Instructions:
1. Select the Patio Space
Choose a location that is level and free of vegetation. Avoid steep slopes, as pea gravel can shift. Ensure that the area is not in a high-traffic zone to prevent the gravel from scattering.
2. Order the Gravel
For a 16-foot by 16-foot patio, 3 inches deep, you will need approximately 1.58 cubic yards of pea gravel. Order a full 2 yards to ensure you have enough to replenish lost gravel over time.
3. Square the Perimeter
Mark off the perimeter of the patio using twine. Measure the diagonals to ensure the frame is square.
4. Excavate the Area
Remove all vegetation, rocks, and debris from the patio area. Use a shovel or mattock to cut away any roots.
5. Rake and Tamp
Level the soil with a rake and compact it thoroughly by walking over it or using a hand tamp.
6. Lay Out the Frame Timbers
Arrange the landscape timbers to form a square. Overlap the timbers at the corners to create a secure frame.
7. Secure the Timbers
Drill three 1/2-inch holes through each timber and drive a 12-inch length of #4 rebar into each hole. Drive the rebar flush with or slightly below the surface of the wood.
8. Install Landscape Fabric
Roll out the landscape fabric over the entire patio area, overlapping the strips by 4 inches. Secure the fabric with landscape fabric pins.
9. Add the Gravel
Toss shovelfuls of gravel over the landscape fabric to secure it. Fill in the bare spots and spread the gravel evenly with a rake. Smooth the surface with the rake and spray it with water to clean it.
