If you plan on extending your storage space by installing a shed in your backyard this summer, you are going to want to build a concrete foundation for your shed. This will give your shed a solid foundation and help it be stronger and more durable. Here is what you are going to need to do in order to pour a 8' x 12' concrete foundation for your shed.
#1 Check For Underground Lines
The first thing you need to do before starting this project is make sure that there are not any gas or electrical lines where you want to put your shed. Call up your utility service and have them come out and inspect your property for underground lines before you plan to start your project.
#2 Obtain A Permit
Check with your city code office and see if you need a building permit for your shed. Some cities do not require building permits for small structures, whereas others do. It is best to check before you start construction.
#3 Check The Weather
Ideally, you should pour your concrete when it is warm outside. You don't want to pour concrete when it is freezing outside; the concrete will not set correctly. The best time to pour concrete is when there has not been any rain for a few days and it is warm to hot outside.
#4 Mark The Location
Now you are ready to get down to the real work. Figure out where you want to put your shed and measure out exactly where you want it to go. Spray paint the lines on the ground so that you can clearly see where the pad is to go.
#5 Dig Out The Foundation
The foundation should extend into the ground a couple of inches; this will make the foundation sturdy. The foundation should not be placed directly on top of the ground; the top layer could shift and you want your foundation to be secure. The foundation for the shed only needs to be about five inches thick; the majority of it should be underground, since you only need about an inch to stick out above ground.
You'll want to dig a couple of inches beyond the space you need for your slab so the concrete has some room to settle.
#6 Make A Form
Once you have dug out the area, you need to make a form. You can use 2x6 boards to create a form for the concrete to go into. This will help keep the concrete in place and make the edges of the foundation steady and strong. You'll want to use a level to make sure that the form is flat and even.
#7 Lay Down Gravel
Next, lay down gravel on the bottom of the area where your foundation is going to be. The gravel will help water drain from your slab without eroding the soil underneath it.
#8 Lay Down Steel Bars
Once the gravel is down, you'll want to put reinforced steel bars or rebar across the slab. You'll want to run some about every foot going across, and you'll also want some of the bar to form X with each other.
#9 Wet The Site
Once all that is in place, use a hose to mist the foundation area with a little water. This will help with the cement settle into place.
#10 Mix & Pour The Concrete
The final step you need to do is mix about four bags that contain 80 pounds of concrete according to the directions on the packaging and pour into the frame that you created. As you slowly pour the concrete into place, use either a rake or shovel to smooth it out so that it ends up even.
Allow the concrete to settle for at least a week before you put your shed on it. Click here to learn more about ready mix concrete.Share
