STONE WALKWAY

Flagstone is a really popular material that can be used to build spectacular walkways.

The same way we explained on the Flagstone Patio Section, stone contractors have two ways to install this material, both of them have pros and cons, but when done right, the result is a professional looking walk that would improve the look of any house.

I am going to list a few tips and easy steps so you can understand how the installation is usually done (having some basic knowledge is always helpful when dealing with contractors)

Flagstone Walkway on Concrete

These walkways are the most preferred kind. The idea is to install the stone on top of a reinforced concrete base. This procedure ensures that the flagstone will not sink or move with time, leaving you with a walk that will look like new for years.

For this procedure is always recommended to have a concrete base that is at least 4" thick and reinforced with fiberglass or welded wire mesh. This slab should be installed on top of compacted (undisturbed) soil or gravel to add support to the whole structure.

After the concrete is installed, the stone comes next. We recomend that you request the stone contractor to install at least 1" to 1.5" thick flagstone pieces. The thinner the pieces, the more brittle they become with time.

Many contractors might make you think that 2" of concrete or 0.5" thick flagstone would be enough in order to provide you with a cheaper alternative. It is up to you to accept it, but do not expect the stone walkway to last many years if the foundation and material is lacking quality from the beginning.

Flagstone Walkway on Stone Dust and Gravel

Flagstone walkways on stone dust are cheaper and faster to build than the flagstone walkways on concrete. They also have the advantage of being able to be repaired at a much lower cost.

Any damaged or sunk stone could be replaced in just minutes for a new piece, saving you hundred of dollars in the process.

Any good stone contractor should start with a nice 3" to 4" compacted base made out stone dust or CR6 (gravel with stone dust). Depending on the soil conditions.

After having a leveled and compacted base, the flagstone is placed with the correct levels on the ground and the joints are filled with more stone dust. Soil can also be used if you want a more natural look.

Always install thicker flagstone for this application since heavier stones will move less with time.

The downside to this flagstone walkway is that it has more maintenance. Weeds tend to grow in between the stones (even with weed barriers) and some pieces might move or settle with time. Again, both of them are easily repaired if needed.

These are a few pointers for a correct flagstone walkway installation. There are many details and techniques that are not explained here.
