Question: How To Install A Flagstone Patio

What do you put under a flagstone patio?

For a lasting installation, a dry-set stone patio does need a foundation, though. It’s best to start with several inches of compacted gravel, followed by a layer of stone dust, also called decomposed granite, or DG. The DG is pulverized stone and contains small pieces along with gravel-size and sand-size particles.

Can you lay flagstone directly on dirt?

Consider using flagstones that are at least 1-1/2 inches thick as stepping stones or patio flooring. With the latter, flagstones can be laid directly in soil or a bed of sand. Thinner slabs should be laid in wet mortar or concrete to prevent cracking when stepped on.

How do you install flagstone pavers on dirt?

Because flagstone is relatively heavy and since it’s acid resistant, it can be laid directly on dirt surfaces. This is accomplished by simply smoothing out the soil, placing the stones, leveling them out, filling in the gaps, and piecing them all together.

What is the best material to put between flagstone?

Sand: Sand is the most common joint filler, but it is challenging to keep in place and needs to be refilled. Rocks: You can use small rocks to fill large gaps, and gravel or crushed rock can be used to fill smaller gaps. Mulch: Bark and lightweight chunks of mulch are a great option for in-between flagstone.

How much does a pallet of flagstone cost?

Flagstone pallet prices range from $600 to $2,200, or $0.20 to $0.55 per pound. Pallets weigh around three to four tons. One covers 210 to 560 square feet, depending on the dimensions of the stone.

Do you need sand under flagstone?

Polymeric sand can be great and can prevent weeds and grass from planting between stones, but be sure the spaces you’re filling between your stones are no wider than 1-1/2” and ideally as deep as the height of the stone to be sure the sand sets. Wide and shallow spacing can cause sand to crack and loosen.

How do you lay flagstone on uneven ground?

Lay flagstones on individual beds in uneven ground by placing the stone and tracing its outline in the ground with a trowel or shovel. Dig out that area to twice the depth of the stone, fill it with sand, compact the sand with a tamper and set the stone in place.
