How to Make an Outdoor Basketball Court Floor

Updated February 22, 2017

Constructing your own outdoor basketball court requires quite a bit of time, effort and energy, but it is possible without a lot of previous experience. The ability to play basketball at any time creates the opportunity for hours of exercise and family fun. The most common material for making an outdoor playing surface is concrete, so laying a basketball court is technically the same as pouring a concrete slab.

  1. Measure and mark off a 30-foot by 30-foot area using a measuring tape after determining where you want to place your court. Place boundary stakes on each corner in order to easily remain within the boundaries.

  2. Dig out the entire section to a depth of 8 inches, removing any large pieces of debris or rock that may be in the area to ensure that your playing surface will be even.

  3. Spread 5 inches of gravel throughout the surface area. Use a rolling device to compact the gravel to make sure it remains flat prior to pouring your concrete.

  4. Mix the concrete in a wheelbarrow using the easy-to-use instructions on the back of the bag. Let the concrete cure for 12 to 24 hours prior to spreading it on top of the gravel.

  5. Pour the concrete 3 inches deep along the entire playing surface. Use a trowel to smooth out the concrete and to spread it evenly along the entire playing surface.

  6. Allow 24 to 48 hours for the concrete to dry before applying the stencils or tape marking the playing lines on your court.

  7. Measure the appropriate court dimensions using a measuring tape. Remember that the foul line is 15 feet from the backboard and the three point line is 19 feet, 9 nine inches from the front of the rim. The lane area is 19 feet long extending from the baseline to the free throw line by 6 feet wide.

  8. Apply the stencilling kit or basketball line tape to the court.

  9. Tip

    Although simple shovels will work, many equipment rental businesses offer digging tools that will make the job much simpler.


    Not allowing the concrete to cure and dry once it is on the playing surface will cause it to be uneven which could result in injury during game play.
