1. Site Preparation & Excavation
Stake out the area where the wall will be installed. Attach a string line to the stakes at the estimated height of your finished wall using a string to make sure that it is level. Trench width should be twice the depth (front to back) of the block. Trench should be deep enough to bury half of the block of the first course plus 4″ compacted base material. Measure down from the finished height in 4″ increments to determine placement of the first course.
2. Base Preparation
Tamp the soil in the trench with a hand tamp to create a rigid surface. Add 2- to 3-inch of base material to the bottom of the trench for the placement of the first course of wall block. Make sure it is a uniform, level surface.
3. Leveling and Laying Block
Use a hammer and chisel to remove rear lips from all blocks for first course. Lay the first course of wall block starting at the lowest point on the project. Lay wall blocks side by side, level block in both directions. Stack additional courses with the bond staggered on the course below with rear lip facing down. Adjust with rubber mallet to level if needed.
4. Filter Fabric
Place filter fabric behind wall extending from bottom of base course to middle of top course. As you build each course, fill behind block with drainage aggregate that extends 6″ behind wall. Compact with tamper.
5. Cutting Block
Mark wall block where a cut is needed. Use a hammer and chisel to score the block on all sides except the face. Pound the chisel on the score line until it breaks.
6. Capping Wall
To cap wall, slide cap forward so the cap over hangs by 1 inch. Glue cap to secure.
Now that you have the installation guidelines here are some design ideas.
Have fun designing your own unique wall creations!
