How to Install a Keystone Retaining Wall

Keystone retaining walls are a popular and versatile way to add structure and style to your outdoor space. They are relatively easy to install and can be customized to fit any size or shape. In this guide, we will walk you through the essential steps of how to install a keystone retaining wall.

Materials You'll Need:

* Keystone blocks * Edging (optional) * Gravel or crushed stone * Landscape fabric * Level * Tamp * Measuring tape * Shovel * Plate compactor (optional)

Steps:

1. Plan and Mark the Area: Start by outlining the area where you want to build your retaining wall. Use stakes and string to mark the perimeter and determine the height and length of the wall. 2. Excavate and Prepare the Base: Dig a trench along the marked area, approximately 12 inches wide and 6 inches deep. Line the bottom of the trench with landscape fabric to prevent weeds from growing through. Fill the trench with gravel or crushed stone and compact it using a tamp or plate compactor. 3. Lay the Base Course: Place the first row of keystone blocks along the edge of the excavated trench. Use a level to ensure the blocks are level and aligned properly. Backfill the space behind the blocks with gravel or crushed stone and compact it. 4. Build the Wall: Continue stacking the keystone blocks on top of each other, alternating the direction of each layer to create a staggered pattern. As you build, ensure each block is level and tightly fitted against the previous one. 5. Edging (Optional): If desired, you can install edging around the top of the wall to provide a finished look. Use stakes to secure the edging in place. 6. Backfill and Compact: Fill the space behind the wall with gravel or crushed stone, compacting each layer as you go. This will provide support and prevent the wall from shifting or settling. 7. Finishing Touches: Once the wall is complete, you can add soil and plants around the base to enhance its appearance and provide additional support. Water the plants regularly to encourage growth and help stabilize the soil.

Tips:

* Use a variety of keystone block sizes and colors to create a more visually appealing wall. * Angle the wall slightly towards the back to improve stability and drainage. * Rent a plate compactor for a more professional and durable finish. * Allow the wall to settle for a few weeks before adding heavy loads or plants on top of it. * Regularly inspect and maintain the wall, repairing any loose blocks or erosion as needed.
