One of the best areas of any home is the garage. It works best to protect your cars, store goods, or create a home gym. It’s easily the most versatile room in the house and one that you shouldn’t take for granted.

But what if you don’t have a garage? How do you build a garage?

It all starts with building a garage foundation.

This quick guide will show you how to build a garage foundation for your home.

Digging and Filling

Dig the space where you want to build your garage. The foundation should be 1 foot wide by 18 inches deep. You should also dig out 2 inches of slab area. This is where you will later add sand and a vapor barrier.

Then, you want to have to take form boards and put them in place. These should be 2 by 10 and are for pouring concrete in. You also want outside form boards to be 6 inches higher than the height of the slab.

Putting It Together

Next, you are going to lay the foundation down to keep it in place. 

You have to take a 2 by 6 form board. This form board should be placed 6 inches from the inside of the outer form board. These forms should be placed all over the garage foundation.

Next, you have to take two rebars (#4 or 1/2 inch) and run them horizontally at the bottom of all footings. When placing these rebars, keep them 3 inches away from the earth at the bottom and sides of the foundation.

Take this rebar and place it on the top of the footing as well. Once again, it should be kept 3 inches away from the air.

Next, you want to hammer down the foundation bolts. Later, when you’ll have to build your garage you’ll need sill plates. These sill plates will get held down by these bolts. You should spray the inside of the form boards using diesel fuel.

Final Touches

Next, pour 2 inches of sand in your slab area. In the middle of your sand, you should place a 5-mil vapor barrier. Once you’ve done this, rake the sand until the surface is smooth. Gingerly pour water over the sand. Then, layout your rebar grid 16 inches on center.

Then you have to pour concrete into the footings. Once poured, wait a few hours and then remove the inside form board. Afterward, you can pour the garage slab.

Once this is done, you have your garage foundation. You can consult with construction experts on how to then build your garage. Make sure to ask about the right materials, such as pole barns when shopping for material.
