Hardscape Materials inventory of flagstone include stones from all over the USA.
Flagstone is a natural stone that is between 1″ and 3″ thick. This type of stone is used for pathways, patios and step stones.

Flagstone is between 1"-3" thick

Flagstone will be stacked on pallets according to their thickness.

One Ton of 1″ flagstone will cover approx 150 square feet
One Ton of 1.5″ flagstone will cover approx 100 square feet
One Ton of 2″ flagstone will cover approx 75 square feet

Palletized flagstone comes in a variety of sizes, thickness and colors. This will help you understand the difference of each type and also aid in the terminology used when ordering.

Patio Stone
This stone will range from the size of your hand up to one half the size of the pallet. Generally with the Patio Stone there will be 4-5 pieces of stone per layer. This is perfect for step stones or a smaller patio. If a pallet has over 5 pieces per layer then it is best to mortar that stone in because smaller pieces will tend to move.

We usually have smaller quantities of patio stone in the self-serve area.

These pallets of stone will have one piece per layer, some times two. Perfect for oversized step stones.  They may be a little hard to wrestle, but once they are in place, they aren’t going anywhere. Stone masons like the larger sizes for patios because they can cover a large area quickly and will have fewer grout joints to deal with. Mixing the slabs with regular patio stone will keep your cost down as the larger pieces cost more.  The porch of our main office at Hardscape Materials is a mix of the Autumn Haze slabs and patio stone.

The slab pallets will usually have one piece per layer.

Small quantities of slabs will be located in the self-serve area.

Stand up or Select Stone
These pallets of flagstone will have even larger pieces than the regular slabs. They don’t hang over the edges of the pallet and load onto the freight truck more efficiently. Most of the flagstone is available as select, slabs, and regular patio flagstone.


The Stand up or Select pallets will have the largest pieces available.

Small quantities of the Stand up or Select will be located in the self-serve area.

If you are laying a mortared patio and you purchase a pallet with large and small pieces, make sure you mix all the sizes together as you go. It’s a natural tendency to grab all the choice pieces because they fit together so easily. You will end up with small and lesser quality pieces to finish with. If you start with the larger pieces and end with the smaller it will be very noticeable. When selecting flagstone, don’t only select for color, but size and quality as well.

Quarried flagstone

Plenty of flagstone choices.

There are basically two ways this stone is produced. Some quarries are lucky enough to have stacked thin layers of stone that are not bonded or are separated by a thin layer of shale, clay or dirt. It’s simply a matter of unearthing this material, and stacking it on a pallet. This stone is referred to as “natural face” flagstone, and has some texture, undulations, and sometimes fossils.
The other method for producing flagstone is to unearth large blocks stone, parting the lamination lines with a sharp chisel and hammer. This is obviously very labor intensive and usually yields larger pieces and a smoother surface.

Harvested_Native2Sometimes stone can be harvested right off the surface. This is usually not a very smooth stone and could almost be classified a simply a thin, smooth fieldstone.

Saw cut
Some flagstones are saw cut into a square, modular pattern. This is accomplished by sawing each piece individually on a guide saw, or is sawn on the floor of the quarry and them popped free and hand split into thinner pieces. Some large limestone quarries saw cut huge blocks of stone into thin slices and sell it as flooring material, that technically is called tile, but big thick pieces are sold as flagstone.

Buying Flagstone by the pound:

  • Weigh vehicle on the scales to get your empty weight. If hauling a trailer, weigh vehicle 1st and trailer 2nd.
  • Head to the self serve area to locate the material you would like to purchase.
  • After loading the pieces you wish to purchase, return to the scales for loaded weight, keeping same number of people in the vehicle as the first weigh in.
  • You will be given a ticket to take to the main office to pay for your stone.


How to:

Wet lay This refers to setting the stones in a bed of mortar and packing the joints with grout. This results in a very smooth surface suitable for walking barefooted and sliding chairs. The general rule of thumb is to make your stone and mortar patio a total of 4″ thick when laid on compacted, consolidated ground. This is adequate for most foot traffic.

Dry lay Without using any mortar, dry lay can sometimes be as simple as plopping down some step stones right onto the dirt. More formal patios can be dry laid but some thought to the base preparation might be necessary. Usually flagstone for a dry laid needs to be thicker to give it more mass and not as prone to tipping when you step right on the comer. Slabs are much better for a dry lay job because of their large size.
