One way to build a walkway is to pave a path with stone. Another way to build a walkway is to use wood boards. Many walkways are created using concrete or concrete pavers, while fine gravel is often used as well.
To build a stone walkway, measure the space and use landscapers paint to mark the ground where you want to place the path. Dig a trench at least 6 inches deep, removing all dirt and growth, and level the soil, gravel and sand with a scree or a 2-by-4 board and place landscape fabric over the soil. Add the border of the path using edging and wood stakes to hold the materials firmly to the soil. Add crushed gravel, leaving 2 inches of space, and then add sand to level the gravel before laying the stone. Set each stone into the sand with a rubber mallet, and add sand as needed to keep the walkway from shifting.
To build a wood walkway, place wooden stakes at the terminating points of the path and stretch strings between the stakes to mark the sides of the path. Score the soil under the strings using a shovel, and then remove the strings. Dig 2.5 inches into the soil or sod between the scored lines and cut 4-by-4 posts to fit the measurement. Lay the wood horizontally into the trench, as close together as possible, using a hammer to wedge them as close as possible.
Place landscape fabric between the posts, and then cover the fabric with 2.5 inches of sand. Cut 1.5-by-1.5-inch pressure-treated boards to fit the length of the walkway. Lay the first board and screw two 3-inch screws into the wood on both sides, burying the head of the screw. Repeat until you reach the end of the walkway.
