Concrete Slabs & Flatwork

What We Mean by Flatwork

Flatwork is any horizontal concrete surface that is not a foundation. This includes slabs for sheds, garage floors, equipment pads, basketball courts, and similar projects. Basically, if you need a flat, level concrete surface, that is flatwork. These projects require the same attention to base preparation and finishing as driveways or patios, just adapted to different uses and requirements.

The key to good flatwork is getting the surface perfectly level and properly sloped for drainage where needed. A shed slab needs to be flat so the building sits correctly. A garage floor needs slight slope toward the door so water runs out instead of pooling inside. An equipment pad needs to be strong enough to support the weight without cracking. We match the slab design to your specific use so you get exactly what you need.

Common Slab and Flatwork Projects

We handle all types of concrete flatwork for residential and commercial properties. Here are the most common projects we do:

• Shed slabs: Level bases for storage sheds, workshops, or small outbuildings.
• Garage floors: Durable, smooth surfaces that handle vehicle weight and resist oil stains.
• Equipment pads: Heavy-duty slabs for AC units, generators, pool equipment, or machinery.
• RV or boat pads: Extra-thick slabs designed to support recreational vehicle storage.
• Sports courts: Flat playing surfaces for basketball, pickleball, or other activities.
• Commercial flatwork: Loading areas, storage pads, or work surfaces for businesses.

Each application has specific requirements. A basketball court needs different finish than a storage shed slab. We adjust thickness, reinforcement, and surface finish based on what you are building and how you will use it.

How We Build Slabs That Stay Level

The biggest problem with concrete slabs is settling or cracking due to poor base preparation. We see this all the time with slabs installed by inexperienced contractors. They skip steps to save time, and within a year or two, you have cracks or uneven sections. We do it right from the start.

Every slab starts with thorough site evaluation. We check soil conditions, existing drainage, and what loads the slab needs to support. Then we excavate to proper depth, compact the soil, and add a gravel base. The base gets compacted in layers, not all at once, because that is what creates real stability. We set forms carefully to maintain level and proper slope. The concrete itself gets placed and finished to your needs, whether that is a smooth troweled surface or a textured non-slip finish.

For slabs that will support heavy equipment or vehicles, we use thicker concrete and add steel reinforcement. Control joints get cut at proper intervals to manage cracking. The result is a slab that stays flat and solid for decades. If you are also working on foundation work or need a driveway extension, we can coordinate those projects together.

Determining Slab Thickness and Strength

Not all slabs need the same thickness. A light-duty shed slab might only need 4 inches of concrete, while an RV pad should be 6 inches or more. We calculate the right thickness based on expected loads and use. Soil conditions also matter. Areas with poor soil or high water tables might need additional base depth or reinforcement.

For most residential slabs, we use 3000 PSI concrete as a minimum, though we go higher for heavy-duty applications. We add wire mesh or rebar reinforcement for larger slabs or those supporting significant weight. The goal is to build something that handles your needs without overbuilding and wasting money. During the planning stage, we discuss what you are putting on the slab and how you will use it, then design accordingly.
