ADU Concrete
ADU work happens in a back yard with tight access, an existing house to protect, and its own permit and inspection path. The concrete is simple. Getting a truck to it usually is not.
Talk to us about the job
How the job runs
Start with a site visit
No number gets quoted before somebody stands on the job. Soil, slope, access and drainage change the work more than square footage does.
Tell you straight
We are direct about what we find. That includes telling you when a cheaper fix is the right one, and when a slab is past saving.
Prepare what is underneath
Excavate to grade, deal with anything soft, and build compacted base. Almost every failure we get called to started here.
Place and finish
Forms that hold their line, steel placed to the drawing, concrete consolidated, and finishing timed to the slab. Thirty two years in the trade is largely knowing when to start.
What this job actually needs
Sequence and inspections
Footings, stem walls, slab, then flatwork at the end, with inspections between stages. Each one has to clear before the next starts, and a missed window holds up every trade behind the concrete.
Coordination with the build
Plumbing, electrical and any under-slab work all have to be in and inspected before the pour. That coordination is most of what makes new construction concrete run smoothly or badly.
Sloped and difficult sites
Hillside work means stepped footings, retaining, drainage with real consequences, and access planning for trucks and equipment. In Southern California that is common rather than exceptional.
Building to the soils report
Where a soils report exists it governs footing depth, reinforcement and sometimes soil treatment. It is the document that tells us what the ground will actually do.
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 adu concrete
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.
Older flatwork around here
A lot of valley concrete was poured thin, with light reinforcement, on a base that was never properly compacted. When it fails it is usually reporting on the ground rather than on the mix, and that is the difference between a repair that holds and one that comes back in a year.
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.
How concrete fails, and why
Failure at a cold joint
Where one pour met another and was not detailed, the two never bonded and the line opens. Planned cold joints are fine; accidental ones are a leak path and a crack.
Curling at the edges
Slab edges lifting off the base happens when the top dries faster than the bottom. It shows as a hollow sound near joints and it is a curing and moisture-gradient issue.
Scaling in freeze zones
Surface peeling in sheets, common at elevation and in the high desert, is freeze damage in concrete that was not air entrained or was sealed too late.
Blisters
Raised bubbles under a finished surface mean the top was closed while air or water was still coming up. They break under traffic and leave holes.
How a job runs
The soil question
In expansive clay the soil drives the design. If there is a soils report we build to it; if not, what we find during excavation informs the base work.
Drainage
Where water goes gets decided before the pour, because afterward it is permanent. That sometimes means changing the plan to fix a problem you already had.
A repair aimed at the wrong cause is money spent twice.On repair work
Joint layout
Joints are planned on paper and cut on time. Where they land is partly structural and partly how the finished slab reads.
Maintenance
Concrete is low maintenance, not no maintenance. Sealing and joint upkeep are the two things worth doing.
Other new construction work
New Construction Concrete
Concrete from footings through flatwork on a new build.
Custom Home Concrete
One-off houses where nothing is a standard detail.
Multi-Family Concrete
Repeating foundations and flatwork at scale.
Hillside Concrete
Sloped sites, stepped footings, and retained grade.
Straight answers
Do you do ADU foundations?
Yes. The concrete is usually simple and the access usually is not, so we plan how a truck or a pump reaches a back yard before quoting it.
What about the soils report?
If there is one, we build to it. It tells us bearing capacity and how the soil behaves, which drives footing depth and reinforcement.
Can you work on a sloped lot?
Yes. Hillside work means stepped footings, retaining, and drainage that has real consequences. It is common in Southern California and it is not standard flatwork.
Who arranges the inspections?
We schedule the concrete inspections into the pour sequence. On a permitted build the general contractor and we coordinate so nothing waits.
How does concrete fit the build schedule?
Footings, stem walls, slab, then flatwork at the end, with inspections between. Missing a window holds up every trade behind you, so the sequence gets planned with the builder.
