Bonding pea gravel together to form a solid path is one way to make a decorative walkway through a garden or your backyard. Constructing your pea gravel walkway in 24-inch by 24-inch squares allows you to move your walkway in the future and also allows room for expansion due to changes in temperature and climate.
Construct a 24-inch by 24-inch frame by cutting two pieces of 2-by-4 wood into 24-inch lengths, and two pieces into 25 1/2-inch lengths. With each 2-by-4 on its narrower side, place the longer boards vertically to create the sides of the frame. Place the shorter boards horizontally so they make the top and bottom of the frame. Your lumber should resemble a picture frame at this time. Nail the two vertical boards to the top board than then nail the vertical boards to the bottom board using nails and a hammer.
Place the frame onto a piece of plywood, trace the outside of the box with a marker, cut the box you drew onto the plywood out with a saw then nail the box to the bottom of the square frame using nails and a hammer.
Line the inside of the mould with waxed paper. This makes it easier to remove the stone from the mould once it dries.
Mix the pea gravel, concrete and water into the mixing bucket. Use a 2:1 ratio of pea gravel to concrete. Use the specified amount of water on the packaging of the concrete. The amount of water depends on the amount of concrete you mix at one time and the type/brand of concrete you choose to purchase. All brands have different specifications.
Dump the mixture into the mould and level it out with the trowel. Allow the mixture to harden per the specification printed on the concrete packaging.
Place the mould on its side, hold the face of the concrete and tip the mould slightly toward the concrete to remove it from the box. Complete this process for each square you need to complete your path.
