What Is Flagstone?

Flagstone is a sedimentary rock which is usually made up of feldspar and quartz. Flagstone is perfect for paving walkways, steps, and patios because it splits well along the plane, is highly durable, and is beautiful to look at.

How Much Does Flagstone Cost?

The price of flagstone will vary depending on a number of factors, including:

  • Availability
  • Transportation costs
  • Variability of the stone
  • Whether it is cut or uncut

Generally, the price of flagstone will range anywhere from $3.90 to $11.00 per square foot, according to Blackwell Masonry. If you add in the cost of installation, then the price will probably be around $15 to $30 per square foot.

Tips on Purchasing Flagstone

1. Inspect the pallets before you purchase them: Look for the most consistency in the pieces. You want stones with 2 relatively flat surfaces and clean edges. If you are making a patio, it's best to have stones of the same thickness; if you are constructing a wall a variety of thicknesses is better.

2. Ask about the return policy: A good supplier will take back the unbroken stones that you haven't used.

3. Wastage of 5% to 10% is normal: According to Dream Yard.com, when you are dealing with natural stone, you will have pieces that are unusable. Try to find creative ways to in incorporate these in other locations in your garden.

How Much Do I Need to Build a Wall?

On average, 1 ton of stone will give you approximately 30 to 35 square ft. of wall facing, according to Dream-yard.com. If you are building a wall, you can use this formula to determine the size of your wall:

(wall length X wall height)  +  (wall length X wall width)  = wall cubic feet

Next, divide your cubic feet by 35 to determine how many tons of stone you will need.

For example, if you wall is 20 ft. long, 3 ft. high, and 1 ft. wide your calculation would be this:

(20 ft. X 3 ft.) + (20 ft. X 1 ft.) = 60 + 20 = 80 cubic ft.
80 cubic ft. divided by 35 = 2.3 tons

Therefore, you would need 2.3 tons of flagstone for a wall of the above proportions.

How Much Do I Need for a Patio?

Two inch flagstones are most widely used to construct patios and walkways. If you have a lot of stones that are only 1 3/4 " or are 2 1/4", the difference in thickness can really throw off your estimates. Generally, when a quarry puts a pallet together for patios, they try to have no more than 1/4" difference in the thicknesses. Usually, one ton of 2" thick flagstones should cover about 70 to 80 square feet of patio, according to Dream-Yard.com.
