Gravel walkways are best suited to low-traffic areas and flat ground, where the gravel won’t migrate downhill. This DIY paver walkway provides a clean and attractive route through the yard. Concrete pavers offer a wide range of colors and patterns, are easy to install, and are relatively inexpensive. Interlocking paver blocks are also available, making the process of laying paver patios and paths even easier. Expert Advice: To calculate the amount of sand (or gravel) you’ll need for a paver stone walkway, multiply the path length (in feet) by width (in feet) and then multiply by the desired depth of sand (in feet) to determine cubic feet. Divide by 27 to determine cubic yards. If desired, install the weed barrier. Make a screed from a 2x6, notching it equal to the thickness of the pavers. Add enough sand to form a 2-inch layer. Screed the sand to form a level bed. Moisten and tamp the sand until it is well packed and smooth.
