Making a concrete floor for a shed

There are many benefits of having a concrete floor in your shed. Concrete is more durable and easier to clean than other materials.  They don’t chip and can work well in most climates. Making your own concrete floor is not difficult and doing it yourself you can save a lot of money.


  1. Make sure your shed floor is clean and smooth. If you have a dirt floor, spread the dirt evenly with a rake and use a shovel to break up any hard lumps of dirt.
  2. Place wood planks on the bottom of each wall of the barn to make a frame. This will help the concrete be flush. The plates are then removed and are used only as an extra support to help the concrete to maintain its shape as it sits.
  3. Spread a layer about an inch (2.54 cm) thick of crushed rock on the floor and use the shovel to spread it evenly.
  4. Wet crushed stone to make it slightly damp. Be sure not to wet it so much that you get stagnant water. If so, let the water dry before proceeding.
  5. Mix the concrete according to the instructions. Make enough mixture to be able to support a concrete layer about three inches thick. Your package will tell you how much concrete is needed to do this.
  6. Pour the concrete starting from the rear and working forward. Use a concrete spreader to make concrete layer even and level.
  7. Remove the planks once the concrete has set and let dry completely.

Tips & Warnings

  • If you have trouble filling the crushed rock, you can first pour a thin layer of sand underneath.
  • Pour the concrete as soon as possible after mixing it so it does not begin to dry and harden.
