Cement blocks are comparatively less expensive than other blocks, and they are great for regions with heavy rainfall as they can be reinforced with rebar. Landscaping blocks are elementary to install, and they are great for smaller yards while they are on the expensive side when compared with other blocks.

2. Plan the Process

Examine the area where you wish to build the retaining wall and determine the height of the retaining wall you wish to see in your yard. It is essential to plan the process of building the retaining wall.

To mark a straight wall, try to mark the entire bed using a marking point or a string. In the case of a curve wall, use a rope to mark the outline of the wall. Examine the area and determine the type of soil and not for any drainage patterns. If the slope surface of your yard is advanced, you may require hiring a professional to build the wall.

3. Calculate Your Material

The next step is to calculate the materials you would need to build the wall and remember to add extra 10% material to cover extra blocks. To calculate, determine the number of blocks you would require and divide the total length of the retaining wall by the length of the block.

Example- If the wall if 10 feet in height and 6 inches wide, a block is 6 inches long and wide, you will need 20 blocks for one course.

4. Start the Process of Digging

Now that you have planned and determined the area where you will be building the wall, it is the time when you start digging the trench to build the foundation. Dig the trench to twice the width of the thickness of the wall. For a 2 feet long trench, you would need to dig about 6 inches deep.

5. Tamp Down the Dirt

To form the foundation of your retaining wall, the next step is to tamp down the dirt. Clay soil will require more retention than sandy soil, so the clap soil should be well-compacted.

Now tamp the dirt down until the soil is completely compacted with the use of a hand tamper or a vibrating compacter. Then lay the gravel or crushed stones in the trench and tamp everything down.

6. Start Placing the First Layer

Now, place the first layer of stones on the trench that you created, be assured that your first layer is placed properly, so take your time to place the first layer. Make sure every block fits together and is strong enough to hold the wall.

7. Complete the Next Layers

Now that you have placed the first layer of the block, place the next set of blocks too. Remember to sweep off the excess dirt to ensure that the surface is clean to place other blocks. You can also add cement mix to place other block layers to make it stable and sturdy that lasts longer.
