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.

Sudlow Concrete did a great job in replacing my 40+ year old driveway and poring a sidewalk along the left side of my house. It was easy to request a quote through their website and schedule an estimate. I received my estimate by the end of the day, and it was very competitive with 3 other quotes that I obtained. The work was scheduled within a week and the crew showed up at the time scheduled. A supervisor walked through the plans for the work to be done and gave me his card to contact him if I had any questions or concerns. The crew started work at 7AM and were completed by 1:30PM. I was very impressed with how their entire crew were so organized and coordinated. Everyone knew their job and the proper time to do their part. Demolition, framing, gravel, concrete, were all very efficiently timed. The work site was cleaned after the job, and they also came back and pressure washed the street in front of my house. I have received several complements from my neighbors and have noticed some taking pictures of the Sudlow sign that was left in my yard.

Our experience with Sudlow was spectacular. “Efficient” doesn’t seem a strong enough word! On the day our driveway was to be installed, the crews arrived just before 7am (as promised) and they were done — completely done…I mean, old drive was demo’d and the new drive was poured...
Our experience with Sudlow was spectacular. “Efficient” doesn’t seem a strong enough word! On the day our driveway was to be installed, the crews arrived just before 7am (as promised) and they were done — completely done…I mean, old drive was demo’d and the new drive was poured EXACTLY to our specs — before 1:30pm. And to boot, Mr. Sudlow himself called from his personal cellphone before work started and at the end to offer his assistance (if needed) and check in once work was completed. I thought this kind of customer service was dead! Clearly, it isn’t! AND their office staff is superior! A++ HIGHLY recommend!

For several years, the driveway of our 60-year old house has been cracked and rough. Recently, when we were out of town, our carport cracked and sank about a foot making it difficult, if not impossible, for us to enter the house. I did some research and found Sudlow Concrete who had good reviews. I called and made an appointment with Mr. Sudlow who came out and made measurements and talked about our requirements. He went back and sent me a quote. I accepted the quote and made arrangements to begin work on the following Monday morning. I woke up at 6:45 am that Monday morning and the crew was already beginning to work on breaking up the old concrete on our driveway, carport, turn-around, and front porch using a Bobcat with a jack hammer attachment. Then, they switched to a bucket attachment and scooped up the broken pieces and dumped them into a dumpster to be recycled. After this, they graded the areas needing it, constructed the forms, and started spreading a load of gravel which had been delivered. At this time, the team leader advised us that they were leaving for the day and another load of gravel would be delivered in an hour or so and that they would come back the second day to spread it. On the second day, by the time I woke up at 6:45 am, they had already spread the gravel, laid the rebar and the first concrete truck was already getting in position to deliver the first load of concrete. Once delivered, the team began working the concrete. Over the course of the next hour or so, three more trucks delivered more concrete and all areas were filled in and the workers began smoothing it. By noon, it was all done. They even created a little ramp at the back door in the carport so that we can easily step into the house and even roll a wheelchair into the door, if necessary. We are extremely happy with the work done and compliment Mr Sudlow and the team for their professionalism and courtesy. It was evident they had done quality jobs like this multiple times. Once the job was done, all tools and trash were collected and removed leaving our yard as clean as it was when they arrived the first day. They even placed a barrier so that no one would drive on the driveway until it was dry and cured. We were advised not to walk on the fresh concrete for 24 hours and not to drive on it for 5 days. We can’t wait to try it out. Update: We've walked over the driveway and are impressed by the workmanship and love the new carport, driveway and porch.

On the day of the job, the crew was not just on time for the job, but they arrived early. Again, I was impressed. From removing the old driveway to laying the new concrete, they did a great job. My new driveway is the talk of my neighborhood! A+++
