Sand is a crucial material in the installation of pavers. In fact, sand is utilized twice during the installation process. Sand acts as a cushion the pavers and is also utilized for the paver joints to bind the stones together and prevent the growth of weeds.
Step 4 - Pavers and Gravel. After all of the cedar risers are set, pour in pea gravel between each riser on the treads. Fill up the space to just below the top of the planks and level it out. Once the gravel is in place, begin placing the pavers in the tread area. The span should be wide enough to hold pavers of a specific size. For instance, 1x1 foot pavers will fit three side by side in a space 13 inches by 38 inches, that includes some wiggle room. Set the pavers in the gravel until they do not move. You can lightly tap on them with the rubber mallet to set them in further. With the pavers set in the gravel, you now have an attractive walkway up a hillside. Double check your work and make sure the cedar risers are secure in the dirt.
