Concrete Shed Foundations in Atlanta

A Concrete Shed Foundation That Actually Lasts

Concrete Shed Foundations Built for
Strength, Stability, and Longevity

A shed is only as useful as the foundation it sits on. Without a proper base, wood can rot, floors can warp, and the entire structure can shift over time—especially in Atlanta's wet clay-heavy soil. At Sudlow Concrete, we install concrete shed foundations that give your structure a permanent, level, and moisture-resistant base from day one.

We work with homeowners throughout the Atlanta area on everything from small backyard storage sheds to large workshop and hobby structures. Whether you're purchasing a pre-built shed or building custom, we'll make sure it starts on the right footing.

Concrete Shed Foundation Options

We install two primary foundation types for sheds, and we'll help you choose the right one based on your shed size, site conditions, and how the structure will be used.

Concrete Slab Shed Foundations

A concrete slab foundation is the most popular option for sheds of all sizes. A slab provides a solid, flat floor for your shed that doubles as the foundation—eliminating the need for a wood floor system and keeping moisture, pests, and rot out of the equation.

Ideal for:

  • Storage sheds, garden sheds, and backyard structures
  • Workshop and hobby buildings
  • Pre-fab or kit sheds requiring a permanent base
  • Any structure where a clean, flat floor is desired

Concrete Block Shed Foundations

For smaller sheds or structures where full slab pouring isn't required, a concrete block foundation can provide a stable, level base using stacked CMUs. Block foundations work well for elevated or site-specific installations where full excavation isn't practical.

Ideal for:

  • Smaller storage or utility sheds
  • Sheds on uneven terrain
  • Structures that may need to be relocated
  • Budget-conscious installations

How We Install Concrete Shed Foundations

Every shed foundation we install goes through the same careful process regardless of size.

1. Site Assessment and Layout

We evaluate the site for drainage, slope, and soil stability, then mark and square the layout to match your shed's footprint precisely.

2. Excavation and Base Preparation

We excavate to the appropriate depth and install a compacted gravel base that promotes drainage and prevents future settling.

3. Forming and Reinforcement

Forms are set to match your shed dimensions, and rebar or wire mesh is placed to reinforce the slab for long-term strength.

4. Pour, Level, and Finish

The concrete is poured, leveled, and finished to a smooth surface. We ensure the slab is perfectly flat and square—critical for pre-fab shed assembly.

5. Curing

We allow the slab to cure fully before any construction begins. This is non-negotiable for a foundation that will hold up long-term.

Frequently Asked Questions

Q How thick should a concrete slab be for a shed?

A

A 4-inch slab is standard for most residential sheds. For heavier structures—such as workshops storing vehicles or heavy equipment—a 6-inch slab with additional reinforcement is recommended. We'll advise on the right thickness during your estimate.

Q Do I need a permit for a concrete shed foundation in Atlanta?

A

Permit requirements vary by city and structure size. Many smaller sheds don't require a permit, but larger accessory structures often do. We recommend checking with your local municipality before starting, and we're happy to help you understand what's typically required in your area.

Q Can you pour a slab on a sloped yard?

A

Yes. Grading and site prep are a standard part of our process. We can work with most sloped sites by excavating, grading, and building up the base as needed to create a level pour.


Q How long after the pour can my shed be installed?

A

We recommend waiting at least 7 days before placing a pre-fab shed on the slab, and longer for heavier structures. Concrete reaches full strength at around 28 days. We'll give you a clear timeline based on your project.


Q Is Sudlow Concrete licensed and insured?

A

Yes. Sudlow Concrete is a licensed and insured.

If you’re in the market for driveway paving, look no further—this is the tradesman you want. From start to finish, the experience was exceptional. Communication was prompt and professional, with every call and message returned quickly. The pricing was fair and transparent, and the value far exceeded expectations. What truly sets Sudlow apart is that they stand behind their work. The craftsmanship is excellent, and it’s clear they take pride in delivering results that last. Any questions or follow-ups were handled immediately, with genuine care and accountability. Reliable, responsive, honest, and highly skilled—this is a worthy choice for anyone considering paving services. I would recommend them without hesitation and would absolutely use his services again.

We used Sudlow Concrete to repair and widen the apron of our driveway. The bid was fair and Aaron did not try and oversell us on repairing small cracks throughout our 70 year old driveway. He provided an expert solution to removing unsightly railroad ties and gently sloping the lawn edge to the driveway entrance. The office agreed to our schedule request and the workers arrived on time. The workers worked continuously until the job was completed. The owner called that evening to see if we were satisfied. Wow! Who does that anymore?!! We highly recommend Sudlow concrete.

Sudlow Concrete provided an excellent service and product when installing our new patio. They were easy to work with and followed up our requests immediately. The crew that installed were well organized, came on time and were kind to our landscaping. I would recommend them to any of my neighbors.

We hired Sudlow Concrete to replace our driveway. Bill (Owner) personally came out to review project and followed up with the quote later that day. Reasonably priced compared to other companies. I had to chase after other companies, rescheduling appointments & having to request a written quote - Bill did exactly as he said he would, sadly far too uncommon these days. The office staff promptly & professionally followed up to schedule the project to begin within the week. The crew arrived on time the day the work was to be completed. Our driveway was removed and replaced in approx. 6 hours & the site was clean before they left. A great experience - strongly recommend!

Bill and his team did such an amazing job, and took a lot of care with our project. They were quick, timely, and the process was seamless. Our driveway was in very bad shape—it was old, and we just finished a renovation that busted it up even more. It looks incredible now (not to mention so much safer for our family). Bill was able to widen the driveway by a foot and create a drainage system for us to eliminate erosion. We're thrilled with how it turned out, and he had extremely competitive pricing and a top notch team. Would highly recommend!

Sudlow did a great job repairing a dip in my driveway, and also removing a basketball pole and the concrete underneath. Mr. Sudlow was very professional, extremely nice. The caliber of work was excellent, and the price was right. I highly recommend Sudlow.

Bill called twice to check in! Would use them again! Definitely recommend them!
