Backyard Flagstone Patio Installation Guide
There are two methods of installing flagstone on your patios. One is dry construction, and the other one uses mortared flagstone. We’ve put together a detailed installation guide to help you create an outdoor dream space of yours.
For Dry Construction
- First, you must plan everything, including the stone size, thickness, irrigation lines, and proper drainage system. When considering the drainage system, build the surface at an angle of about 1/8″ of drop per foot.
- Once you have planned everything, you need to dig down enough so that the 3-4″ of the packed gravel base, 1′ of leveling material, and pavers can easily be laid. So you need to dig around 6″ down.
- Add a gravel base to keep your patio flat and support the stones. This is the flagstone patio’s foundation.
- On top of the gravel, add 1″ of Decomposed Granite (DG). It can pack down similarly to soil because it contains both larger pieces of sand (1-2 mm in diameter) and fine dust, but it’s still simple to level out, and weeds find it challenging to thrive there.
- Once you have correctly laid a layer of decomposed granite, start laying flagstones. First, begin laying the big flagstones and then smaller ones. The larger stones on the outside and smaller ones towards the center are recommended.
For Mortared Flagstones
- A solid concrete base with a proper slope for drainage is all you need to lay a perfect flagstone patio.
- Start laying each flagstone on the base using a mixture of cement, sand, and water.
- It is recommended to use a color additive to the mortar that settles the base and grout joints between the stones.
- Once properly laid, the flagstones on the base, you should seal them using paver sealant, as it will prevent water and snow from entering the grout joints.
Using flagstones in your patio is a great way to enhance the look, providing a more contemporary yet traditional feel. These stones are versatile, with endless patterns, colors, and textures.
