Concrete Slabs & Flatwork

When you need a solid, level surface for a shed, garage, workshop, or outdoor storage area, a concrete slab is the best foundation. Concrete flatwork refers to any horizontal concrete surface like slabs, floors, and pads. It provides a stable base that does not shift, settle, or rot like wood, and it handles heavy loads without breaking down.

We have been pouring concrete slabs and flatwork in Bloomington, IL since 2024, and we know how to build a slab that stays level for decades. Whether you are adding a detached garage, setting up a storage shed, or creating a workspace in your backyard, we will prepare the site correctly and pour a slab that meets your needs.

Common Uses for Concrete Slabs

Concrete slabs are the go-to foundation for any structure or equipment that needs a flat, solid base. They distribute weight evenly, prevent settling, and protect your investment from ground moisture. Here are some of the most common uses:

• Garage floors: A properly sloped slab keeps water from pooling and provides a smooth surface for vehicles.
• Shed pads: Elevates your storage shed off the ground and prevents floor rot and pest damage.
• Workshop foundations: Creates a level, stable workspace for tools, equipment, and projects.
• Equipment pads: Supports heavy machinery like HVAC units, generators, and hot tubs.
• Outdoor storage areas: Provides a clean, dry surface for firewood, lawn equipment, or recreational vehicles.

If you also need a driveway or walkway to connect to your new slab, we offer concrete driveway installation and sidewalk construction to complete your project.

How We Install Concrete Slabs

A concrete slab is only as good as the base underneath it. If the soil is not compacted properly or the base layer is too thin, the slab will settle unevenly and crack. We take the time to prepare the site correctly so your slab stays flat and solid for the long haul.

Here is our installation process:

• Site evaluation: We assess the soil conditions, drainage, and slope to determine the best approach.
• Excavation: We dig to the correct depth and remove any organic material or unstable soil.
• Base layer: We add 4 to 6 inches of compacted gravel for drainage and stability.
• Vapor barrier: We lay a plastic vapor barrier to prevent ground moisture from seeping into the slab.
• Reinforcement: We install wire mesh or rebar to strengthen the slab and prevent cracking.
• Concrete pour: We pour concrete at the appropriate thickness (typically 4 to 6 inches for residential use).
• Finishing and curing: We level, smooth, and finish the surface, then protect it while it cures.

Most slab projects take 2 to 3 days from start to finish, depending on the size and site conditions. You can walk on the slab within 24 to 48 hours, but it takes about 7 days to reach full strength for heavy loads.

Choosing the Right Thickness

The thickness of your slab depends on what you plan to put on it. A 4-inch slab works fine for light-duty uses like storage sheds and foot traffic. For garages, workshops, or areas where vehicles will drive or park, we recommend 5 to 6 inches. Heavy equipment or machinery may require an even thicker slab with extra reinforcement.

We will assess your needs and recommend the right thickness and reinforcement for your project. Spending a little extra on the right slab now saves you from costly repairs and replacement later.
