Hardscape 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

- Flagstone Walkway on top of 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 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.

Stone Walkway Many contractors might make you think that 1" of concrete or 0.5" thick flagstone would be enough in order to send you a cheaper estimate. It is up to you to accept it, but do not expect the stone walkway to last many years if the material is lacking quality from the beginning.

Irregular Flagstone Walkway

- Flagstone Walkway on Stone Dust or Cr6:

These flagstone walkways are cheaper and faster to build than the ones in 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.

Flagstone Walkway Installation Any good stone contractor should start with a nice 4" compacted base made out stone dust or CR6 (gravel with stone dust).

After having a leveled and compacted base, just place the flagstone on the ground and fill the joints with more stone dust or even dirt if you do not like the bluish color of the dust.

We usually install thicker flagstone pieces for this application since heavier stones will move less with time.
The downside to this flagstone walkway is the weed growth and stone movement. So make sure to install a layer of "weed stopper" or "geotextile" under the base material.

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