How thick should my concrete slab be?

For light use like a shed floor or walkway, 4 inches is sufficient. For garages and driveways where vehicles park, we recommend 6 inches. Heavy equipment or commercial applications may need 8 inches or more. We evaluate your specific use case and soil conditions to recommend the right thickness for your project.

Do I need a permit for a concrete slab?

It depends on the size and purpose. Small slabs under 200 square feet for landscaping or storage often do not require permits. Larger slabs, anything attached to a structure, or slabs for permanent buildings usually need permits. We help you determine permit requirements and can handle the application process for you.

Can you pour concrete in cold or wet weather?

Yes, but with precautions. Cold weather requires special mix designs and curing blankets to protect the concrete. We avoid pouring in rain or when rain is expected within 24 hours. Daly City's mild climate usually allows year-round concrete work, though we schedule carefully during winter months to ensure optimal curing conditions.

Concrete Slabs & Flatwork

Professional concrete slabs for sheds, garages, workshops, and any flat surface you need

Professional concrete flatwork and slab installation in Daly City

When you need a solid, level surface for a shed, garage, workshop, or equipment pad, concrete slabs deliver unmatched durability. At CircleRock Daly Concrete Works, we pour professional concrete slabs in Daly City for residential and commercial properties. Our slabs stay level, resist cracking, and provide decades of reliable service.

What Is Concrete Flatwork?

Flatwork is the industry term for any horizontal concrete surface. This includes driveways, patios, sidewalks, and slabs. When people talk about concrete slabs specifically, they usually mean a flat surface designed to support structures or equipment rather than decorative spaces.

The requirements for a slab depend on what sits on top of it. A storage shed needs less reinforcement than a workshop with heavy machinery. We customize the thickness, steel reinforcement, and base preparation based on your specific needs.

Where We Pour Concrete Slabs

We install concrete slabs for many purposes around Daly City properties:

Shed foundations: Level base for storage sheds and outbuildings
Garage floors: Durable surface that handles vehicle weight and oil stains
Workshop slabs: Strong foundation for tools, workbenches, and equipment
Equipment pads: Stable platforms for HVAC units, generators, and pool equipment
RV parking pads: Extra parking for boats, RVs, and trailers
Basketball courts: Smooth, level surface for sports and recreation

Each application has different requirements. We talk through how you plan to use the space and design a slab that meets those needs without overbuilding.

How We Build Slabs That Last

The quality of concrete work happens below the surface. Before we pour any concrete, we focus on site preparation. We excavate to the proper depth, grade for drainage, and compact the subgrade. Then we install a gravel base that provides stability and prevents settling.

Reinforcement and Thickness

Standard residential slabs are 4 inches thick with wire mesh or rebar reinforcement. If you plan to park vehicles or store heavy equipment, we increase the thickness to 6 inches and use heavier steel. This prevents cracking and ensures the slab can handle the weight without issues.

We also cut control joints into the concrete to direct cracking where we want it. These joints are planned features that help the concrete expand and contract without random cracking.

Drainage and Site Grading

Proper drainage is critical in Daly City. We grade your slab with a slight slope so water runs off rather than pooling. This is especially important for garage floors and equipment pads where standing water causes problems. We also consider how the slab affects drainage around the rest of your property.

Many homeowners need both a new slab and related work like walkways to connect buildings or adjacent patio areas. We can handle all your concrete needs in one project, which saves time and creates a coordinated look.

Timeline and What to Expect

Most slab projects take 2 to 4 days from start to finish. Day one involves site prep and forming. Day two we pour and finish the concrete. Days three and four are for curing. You can walk on the slab after 24 hours, but wait at least a week before placing heavy loads on it.

Cost depends on the size and thickness of the slab, plus any special requirements like extra reinforcement or site access challenges. We provide detailed quotes upfront so there are no surprises. Most residential slabs range from $6 to $12 per square foot depending on these factors.
