The answer to how to install a stone walkway is to carefully plan the layout, prepare the ground, and lay the stones in a sturdy, level pattern. Start by marking the desired path of the walkway and excavating the area to a depth of 4-6 inches. Compact the soil and lay a 2-inch layer of gravel or crushed stone as a base. Then, arrange the stones in your desired pattern, making sure they are level and evenly spaced. Use a rubber mallet to gently tap the stones into place, and fill any gaps with sand or small stones. Finally, apply a sealant to protect the walkway from weathering and wear.
Installing a stone walkway requires some physical labor, but it's a project that many homeowners can tackle themselves with the right tools and preparation. However, for larger or more complex walkways, it's often best to consult a professional landscaper who can ensure the job is done correctly and safely.
