Flagstone is a natural material that can enhance the beauty of your backyard. The earth tones and organic shapes of flagstone blend with nature rather than compete against it.

If you’re working on your landscaping, use these flagstone patio ideas as inspiration.

What is Flagstone?

Flagstone is a sedimentary rock bound together by minerals. Miners quarry it from an open pit, and a stonemason chisels the rock, giving the stones an organic, unique shape.

Since Flagstones provide a durable and slip-resistant surface, they’re ideal for walkways, patios, pool areas, and driveways.

Flagstones cost about $15 to $20 per square foot, but prices vary by location.

How to DIY a Flagstone Patio

These are the basic steps to flagstone installation using the dry-laid method.

Flagstone Patio Materials You’ll Need:

• Paving stones
• Gravel
• Leveling sand
• Bucket
• Tamper
• Level
• Wheelbarrow

Once you have gathered all of your materials, choose your space and have a design and shape in mind. You can always move the stones around and expand your chosen area.

Flagstone Steps for installation:

• Start by removing grass and other vegetation from the patio area.
• Dig down far enough to accommodate gravel, surfacing sand, and flagstones. This should be between six to eight inches deep.
• Grade the ground so it drains. About 1/8″ of drop per foot of patio will suffice.
• Lay 4″ of gravel base to the ground and pack it with a hand tamper or plate compactor.
• Next, pour leveling sand on top of the gravel and spread to a 1″ thickness. The best material to use is decomposed granite.
• Layout your flagstones using a puzzling method. Use larger stones around the edges as the smaller stones will shift over time. Arrange stones by size and shape into the space, leaving a one to two-inch gap in between the stones.
• Level each stone by moving the stone by hand. You may need to add more leveling sand underneath.
• The final step is to fill the gaps with more decomposed granite leveling sand. You can also soil and plant grass in between pavers.

This dry laying method is cheaper than mortar and grout but will shift over time. If your bed of gravel and sand is compacted right, shifting will be minimal.

Professional Flagstone Patio Installation Costs

A professional installation of flagstone patios costs about $1,500 for a 100-foot surface. You can bring down labor costs by choosing larger stones covering a broader area.

Should You Seal Flagstone?

Although you don’t have to seal your flagstone patio, it will increase the longevity of the stone. An application of sealer hinders weed growth in between joints and prevents mold. It can also prevent stone cracks.

Use a sealer every three to five years, although wear time may vary depending on weather and traffic.
