Natural Flagstone Patio & Fire Pit

The client requested a flagstone circular patio with a fire pit that would blend with the natural surroundings. We installed irregular blue flagstone slabs over a compacted stone base, using Gator Dust in the joints. The fire pit is surounded with ironstone boulders. The actual fire pit is recessed below the patio and lined with fire brick.

    What is the diameter of the flagstone area?

    Is flagstone slippery when wet? We have a sloped backyard and my husband has achilles issues which makes him unsteady. Would this be ok to use? Or risky to slip on? Thanks.

      I don't think flagstone is particularly slippery, but that depends on some conditions. First, the area should slope a minimum of 3/16" per foot, and a maximum of 1" per foot. 1" is actually a fairly steep slope, and you're more likely to fall simply because of the slope.

      Second, there are different types of flagstone. This project was natural cleft, meaning that it was split along the natural lines in the stone resulting in a somewhat rough surface. You can also purchase "flamed" flagstone; this is cut with a bandsaw, then treated with heat to pop off the cut marks. This is definitely smoother, but still has some texture.

      Third, if the area is subject to a lot of shade, moss can start to grow. This will make any surface slippery, whether it's flagstone, concrete pavers, or even wooden decking.

      Some concrete pavers would have a more textured surface for more traction. You can also use a sealer with grit in it; the grit dissolves into the sealer, and isn't visible when applied. However, it DOES provide great traction! Hope this helps!

      If the flagstone is not sealed it will not be slippery. You should be good to go.

    how do you keep pea gravel from blowing away when you blow off the leaves?

    • Willow Gates Landscaping
      on Apr 21, 2018

      It is tough! You have to control the throttle carefully, but you'll still lose a few. There are also some sealer/binder products that can be applied; this helps bind the stone together and prevent blowing or erosion.

      You don't. I have a flag stone walkway which was filled with small gravel, the gravel is all gone, the flagstones are now elevated about 1-2 inches and some are loose and have broken. The best idea is to lay a thin layer of concrete, 2 inches should be fine if you are not going to drive on it, and then mortar the flag stone in. The other ideal is to just let the grass grow where the cracks are and keep them trimmed back really well.

      You could intentionally plant a grass in between stones to fill the space. Something like this.... but you will have to trim to keep it looking good.

    What do you suggest for small yard with lots of oak roots? Pavers? Flagstone? Are there other applications?

    • Steve Orleski
      on Mar 7, 2019

      You will have to decide where you want your patio and cut the roots with a chain saw or ax. I would then dig down about 1 foot or more around the edge, and lay a concrete border to keep the roots from intruding again. Then you can lay your base and pavers or flag stone. If you are doing flagstone see the answer above about the pea gravel

    Can you give a rough budget estimate for the fire pit patio project (not including walkway)? Thanks

      Hi Mary,

      There's many variables in a project like this, including existing site conditions, slopes, access, etc. Feel free to reach out to us at 717-341-0540 if you'd like more information.

      Thanks, Jeremy

    Looks Great. Nice Work done. I really liked the Use of stone for fire pit. It gives a more attractive look to your surroundings. Flagstone Pathway is also gives brilliant look to your work.
