How to Build a Flagstone Patio
Flagstone patios can be a formal or informal addition to your outdoor living space.
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!
- Design your borders using a garden hose, stakes and twine or spray paint. If you are using our Outdoor Living Rebate, consider a square patio that’s about 15 feet by 15 feet. This is a nice size for tables and chairs.
- 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.
- 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.
- Fill in gaps between flagstone with more sand, gravel or other filler. Water down the entire path to help settle the sand.
- 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!
