Concrete Slabs
Slab work is base preparation, thickness, steel, joints, and finish. Every one of those is a decision and every one of them shows up years later. This is the page for a slab that is not already a driveway or a patio.
Talk to us about the job
How the job runs
Walk it with you
A site visit before anything else, so the scope is built on what is actually there.
Tell you what it needs
Including when the honest answer is the smaller job.
Fix what is under it
Grade and compaction done properly, because that is what the slab rides on.
Build and pour
Forms, steel, placement, consolidation, finish. Each one in order and none of them rushed.
What this job actually needs
Base, then steel, then concrete
A slab is the visible finish on a job that is mostly earthwork. Subgrade corrected, base placed in controlled lifts and compacted, steel lifted on chairs into the upper portion where tension happens, then concrete placed and consolidated. Each step is checkable and each one shows up years later.
Vapor control where it matters
Any slab inside a building, or anything getting a floor covering or a coating later, needs a vapor barrier under it. Moisture coming up through a slab will lift flooring and delaminate coatings, and retrofitting the barrier is not possible.
Thickness and reinforcement
Both come off the load. Foot traffic, vehicles, equipment and racking are all different, and the reinforcement schedule changes with them. We would rather build it right than build it thin and be back.
Finish for the use
A slab that will be coated later gets finished differently from one that stays exposed. A slab that gets wet needs texture. Telling us what the floor is for changes how it gets finished.
What decides whether it lasts
Concrete is judged on the surface and it fails from underneath. The base, the steel, the joints and the cure are the whole job. A slab that was poured on bad ground will tell you so, usually in the third or fourth year.
Why fourth generation matters here
32 years on the tools means most of these problems have already been seen once. Reading a slab before quoting it is the part you cannot learn from a book, and it is the difference between a repair that holds and one that comes back.
What Southern California ground does to concrete slabs
Drainage on a flat lot
Valley lots are often close to level, which makes slope hard to find and easy to get wrong. Low points, cross-fall and where water actually leaves the property get worked out before the pour, because once the concrete is down the drainage is permanent.
What the ground does here
The inland valleys run on expansive clay. It takes on water and swells, then dries out and shrinks, and it does that cycle every year. A slab poured on untreated clay rides that movement until something gives, which is why base preparation and reinforcement are the design rather than an upgrade. Where a soils report exists we build to it; where there is none, what we find during excavation tells us what the ground is going to do.
Summer pours
Triple digit afternoons change how concrete behaves. It stiffens before it can be finished properly, the surface skins over while the body underneath is still soft, and water leaves the slab faster than the cement can use it. Valley pours start early, the mix gets adjusted for the heat, and curing is treated as an active step instead of something that happens on its own.
Irrigation against the slab
Almost every valley property waters something, and sprinklers running along a slab edge keep the base saturated year round. In expansive soil that is a slow way to undermine your own driveway. Where the water lands is worth looking at before blaming the concrete.
How concrete fails, and why
Thin slab cracking under vehicles
A four inch slab under a work truck or an RV will crack in the wheel path. Thickness has to come off the actual load, not off what is typical.
Joints in the wrong place
Joints spaced too far apart let the slab crack between them. The rule of thumb is roughly two to three feet of spacing per inch of thickness.
Surface loss at door thresholds
Water runs off a roof or a door and lands in the same line every time. Concentrated water wears concrete, and a drip line is a real design consideration.
Reinforcement too low
Steel sitting on the subgrade is doing nothing. It has to be lifted on chairs into the upper portion of the slab where tension actually occurs.
How a job runs
The walkthrough
Somebody comes out and looks. That visit decides the scope, and it is also when you should ask everything, because the answers get cheaper before the concrete is ordered.
What you decide
Finish, color, joint layout and edge detail are choices. We will make recommendations based on where the slab is and what it has to do.
Knowing when to start floating is the part you cannot learn from a book.On finishing
What we decide
Thickness, base, steel and mix come off the load and the soil. Those are not preference items and we will not build them thin to win a job.

You get told how to look after it: when to seal, what not to put on it, and what normal looks like in the first year.

Straight answers
How much does concrete cost?
It depends on access, thickness, base condition and finish, which is why we walk the job before giving a number. We will not quote a driveway off a photograph.
How long before I can drive on a new slab?
Concrete takes most of its strength in the first week and keeps gaining for a month. Foot traffic is usually fine after a day or two. Vehicles wait longer, and we will give you the actual number for your pour, because thickness and weather both change it.
Do you fix the base or just pour over it?
We fix the base. Pouring new concrete on ground that already failed once is how you get the same crack in the same place. If the base is the problem, that is the work.
Can you match my existing concrete?
Usually close, rarely exact. Concrete changes color as it ages, so a new pour next to a ten year old slab will read newer for a while. We match thickness, finish and joint pattern so it looks intentional.
Will it crack?
Yes, eventually, and that is the material rather than a defect. The job is deciding where. Control joints put the crack on a line we cut instead of one it picks. A slab with no cracking plan will still crack, just somewhere you did not want.
