Pros of Split Face/Mosaic
Cons of Split Face/Mosaic
The first step will be to make the area where you want your wall. Use a shovel to mark the ground, and at the ends of the wall drive wooden stakes into the ground. Tie a string to each stake at the height you’d like your wall. If you are building a long wall, make sure to add additional stakes, as each stake should only be 8 feet apart. Lastly, use a line level to ensure the string is level.
The next step is to dig a trench about 8 inches deep. When doing this make sure your shovel is straight down, so you are not disturbing the surrounding soil. Once your trench is dug you need to tamp down any remaining soil. Once you have done this, and about 4 inches of gravel and rake it smooth. The use your level to make sure the gravel is level.
Now that the first course is down, it’s time to install the drainage pipe. Make sure your pipe is covered with a sleeve to prevent any clogging. Always make sure to place the end/exit of the pipe where you want the water to drain.
Now it’s time to start adding additional layers to your wall. First make sure you sweep away any debris on top of the first course. Now you can start laying down more blocks, of course checking each one to ensure it is level, and using different color blocks if building a mosaic wall. When adding layers make sure you are also adding some gravel as backfill, so that you are covering the drainage pipe.
Once you have finished adding all of your additional layers, it’s time to lay down the topper blocks. Make sure to sweep any debris off of the last course before laying down topper blocks. Use your caulking gun to lay down some a bead of concrete on the top layer to keep the topper blocks in place. Press down on the block firmly once you have added the adhesive.
Once your adhesive has dried you need to add gravel to finish off the backfill and make sure to add some topsoil when you reach the desired level.
