This how to is for a retaining wall that is not the most aesthetically pleasing but easy to construct and will hold back a hill up to 6 feet. This will be done by sinking treated beams into the ground and nailing treated lumber to the hill side of these beams.

Difficulty: Moderate
Instructions
  1. Step 1

    First plan your project. You will want to plan the size and height of your wall. This will help in step 2 of determining what you need for the project.

  2. Step 2

    Now that you have your plans you can go and buy your material. The taller the wall the bigger and longer support beams you will want to get and you will have to place them closer together as well. For example if you have a 6 foot wall I recommend 6x8 beams that are 10-12 feet long every 2 feet. You will also need to purchase nails and treated lumber to make the wall.

  3. Step 3

    Prepare your work area.
    -Dig the holes for the support beams
    -Level off the ground where the wall boards will start
    -Dig the hill back a ways so you have room to work.

  4. Step 4

    You will want to put some hard packing gravel in your beam hole and place your beam in the hole and pack it in tight with gravel. Once all your beams are in place (general rule try and have the beams as deep in the ground as they are sticking out) now you can nail on your treated wall boards.

  5. Step 5

    Once you have your walls all built you will want to backfill the area behind the wall. Do this with the dirt you previously removed with one exception place a layer of gravel in between your wall and any dirt to allow for better drainage and longer last wall.

Tips & Warnings
  • You may want to install drain pipes to help direct water away from your wall.
  • These are general guidelines and each wall is different if you are unsure as to what you need or how to design your retaining wall please contact a professional for at least a design.
