About the Thickness of Flagstone

Flagstone pavers are popular in outdoor landscaping because they add a beautiful, natural element to any design. When you design your outdoor space, choose the correct flagstones to get the results you want.

Flagstone Types

Flagstones are usually sold in one of two types: patio or select. Patio flagstones are usually smaller and thicker. They are typically 12 inches long and 2 inches thick. As the name implies, they are used in patios, walkways, and outdoor steps.

Select flagstones are also known as standup flagstones. They are longer, thinner slabs that can be 2 to 3 feet long and about 1 inch thick. These stones can be stacked. They are a good choice for wall caps, countertops, and retaining walls.

It’s best to use thicker flagstones for patios and other surfaces that need to be durable. The thicker the flagstone is, the stronger it is. If you use thinner flagstones, using mortar will make them sturdy enough for almost all uses.

Flagstone Shapes

Flagstones come in two cuts. Cut pavers have clean, straight lines. They come in square or rectangular shapes that create a uniform, elegant look.

Uneven flagstones are loose, round stones that haven’t been cut. You use them to create a rustic or casual look known as “crazy paving.” For both options, you can choose a dry-set or mortar-set installation.

Create Paths and Walkways with Patio Flagstones

Flagstone is an excellent choice for walkways and paths. Installation with mortar will create a more durable surface that can stand up to heavy foot traffic. Flagstones are naturally slip-resistant, which makes them safe for outdoor use and the perfect solution for fountains, pools, and water features.

If you want a decorative pathway in a low-traffic area, set the flagstones without mortar. Add a romantic touch by allowing grass or ground cover plants to grow between the pavers.

Use Select Flagstones for a Retaining Wall

You can use stacked flagstones to build a retaining wall. They’ll work best if you use them for lower walls. You can either stack them dry or use mortar.

Use Thicker Stones in Shaded Areas

Thicker flagstones are more suited to shady environments. These shaded nooks tend to hold dampness that can cause mildew to form on the stones or mortar. To avoid this, use a thicker stone that does a better job of resisting mildew. A mortar setting is a must for your shaded areas.
