Concrete Contractor in West Carson, CA - Driveways and Patios That Drain Right
H&J Gardena Concrete Contractors pours driveways, patios, walks and slabs in West Carson, with the base dug out and packed and the water sent away from your house.

Concrete contractor for West Carson homes
West Carson is unincorporated, so the County of Los Angeles does the job a city would. Most homes here carry a Torrance ZIP, but that mailing address doesn't put you inside Torrance, so any permit your concrete job needs goes through LA County Public Works. Its permit guide lists repairs, replacements, new construction, additions, alterations, pools and grading, and your local office can tell you what your own project needs. We check with the county for your address too, and when a job needs a permit, we pull it and line up the inspections before we pour.
We're a concrete contractor based in Gardena, CA, and we pour the same flatwork, the driveways, patios and walks that sit right on the ground, in Carson and Del Aire. Your price turns on the size and thickness of the slab, whether an old one has to come out, how much base work the ground needs and the finish you pick. The schedule turns on any permit and inspection, and on curing, the days new concrete needs to harden before you drive on it, so plan on parking somewhere else for a stretch. I walk the job, measure it and put the work in writing, so you get your own number. Most cracked slabs we tear out failed underneath, on a base that was raked flat instead of dug out and packed, and that's where your job starts.
What we pour in West Carson
Concrete driveway building
Most driveways here take daily car weight, so we dig out the soft dirt, pack the base and pitch the slab toward the street, not the garage.
Concrete patio construction
A patio has to shed water away from your back door, so we set the slope first and cut control joints, grooves that tell cracks where to go.
Stamped concrete services
Stamped concrete gives a walk or patio the look of stone or brick. We press the pattern while the slab is still soft, so timing the pour matters.
Concrete sidewalk building
If the walk to your door has lifted into a trip edge, we tear out the bad sections and pour new ones on a packed base.
Garage floor concrete
An oil-stained, cracked garage floor usually gets broken out and replaced. We check the base underneath and pour the new floor so water runs out the door.
Decorative concrete
Colored concrete and scored patterns let a plain slab match the house. We'll show you which finishes stay easy to clean and safe underfoot.
Concrete retaining walls
Where a yard steps down, we build retaining walls with drainage behind them, because water trapped back there is what pushes walls over.
Concrete floor installation
For a workshop, a room addition or a converted garage, we pour floors flat and level, with a moisture barrier underneath when the space will be finished.
Concrete pool decks
A pool deck has to drain away from the water and stay safe for bare feet, so we slope it carefully and give it a textured, non-slip finish.
Concrete steps construction
Front steps that cracked, crumbled at the edges or pulled away from the porch get torn out and re-formed, with even step heights so nobody catches a toe.
Slab foundation building
For a new garage or an addition, we pour the slab on a packed base with rebar inside, steel bars that keep cracks from pulling apart.
Foundation installation
When you're adding onto your house, the new foundation has to sit level with the old one, so we dig, form and pour it to the plans.
Concrete parking lot building
Small property owners with apartments or shops get concrete parking areas poured thick enough for steady traffic, sloped to the drains, with joints cut on time.
Concrete footings
Footings carry the weight of a wall, a patio cover or a post, so we dig them as deep as the plans call for.
Foundation raising
When part of a house settles, doors stick and cracks open, so we find out why it sank before we lift anything.
Concrete cutting
We saw-cut openings for a drain line or a wider driveway, so we take out only what has to go and leave the rest of the slab whole.
What signs mean your West Carson concrete needs work?
Concrete is hard to undo, so a small sign caught early on a West Carson driveway or patio usually costs less to deal with than a slab that's failed.
- Cracks that keep getting wider
- Slab sinking near the garage
- Water pooling after you hose it
- Edges lifted into a trip
- Surface chipping or turning to dust
- Water running toward the house
If you're seeing one of these, call or send the form and I'll come out, look at it and tell you plainly what's causing it.
Can you patch it, or does it need replacing?
On most West Carson driveways and patios, the choice comes down to what's under the slab, because a sound base can carry a repair and a failed one takes any patch down with it.
When patching is enough
If the cracks are narrow, the slab is still level and water runs off the way it should, the base is doing its job. We can cut out a bad section or fix a lifted edge and leave the rest alone.
When it's time to replace
If the slab has sunk, tilts toward your house or cracks open again after every patch, the subgrade, the dirt it sits on, has usually moved. Then we tear it out, dig down to firm ground, pack a new base and pour fresh.
What concrete in West Carson has to handle
I've run this business out of Gardena since 2017, and what I care about most is the part you can't see once it's poured, like the base, the drainage and the joints.
Base first, finish second
When money's tight, we keep the packed base and go plainer on the finish, because the base decides how long it lasts.
Water sent away from you
We check where the water runs before we form anything, so the new slab falls toward the street, not your foundation.
Joints cut on time
Concrete cracks, so we cut joints on time and cracks usually follow lines we chose, not the middle of your slab.
Licensed and insured in California
The state contractor board requires a license for work that needs a permit or runs $1,000 or more, and we're fully licensed and insured.
