Building a concrete retaining wall is not challenging, especially if you have a basic knowledge about the slope, land topography, and pressure. Here, we will reveal easier steps to build a retaining wall for landscape or home improvement.

Before constructing a retaining wall in the backyard, make sure you check the followings –

  • Slope percentage
  • Soil properties
  • Drainage
  • Climate (precipitation and temperature fluctuations)

Things that are needed to build a concrete retaining wall

  • Tape for measurements
  • Shovel
  • Sledgehammer
  • Hand tamper
  • Construction adhesive
  • 4 feet level
  • Masonry chisel
  • Wall blocks
  • Gravel or coarse sand particles

Steps to Build a Retaining Wall for Home Improvement

1. Excavate the area

Before you start excavation, it is necessary to calculate the area where you want to place the blocks. Use the tape to measure the height and width of the blocks and excavate the land. In addition to this, try to reinforce the wall by extending the base. To do this, you can make wider trenches to place more blocks in there. After making the trench, pour the gravels and stones.

2. Level the earth

Once the gravels and coarse sands are placed in the trench, you need to level the ground by compaction. To do this, the builder can use the hand tamper to compact the soil. The more you can compact, the stronger the base will become. After compacting the soil, check whether the ground has become leveled or not. It can be check by using the sticks and the 4 feet level. Making the ground leveled is necessary to ensure the placement of the blocks is right.

3. Place the blocks

Let us assume that the builder has made the situation ready for you. Now you have compacted soil, now place the blocks carefully. After placing two or three blocks in a row, use the level to check whether they are leveled or not. If yes, then continue your work, and if they are not leveled, manage the height either by adding some stones or removing them from the bottom of the blocks. After placing the blocks use the construction adhesive because the surface of the blocks is not too smooth, and this adhesive will hold the layers firmly. Add a little bit of the adhesive and insert the second layer of the blocks. Check the level once again to determine that the layer is straight and leveled to the ground. Adjust the curves based on your requirements or choices.

4. Backfilling

Once the construction and placing of the blocks are done, it is time for backfilling. Use the coarse sand particles and the gravel materials in this case. Try to use porous materials for backfilling and avoid soils because soils will retain the water and will exert pressure on the wall causing the wall to fail and collapse. Even if you need to use soils, try to mix them with the gravels and insert perforated pipes through the blocks because it will ensure drainage. Since the gravel and sand don’t swell after absorbing water, they are the best choice for backfilling.

These are the four steps to build a retaining wall for home improvement. We hope that a homeowner can easily build a wall for decorating his backyard.
