  1. At first, prepare the footing. Lay out that wall and carefully excavate the slope because the right calculation and measurement will make the installation easier for you. Build the footing and add the rebar into the moist/wet concrete at a specific interval based on the core size of the blocks.
  2. To lay another course of those concrete blocks, enter the weep holes into the mortar after placing the third block, and the diameter of the pipe should be approximately 3 or 4 inches. These pipes will drain the water.
  3. After placing the pipe, don’t seal it with the cement. While using the cement, stop occasionally and check it. Don’t use excess mortar in this step.
  4. After setting a minimum of two courses in the trench, spread the landscape fabric material on the land. Place the gravels and rocks to retain the position of the fabric during working. Between the slope and the wall, slowly backfill your retaining wall with the gravels and keep laying the perforated pipe on the bed.
  5. Now, dig more stones and gravels on the top and backfill with more stones. Now fold that landscape fabric material above the gravels and backfill by using soil this time.
  6. At this step, the builder needs to fill the holes of those blocks with cement. Before filling this, make sure that you have reached the desired height of the wall. Now fill the cores with the mortar. Use a trowel to smoothen the top of the blocks and spread if there is any additional cement.

Following this instruction can help a builder to build a simple concrete retaining wall to conserve his landscape. It will increase the beauty of the land and landscape design.
