Construct a Concrete Retaining Wall for Landscape

The retaining wall is considered an essential structure for landscape improvement. If you live in a downhill location and the eroded materials are clogging your property, then you have to build a wall for protecting the land. People living at the foot of the hill are in a risky situation because at any time landslides can take place. Retaining wall may provide you with peace of mind because you will be safe from a massive landslide. Today, we will discuss about the construction and maintenance of the concrete retaining wall.

Another problem arises when the house locates at the fault lines of the land. If anybody can’t find out the fault line, he should consult an expert. In this case, soil erosion may not be a major threat, but an earthquake can because a massive earthquake can either lift the land or cause subsidence. Because of all these problems constructing a retaining wall is necessary. Here, we will show our readers a complete guideline to build a retaining structure around their homes.

Things that are needed Concrete Retaining Wall

Building a retaining wall is not so hard. You will only need a few things for construction.

  • Shovel – for excavating the ground
  • Plate compactor or hand tamper – for compacting the soil
  • Stones or gravel – for improving drainage
  • Adhesive material
  • Cement
  • Concrete blocks
  • Level measuring tool (4 feet or 2 feet)

Step-by-step guide for constructing a retaining wall

1. Planning and designing

Many people overlook this step and directly start excavating. But it should not be done because at the beginning, the owner must design the entire project – what should be the height, how much wide he should dig, what kind of wall he should choose, and so on. Preplanning will help him to design the wall and ease the work.

2. Excavation of the ground

Now it is time for excavation. Dig a trench and check the level more often to ensure that the blocks can be set up precisely. This trench will strengthen the wall. After digging it properly, place the gravel and coarse particles in that trench. Try to choose angular stones or gravel because they will interlock better compared to the round ones.

3. Compacting the ground and checking the level

After placing the stones or gravel, compact them by using a plate compactor or hand tamper. Once the compaction is done, check the level with a level measuring tool. Make sure that the entire ground is perfectly leveled because it will help you to construct a solid base. In addition, compact the ground well because it will reduce the porosity and increase the strength.

4. Set up the first layer

Once the compaction is done, you should lay the first layer of the concrete blocks. After placing a few of them, check the level again. If they are leveled, place more. Once the first layer is set up, use the adhesive material and construct the second layer. Make sure that all the layers are leveled. To enhance the drainage, you may use perforated pipes. Once the wall is constructed, use gravel and stones as the backfilling materials instead of native soils.

This is how anybody can construct a concrete block retaining wall for landscape improvement.
