Foundations for Backyard Metal Sheds in Gainesville

A poured concrete pad is the best base you can put under a metal shed here in Gainesville. It keeps the floor level, holds the anchors tight, and gets the metal up off wet ground so the bottom panels don't rust out. If you're deciding how to set your shed, pour a slab and do it once.

I'm Steve Sommers. I run A2Z Concrete with my two sons, and we pour shed pads all over Alachua County. Here's what goes into doing one right.

Why pour concrete instead of gravel or pavers?

Gravel shifts. Pavers settle unevenly. Both let moisture wick up into a metal shed, and around here that's the fast track to rusted-out bottom panels and a door that won't close square.

A concrete slab gives you one flat, solid surface the whole shed sits on. The anchor points for a metal building want something they can really bite into, and concrete holds those anchors far better than loose stone.

It also keeps critters from tunneling up underneath, which matters more than people think once the sod goes down around it.

What does our Gainesville soil and weather do to a shed pad?

A lot of our ground in and around Gainesville is sandy, and sandy soil drains fast but doesn't always sit still. Add our summer rain and the way the water table can come up, and a pad that wasn't prepped right will tilt or crack at the edges over time.

That's why the prep underneath the slab matters as much as the concrete on top. I compact the base so it's not going to settle, and I set the pad so water sheds off it instead of pooling against the metal.

Our afternoon storms dump a lot of water in a short window. If the pad sits in a low spot in your yard, I'll talk to you about grading or a slight slope so you're not parking your shed in a puddle every July.

How do I build a shed pad that lasts?

Every job's a little different, but the sequence is pretty consistent. Here's roughly how a shed slab goes when I pour one:

• I walk the spot with you, check how level it is now, and look at where water runs during a hard rain.
• I strip the sod and organic material off, because you never want to pour over soft dirt or roots.
• I build the base, compact it, and set my forms to the size and square your shed needs.
• I lay reinforcement in the slab to help hold it together.
• I pour, screed it flat, and finish the surface so it's smooth and the shed sits true.
• I set it to shed water, and I give it time to cure before anything heavy goes on it.

The thickness and the edge detail depend on what you're putting on top. A light metal garden shed is one thing. A bigger building where you'll park a mower and shelving is another, and I'll size the pad for the load you actually plan to put on it.

Should the pad match my shed, or be a little bigger?

I usually like the slab to extend a bit past the shed footprint so you've got a clean edge to walk on and water drips off the roof onto concrete, not onto the dirt right against the wall.

Bring me your shed's exact dimensions, or the kit box if you've already bought it. The anchor pattern and door placement matter, and I'd rather form the pad to fit your specific building than guess and have you fighting it on assembly day.

If you're not sure what size shed you're getting yet, that's fine. I can walk the yard and we can rough out where it should go and how you want to use the space.

Do I need a permit for a shed pad in Gainesville?

That depends on the size of the structure and where you are, and the rules differ between the city of Gainesville and the unincorporated parts of Alachua County. I'd treat it as a real question rather than an afterthought.

Your local building or permitting office can tell you exactly what applies to your address and your shed size before you commit to anything. They deal with this every day and they'll give you the straight answer for your lot.

What will it cost to pour my shed pad?

Honest answer: I can't put a number on it until I see it. The price comes down to the pad size, how level your yard is now, how much prep the base needs, and whether I have good access to get a truck or wheelbarrows to the spot.

A flat, open backyard off a quiet street in northwest Gainesville is a very different job than a tight side yard behind a fence with a slope to it. Those things swing the number enough that quoting you sight unseen would just be a guess, and I don't do that.

The estimate visit is free and takes about fifteen minutes. I'll look at the spot, talk through your shed, and give you a real number for your job.
