This may involve leveling the ground, adding a base layer of gravel or sand, and compacting the area to create a stable foundation. Once the ground is prepared, the natural stones can be laid in the desired pattern and secured in place with mortar or sand. Finally, the stones can be sealed to protect them and enhance their durability. It is important to ensure that the installation is done properly to ensure the longevity and stability of the natural stone paving. **
