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.

Concrete-set Installation

Concrete-set installation is the most stable and durable method but is also the most expensive. Flagstones are set directly onto a concrete base, providing a permanent and virtually maintenance-free surface.
