How thick should my concrete slab be?

A shed or patio slab is usually four inches thick. Garage floors, workshops, and pads for heavy equipment run six inches or more with added reinforcement. We size the thickness to the load the slab will carry.

Do I need rebar in my slab?

Most load-bearing slabs benefit from rebar or wire mesh, which holds the concrete together and controls cracking. Light-duty slabs may use fiber-reinforced concrete instead. We recommend the right reinforcement for the job.

Can you pour a slab for a shed or garage kit?

Yes. We pour slabs sized to your building's footprint, level and square, so your shed, garage, or kit sits on a solid, code-ready base.

How long before I can build on the slab?

You can typically start framing after about seven days of curing. For heavy structures, we may recommend waiting longer so the concrete reaches full strength.

Do you travel up to Alpharetta?

Yes. Alpharetta is within our extended service area in north Fulton County, including the Avalon and downtown neighborhoods.

What's Involved in a Slab Project?

A concrete slab is the flat, reinforced foundation under a garage, shed, workshop, carport, or piece of heavy equipment. We excavate to the right depth, lay and compact a gravel base, add a vapor barrier where the slab will be under a roof, and set rebar or wire mesh for strength. Then we pour, level, and finish. Slab thickness depends on what sits on top of it, from four inches for a shed floor to six inches or more for heavy loads.

Signs You Need a New Slab

Here are the common signs it's time to call us about your slab in Alpharetta, GA:

You are building a shed, garage, workshop, or carport
You need a level pad for a hot tub, generator, or AC unit
An old slab has cracked apart or settled below the structure on it
You want a clean, dust-free floor in place of dirt or gravel
You are pouring a base for an outbuilding or storage barn

Why Do Slab Problems Happen?

Slabs crack and settle when the ground under them was not prepared for the load. Skipping compaction, pouring too thin, or leaving out reinforcement all let the slab flex until it cracks. Under a roof, a missing vapor barrier lets ground moisture wick up through the concrete and damage whatever sits on it. Getting the base, thickness, and reinforcement right for the actual load is what keeps a slab flat and solid for the life of the building.

How Much Does Concrete Slab Cost in Alpharetta, GA?

Every job is priced on the details of the site. These are the factors that move the number up or down:

Factor	Why It Matters
Slab size	Square footage drives concrete volume and finishing time.
Thickness	Heavier loads need thicker slabs and more concrete.
Reinforcement	Rebar, wire mesh, and fiber add strength and cost for load-bearing slabs.
Base prep	Soft or uneven ground needs more excavation and compacted gravel.
Vapor barrier	Slabs under a roof get a moisture barrier that outdoor pads may not need.

Repair or Replace: How to Decide

A slab with minor surface cracks that is still level can often be repaired or resurfaced. But if the slab has settled, cracked through, or is no longer strong enough for what you are putting on it, replacement is the right call. Pouring a new slab to the correct thickness and reinforcement for your actual load is cheaper than dealing with a failed floor under a finished structure.
