how to build a raised concrete patio
  • Hammer
  • Nails
  • Shovel
  • Level
  • Wooden stake
  • Gravel
  • 2x4 wooden boards
  • Wheelbarrow
  • Water
  • Concrete mix (quick-dry is fine)
  • Plastic tarp
  • Pegs and string
  • Vegetable oil
  • Edging tool

    First, figure out the area of the concrete slab. Since one side will be up against your house, you only need to lay out the dimensions for the other three sides. Use pegs and string to mark off the area where you think you want your patio to be located, and then use your level to double-check that everything is correct so far.
  • 2
    Adjust the guide strings slightly so that there is a slope away from the foundation of your home. This slope doesn’t have to be significant, and it should be gentle enough that you don’t really notice it when standing on the patio itself. However, it should be enough of an incline that there won’t be a water runoff problem around the foundation of your house later on down the line.
  • 3
    Lay down your 2x4 boards to outline the perimeter of the patio slab area. You will not need to use boards on the side of the slab where you house is located. Nail the other three sides together so that you have a good frame from which to work when pouring your concrete. Apply vegetable oil to the boards to make them easier to remove later on.
  • 4
    Check to be sure your boards are level before continuing.
  • 5
    Next, determine whether the area where you want your patio to be located is level or not. If it is more or less level, you can skip the digging step and move right on to the gravel step. However, if you find that your yard is fairly uneven, you’re going to need to start digging.
  • 6
    Get your shovel and start digging until the space is level. You may need to dig more on one side than the other, and don’t forget to account for your slight water runoff incline, too.
  • 7
    Once everything is level, tamp the ground down and double-check with your level before you continue.
  • 8
    Spread gravel across the space where your patio will be located. Take time to ensure everything is the same depth—about four inches, give or take a bit. Again, check with your level to make sure you’re keep everything as even as possible.
  • 9
    Mix up the concrete according to the directions on the package. Depending on the type of concrete you chose, you may have different directions than other types, so take the time to read up on this before you go to the trouble to mix it and risk doing so incorrectly.
  • 10
    Spray the ground—gravel and all—with your garden hose.
  • 11
    Pour the concrete into the wooden patio frame and on top of the gravel. Use a spare 2x4 board to spread it evenly. Work quickly during this stage, especially if you purchased quick-dry concrete.
  • 12
    Double-check again with your level before the concrete has time to dry all the way.
  • 13
    ​​​​Let the concrete dry halfway, then use an edging tool to make a slight lip around the outside of the concrete patio slab.
  • 14
    At this stage, use the edging tool or any other similar too to cut a vertical line down the center of the slab of concrete. This will let the concrete expand and contract without cracking and breaking too easily.
  • 15
    Use your tarp to cover the concrete slab and let it dry the rest of the way. Make sure no one steps on it while it’s hardening.
  • 16
    Remove the wooden patio form, which should slide out of place easily if you coated it in vegetable oil first.
  • 17
    Congratulations! You have successfully installed a concrete patio against your house.


Do you feel ready to get out there and get started laying your concrete patio up against your house now? This is a simple and fairly straightforward project that most beginners can accomplish with no trouble. However, if you don’t feel as though you understand all of the steps, it’s a good idea to do some extra research or ask for some clarification from an employee at your local home improvement store. For the most part, this project should be able to be completed without too much time or effort.

While you’re working on putting in your patio, however, you may be concerned about the damage this DIY project could cause to your home. It’s true that there are a few risks, and if you’re worried about your house, you should keep the following tips in mind:

  • Use a tarp or an old sheet to carefully cover the side of the house where you’re going to be working. Cover extra space, too, to ensure you don’t accidentally splatter concrete on the wall.
  • If you do get concrete on the wall, be ready to remove it immediately. This may mean leaving the rest of the project unattended for a few minutes, which could, in turn, be a detriment to your patio laying process. Because of this, it’s always a good idea to have someone else on hand to help deal with any situations that may arise throughout the project so you can focus on getting your concrete spread evenly and quickly.
  • Finally, always be sure to cover any windows around the area where you’ll be working. You never know when something could go awry and lead to a broken window.

If you keep these tips in mind, you’ll be well on your way to a beautiful and high-quality DIY patio laid against the side of your house in no time. Follow our steps and guidelines to ensure you get your patio laid correctly the first time without having to worry about any potential hazards with it later on, too.
