Mortar-setting flagstone

For a permanent and maintenance-free natural stone surface, mortar-setting is the way to go. Highly recommended for primary entries and high-use outdoor entertainment areas and walkways, mortar-set flagstone can be swept, blown or hosed-off without the grit or dirt than is typical of dry-set flagstone. There is little chance of the stones or grout shifting once it is set which makes for a safer, higher utility surface.
