Dry-laid installation involves laying flagstones on a layer of sand or gravel. This method is less labor-intensive, therefore generally less expensive. It also offers excellent drainage but may require more maintenance to keep the stones level.
Mortar-set Installation
Mortar-set installation involves setting the flagstones in a bed of mortar. This method offers more stability but can be more costly and time-consuming to install.
