Concrete and Design in Moraga, CA
Almost everyone has seen a concrete patio or driveway that cracked, heaved, or pitted within a few years, and almost every one of those failures traces back to what happened before the pour, not to the concrete itself. A slab is only as good as the base beneath it, the reinforcement inside it, and the joints cut into it to control where it cracks. Done right, concrete and design in Moraga, CA, delivers a surface that stays flat, sheds water, and looks intentional for decades; done carelessly, it becomes the eyesore you eventually pay to tear out and replace.
The East Bay hills are beautiful to build on and genuinely tough to build right. The expansive clay soils common across Contra Costa County swell when wet and shrink when dry, heaving and cracking any slab that was not poured over a properly prepared, compacted base. Sloped Lamorinda lots add drainage and grading challenges that flat ground never poses. Quality concrete work for Moraga homes has to start underground, with the base and the drainage, long before anyone smooths the surface everyone sees.
At Aloha Concrete and Design, we have spent more than 20 years building patios, driveways, walkways, and retaining walls across the East Bay, and we treat the dirt work with the same care as the finish. We are a licensed concrete contractor with an A+ rating from the Better Business Bureau, and we handle each project from the design through the final cure. Picture the outdoor space you actually want, then call us and we will show you how to build it to last.
About Moraga, CA
Moraga is a town of 16,870 residents, recorded in the 2020 census, set in the rolling hills of Contra Costa County in the East Bay. Incorporated in 1974, it takes its name from Joaquín Moraga of the prominent Californio family whose land grant once covered this valley, a history the town has worked to preserve.
Education and open space define the place. Saint Mary's College of California sits at the heart of town, the Moraga School District serves local families, and the Moraga Library and Joaquin Moraga Intermediate School anchor community life. The Moraga Adobe survives as a tangible link to the area's nineteenth-century roots.
Geography shapes daily life here. Moraga spreads through Rheem Valley and the surrounding hills, with the Lafayette-Moraga Regional Trail winding through the greenery as part of the wider Lamorinda area. It is a community of hillside homes and generous lots, the kind of place where a well-built patio or driveway is part of how a property is meant to be enjoyed.
Why East Bay Clay Soil Cracks Concrete That Was Poured Wrong
On expansive clay, concrete cracks because the ground underneath it moves. The clay soils across the East Bay swell as they absorb winter rain, then shrink and pull away as they dry through summer, and a slab poured directly on that untreated ground rides the heave like a raft. The fix is a stable foundation: a properly compacted aggregate base, usually four to six inches, that spreads the load and buffers the soil.
What goes into the slab matters just as much. A standard residential slab runs about four inches thick, while a driveway wants five or more, with steel reinforcement, rebar, or wire mesh, to hold it together if the ground shifts. Control joints, cut at regular intervals, give the concrete a planned place to crack instead of cracking where it shows.
Water is the last piece. A slab needs a slight slope, roughly one to two percent, to shed rain away from the foundation rather than pooling against it. We build all of this from the ground up, because a beautiful finish over a bad base is just a slower failure.

Stamped, Broom, or Exposed Aggregate: Choosing a Concrete Finish That Fits
Plain gray concrete is only the starting point; the finish you choose changes how a surface looks, performs, and holds up underfoot. A broom finish, where the surface is lightly textured with a broom before it sets, is the practical workhorse: affordable, slip-resistant, and right for most driveways and walkways. A smooth trowel finish looks sleek but becomes slick when wet, making it better suited for indoors than for an outdoor patio.
Decorative finishes open up the design. Stamped concrete presses pattern and texture into the fresh surface to mimic stone, slate, or brick at a fraction of the upkeep, and it takes integral color to match a home's palette. Exposed aggregate, where the top layer is washed away to reveal the stone within, gives a durable, naturally textured surface with excellent traction, which suits sloped Lamorinda driveways especially well.
Each finish carries its own maintenance and sealing needs, and the right one depends on the use, the slope, and the look you are after. Aloha Concrete and Design walks you through the trade-offs so the surface fits the space rather than fighting it.
Why Moraga, CA Residents Trust Aloha Concrete and Design
Concrete is unforgiving of shortcuts because every mistake is literally set in stone, which is why two decades of doing it right is the reference that matters most. Across more than 20 years in the East Bay, we have learned how this clay behaves, how to prep a base that outlasts the seasons, and how to pour and finish so a surface still looks sharp years later. That experience lives in the parts of the job you never see.
We are a licensed California contractor, and our A+ rating with the Better Business Bureau reflects how we run projects: clear communication, an honest scope, and clean work from the first stakeholder to the final seal. We handle both the design and the build, so the patio or driveway you picture is the one that actually gets poured into place.
Most of all, we build the unseen parts as carefully as the visible ones, the base, the reinforcement, the joints, and the drainage that decide whether concrete lasts. That blend of long local experience, real credentials, and care across every phase is why homeowners across the area keep calling Aloha Concrete and Design.

Testimonials
June and his crew were very easy to work with. He was very communicative throughout the process. His price was very competitive but even more importantly he was able to take my initial design ideas and bring them to life! He removed a straight path and put in cement slab steps with an accent wall adding so much personality to our front yard. Aloha Concrete and Design are the best!
chris f.
We worked with June and his team to redo a crumbling 1500 square foot patio and he did a great job and was super easy to work with. I can't recommend Aloha Concrete enough for concrete work. His demo bid was 1/3 the others and his team knocked out the whole thing really quickly. Thanks Aloha!
Eric B.
We got our whole back yard renovated with Aloha Concrete and Design. Our retaining wall looks great and our Patio looks brand new after the overlay job, but my favorite part is our concrete fire pit. It was a good experience working with June, I would recommend it.

He completed the work right away and we are extremely happy with the outcome! We would recommend Aloha Concrete to anyone looking for quality work with a great stand up, genuinely nice guy/company!

Frequently Asked Questions
Why did my old concrete driveway crack and heave like that?
Usually, the base, East Bay clay, swells and shrinks seasonally, so a slab over untreated ground moves and cracks, which is why we build Moraga slabs over a compacted base.
How long does a new concrete driveway take to install?
Most concrete driveways take 3 to 5 days, covering base prep, pouring, finishing, and curing; we keep Moraga jobs moving while giving the slab the time it needs to cure.
What concrete finishes do you actually offer?
We offer broom, smooth trowel, stamped, and exposed aggregate finishes; each suits a different look and use, and we help Moraga homeowners match the finish to slope, traffic, and style.
Can you build a retaining wall on my sloped Moraga lot?
Yes, retaining walls are one of our core services; on Moraga's hillside lots we design walls that manage the slope, control erosion, and add usable, level space to the yard.
How soon can I walk or park on new concrete?
You can walk on new concrete after about 24 to 48 hours, but wait seven days before driving on a slab, since concrete keeps gaining strength after it looks set.
Is stamped concrete a good option for outdoors here?
Yes, stamped concrete mimics stone or brick with less upkeep, takes integral color, and holds up well outdoors in Moraga when it is sealed and given control joints and a base.
Are you licensed and insured for concrete work?
Yes, we are a licensed California contractor with an A+ Better Business Bureau rating, so your Moraga project is handled by a credentialed, fully accountable concrete company.
Do you handle the design, or do I need my own plan?
We handle design and construction; bring an idea or a blank slate, and we will design the patio, driveway, or walkway and build it, so one team carries the project.
