The versatility of stone makes it all the more useful especially in making your home more enticing and functional. One way to do this is by building a retaining wall made of natural stone.

If you’re thinking of building a flagstone wall according to your style and budget, this article will provide a step-by-step wall construction guide and some tips for a successful home transformation look using flagstones.

7 Easy Steps in Making Your Flagstone Wall

Constructing flagstones usually takes 3-4 days to finish, depending on the complexity of the design that you have chosen. It may require intermediate masonry skills if you decide to get a more complex design.

To help you get started, here are seven easy steps for your next project:

The first step is to locate and identify a specific area in your house where the wall can be built upon. Typically, a flagstone wall is placed in the garden area where landscapes are easy to flatten

Once selected, insert one stick on each end of the area. Remember that the height of the stick must be the same as the height of the wall upon construction.

The design determines the materials you will use, as well as the proper masonry techniques you need to apply. Aside from the overall look, you want to go for, the design should also be practical and cost-efficient flagstone wall.

Shovels will also be useful when you build stacked stones for your garden. A wheelbarrow would do for concrete mixture but this depends on the combination of rocks you decide to use. Rough rocks are relatively harder to bind

You must begin with a strong foundation for it. The recommended depth of the base is 10-12 inches deep which would work best if you aim to construct a 3-4 feet wall.

After digging, make sure that the footings are at the lowest points of the wall so it would not be visible once the stones are stacked. You may place steel bars for curves then add a 2-inch layer of cement on top of it. 

In laying the stones, start with the biggest rocks to the smallest ones. Remember to save a few large rocks for the top layer.

You may vary the shapes of stones you want to place but make sure it still follows the wall’s slope throughout its length. Fill in small spaces and joints as well.

Finish it off with a top rock layer. Aside from its final look of the wall, the top layer is for stability. You may use other materials aside from stones, such as bricks or textured cement. Make sure also to step back and check the stability of each layer.
