come out in a day, the sand is compacted, and 4 inches of rock goes in and is plate-compacted, thicker at the edges.
The approach, a unit slab or a wall is filed with Building and Safety, and we meet the inspector. A patio inside the lot needs no permit.
5 or 6 inches on steel, poured in one piece to the back, joints cut that day. Feet after 24 hours, the pickup after 7 days, a trailer after 28.
Call or send the form and we reply within 1 business day with a day. Tell us what parks on the drive and whether there is a unit at the back, since those two things set the thickness, and the figure is written at the lot before we go.
Reviews
Our own reviews, left on Google, Facebook and the BBB by homeowners across the South Bay and the towns along the 710. The rear-lot drives among them read the way the work above is described.
“The garage slab in our 1955 house had heaved and the door would not close. They broke it out in a morning, found no base under it, compacted 4 inches of rock, poured 440 square feet at 5 inches and troweled it smooth. The estimate was written in our driveway and the invoice matched it.”
“We built an ADU and Hawthorne Torrance Concrete did the slab. They set the forms to the plans, the City inspector passed the steel first time, and the pour went in before eight in the morning. 620 square feet, edges thickened to 12 inches, and the framers were on it a week later.”
“Our slope in the Riviera crept onto the patio every winter. They dug footings 30 inches into the clay, poured a 42-foot wall with weep holes and a drain behind it, and backfilled with gravel. Kenji Okamoto came back after the first rains to check it. Dry, straight, and it has not moved.”
What people in South Gate ask before a pour, on cost, permits, how far we come, the river sand under the lot, how long the drive is out of use for the family and the tenant, and which towns around it we cover.
Its thickness, and thickness is set by what parks on it. A drive for cars goes in at 4 inches, a pickup or a van takes 5 and a trailer 6, and each inch is a quarter more concrete and a stiffer steel grid. After that it is length, since a South Gate drive runs the depth of the lot to the rear unit, and then the tear-out. All of it is measured at the lot and written there.
For the approach across the public walk, yes, and for a slab under a rear unit, a wall over 4 feet or an apron on a shop frontage. Those are filed with the Building and Safety Division at City Hall on California Avenue, and the inspector sees the base and the steel before the pour. A patio, a walk or a drive inside your own lot line needs none. We file and meet the inspector.
About 15 miles, by the 405 and the 710 to Firestone Boulevard, and about forty minutes at the times a crew travels. It is the northeast end of the towns we cover, so the day is booked whole and the truck is loaded for it. The call back is within 1 business day as everywhere, and the estimate visit is usually inside the week.
Yes, among the easiest we work on. It is the sand and silt the Los Angeles River spread across the plain, and it compacts and drains, so a slab on it does not heave with the season the way one on the Palos Verdes clay does. What it will do is settle under a wheel that stops on the same spot every night, which is a base problem, and the rock under the slab is what answers it.
Two to three days on site and then 7 before a car goes on it, so about ten days in all, and everyone parks on the street. We tell the tenant the dates, keep a walking route down the far side of the house open through the work, and pour the whole run in one morning so the back of the lot is not cut off twice. A trailer waits 28 days.
Lynwood and Paramount on the 710, Compton and Carson down toward the 405, Florence-Graham across the northern line and Signal Hill at the bottom of the 710. Downey and Huntington Park are not on our list, so a street on the east or the north edge of South Gate may be one we cover on one side and not the other, and we say which on the phone.
South Gate borders Lynwood, Paramount and Florence-Graham, all on our list, and the freeway runs on to Compton, Carson and Signal Hill, which are too. Downey and Huntington Park are not covered, so on a street along those lines, say which side you are on.
