How to Install Flagstone

A well-designed patio is a beautiful home addition with a variety of uses. While creating it is no easy task and it can be costly if professionally installed, it is a worthwhile DIY project with long-term value and enjoyment.

Flagstone is a popular choice for patios because of its flat puzzle-like pieces, but there are other choice stones available. Once you make your selection, devise a plan and get to work!

  1. Design your borders using a garden hose, stakes and twine or spray paint. If you are using our Patioscape coupon, consider a square patio that’s about 15 feet by 15 feet. This is a nice size for tables and chairs.
  2. Dig the area down to a depth of 6 inches. Two inches for gravel base, 2 inches of sand and 2 inches for flagstone and filler. The gravel helps create a stable foundation for the patio. Rent a compactor and use a level tool frequently to insure an even surface. If your patio is directly adjacent to your house, you will want a slight slope away from the house to drain rain away to the garden and not back up to your house.
  3. Arrange flagstone pieces as you would a puzzle, leaving a small gap in between each stone. Tap in each one and use the level along the way to ensure the patio is level or has a slight slope for draining. Arranging the pieces is the most important step in how your patio looks, so take your time.
  4. Fill in gaps between flagstone with more sand, gravel or other filler. Water down the entire path to help settle the sand.
  5. Use the edger of your choice to hold the entire patio in place. For a more polished look, use smaller rocks or crushed granite to fill in between the pavers. If rock is your choice, 1 ½-inch stones are recommended as they are a little larger and less likely to wash away.

Place your new seating on your new patio sit back and ENJOY!
