Concrete Slab & Foundation Work

We pour and finish concrete slabs and foundations for homes, garages, sheds, and commercial structures throughout Hayward, CA.

Why Getting the Foundation Right Matters

Everything you build sits on top of a slab or foundation. If that base is weak, poorly prepped, or improperly cured, the problems show up down the line: cracking, settling, moisture intrusion, and structural instability. By the time you notice the signs, fixing it costs far more than doing it right from the start.

We take foundation work seriously because we understand what is at stake. Whether you are building a new home addition, a detached garage, a workshop, a storage shed, or a commercial structure in Hayward, CA, the slab needs to be engineered to handle the load, prepared correctly, reinforced properly, and cured at the right rate. Cutting any corner on that list creates a problem that you may not see for years.

Our team has experience with a wide range of slab and foundation projects, from small residential utility slabs to large commercial pours. We work from the plans your architect or engineer provides, or we can help you figure out the right specs for simpler residential projects based on your intended use and load requirements.

The Types of Slab Work We Handle

Not every slab is the same. The design, thickness, reinforcement, and prep work vary based on what is being built on top of it. Here is a breakdown of the most common slab and foundation projects we take on.

Residential Garage Slabs

A garage slab needs to handle vehicle weight, oil spills, and daily use. We typically pour at 4 to 6 inches thick with rebar reinforcement and a smooth or broom-finished surface. We also install expansion joints and ensure proper drainage slope.

Shed and Workshop Slabs

For utility structures, a 4-inch slab with wire mesh is usually sufficient unless you are storing heavy equipment. We handle the grading and compaction so the slab stays level and does not settle unevenly under the structure.

Home Addition Foundations

Room additions, sunrooms, and accessory dwelling units (ADUs) require a foundation that ties properly into the existing structure. We coordinate with your contractor and follow the engineered plans to make sure the pour meets all code requirements in Hayward, CA.

Commercial Slabs

Warehouse floors, retail slabs, loading areas, and equipment pads require thicker concrete, heavier reinforcement, and often a specialty finish. We handle large commercial pours with the right crew and equipment to get the job done on schedule.

Utility and Equipment Pads

HVAC units, generators, pool equipment, and outdoor appliances need a level, stable pad. These are smaller pours but they still need to be done correctly so the equipment stays level and vibration does not cause premature cracking.

Replacement Slabs

If an existing slab has failed due to poor installation, tree root intrusion, or ground movement, we can demo and replace it. We assess the cause of the failure first so the new slab does not end up with the same problem.

What Our Slab Process Looks Like

From the first phone call to the finished pour, here is how we approach every slab and foundation job.

Site visit and review of your plans or project requirements.
Soil assessment and grading to ensure proper drainage and a stable base.
Excavation to the required depth based on slab thickness and frost line considerations.
Compacted gravel sub-base installation for drainage and load distribution.
Vapor barrier placement where moisture protection is needed.
Rebar or wire mesh layout based on load and structural requirements.
Forming of slab edges with lumber or steel forms.
Concrete delivery and controlled pour from the correct mix design.
Screeding, floating, and surface finishing to your specification.
Control and expansion joint installation.
Curing compound or wet curing to reach full design strength.

Permits and Inspections

Most foundation and slab projects in Hayward, CA require a building permit and at least one inspection before the concrete can be poured. We handle the permit application process and schedule the required inspections so nothing gets missed. You do not need to chase the city. We take care of it.

We also work closely with general contractors and owner-builders on larger projects. If you are managing a build and need a concrete sub who shows up on time and does clean work, give us a call. We understand how job site scheduling works and we do not hold up the rest of your crew.

Common Questions About Slab and Foundation Work

How thick does a foundation slab need to be?

The minimum thickness for a residential slab in California is typically 4 inches for lightly loaded structures. Garage slabs are generally 4 to 6 inches. Slabs for homes and load-bearing structures are usually 6 inches or more and include a thickened edge beam. The right thickness depends on the soil, the load, and the local building code. We review those factors with you before we spec the job.

How long does concrete take to reach full strength?

Concrete gains most of its strength in the first 28 days after the pour. At 7 days it typically reaches about 70 percent of its design strength, which is enough for light foot traffic. Framing and other trades can usually begin working on the slab within 7 to 14 days depending on the project requirements. We will coordinate the timeline with your general contractor if needed.

Do I need an engineer for a slab or foundation project?

For simple utility slabs like shed pads, most homeowners do not need a structural engineer. For anything that supports a building, including garages, home additions, ADUs, and commercial structures, an engineer-stamped plan is almost always required by Hayward building department before they will issue a permit. We can recommend engineers we have worked with if you need a referral, and we build to whatever specs the engineer provides.
