Cement Flooring

[ARCHER]

Hello, new to forum. Gonna build a small 16x24x8 1 car garage for primarily storage, maybe a small boat/trailer, maybe a small car or 1500 Dodge truck. My question after reading on this forum for thickness of floor is lots of people say 6 inches, but also a lot say 4 inches. If I were doing this myself and based on what I've stated, my guess is 4/5 inches with wire or rebar should be fine for what I need. Since we are only talking about 384 square feet floor am I right for 4 inch thickness? How deep should the perimeter footers be? BTW, I am in Central Indiana so gets cold in winter. I already have a gravel base of about 3 inches.....do I need more? tks in advance for any guidance.

your city/ town will have specs on what they require/
I'm in the process of planning roughly same size garage. I need to do a 18" thick overall perimeter with 8" wide base , angled 45 degrees up from the base to the inside. floor , everyone recommends 6" for floor
a few hundred $$$ in savings of concrete will go unnoticed after the fact, scrimp on it and have cracks/heaves later & you'll be pissed

Definitely check with your area's code requirements, especially if they are strict. I Would hate to do a project & have to redo it because they are demanding. A neighbor of mine told me California was like that when he lived there.

As for thickness, I agree with going thicker. Just use an adequate base & make sure it packed down well. Definitely rebar. Good luck!

This all depends on how far apart your saw cut joints are going to be on the floor. If you space them close together (10 feet) or don't care about small shrinkage cracks, wire could be fine. If you need to space them out further and want insurance against cracking, you'll want more reinforcement.

For your describe use, 4 inchs is good.
