How to Build A Flagstone Walkway
Building a flagstone walkway is a budget-friendly project that creates a durable, non-slip path that blends seamlessly with grass and landscaping. By incorporating large stepping stones, you can achieve a natural, spacious look while enhancing both functionality and style. Its organic shapes and earthy tones add charm while preventing wear on your lawn, making it a cool addition to any outdoor space.
Materials:
- Flagstone slabs – Sold by weight; the amount needed depends on slab thickness and spacing.
- Sand – The required amount varies based on the number of flagstone pieces. (For reference, a half-yard of sand was enough for the walkway in this tutorial.)
- Shovels – One regular shovel for digging and a hand shovel for finer adjustments.
Note: Wear safety goggles, gloves, and a dust mask when cutting flagstone. Work on a stable surface and take breaks to avoid tool overheating and stone damage.
Step 1: Prepare the Pathway Area
Determine the walkway’s location and width. Mark the path’s outline, ensuring it blends naturally with the landscape. If laying flagstone over dirt or gravel, clear excess material and rake the surface smooth and level.
Step 2: Lay Out and Dig for the Flagstone
First, lay out all your flagstone pieces to ensure a balanced design, considering color, smoothness, and shape. Once satisfied with the layout, dig around each piece using a hand shovel.
Step 3: Prepare the Base and Level the Flagstone
Remove 4”-6” of excess dirt to ensure the flagstone sits flush with the lawn. Pour 2”-4” of sand into the hole, smoothing and leveling it evenly. Place the flagstone back on top, checking for level. Adjust the sand as needed by adding or removing small amounts until the flagstone sits flat and at the desired height.
Step 4: Complete the Flagstone Walkway
Continue the process for each flagstone until all are securely set. For non-grassy areas, remove the top few inches of dirt, spread 2” of sand, and lay the flagstones in your planned arrangement. Clear excess sand from between the stones, then cut and set sod strips for a seamless, natural look.
