Retaining wall plays an important role for the landscapers. To improve the scenario of the landscape, one can build a retaining wall. At the same time, risky areas like the hilly regions, sloppy land, across the fault line, or at the feet of the hill. People living in these areas realize the importance of these retaining walls because these people face the disaster of soil erosion more often. Here, we will show you a complete guideline about the ways to build a retaining wall. Today, we will discuss about the landscape improvement using the retaining wall.
Build a Retaining Wall for Landscape Improvement
Materials that you will need
- A shovel for digging the land
- A level measuring tools to check the level
- Hand tamper or plate compactor
- Gravel or stones
- Bricks or concrete blocks
A step-by-step guide to building a retaining wall for landscape improvement
1. Preplanning and designing
Before jumping into the field and start excavation, you should start by designing and planning the wall construction. Remember that the base of the wall should be 0.6 times wider than the height of the wall. Make the list and design the activities accordingly because it will easy the entire process
2. Excavating the ground and compacting it
After planning, take the shovel and start digging the ground. Make the trench carefully based on the calculations that you have done before. Excavating the trench is necessary because it will determine the heel or feet of the wall. Once the digging is done, you need to compact it carefully because compacting the soil will increase the strength to resist any kind of shear stresses.
3. Placing the stones and gravel
Once the compaction is done, place the stones and gravel materials on it. Sometimes, placing a geotextile can also be a good idea. Stones and gravel materials will improve the drainage condition and will minimize the pressure approaching beneath the wall. After placing the stones and gravels, carefully compact them. Make sure that you don’t break them during the compacting process. After compaction is done, check the level with the level measuring tool. It is recommended that the ground of the trench should be leveled.
4. Placing the first layout of the bricks or blocks
After leveling the ground, start placing the first layer of the blocks and check the level often. This layer should be leveled because the bottom part will determine the upper section of the wall. A disorganized base will make the appearance less attractive. If you notice that the layer is not leveled, you can eliminate some of the stones beneath the blocks or add some. Use the adhesive material or cement to build the second layer of the wall. Repeat the process slowly.
Many people make mistakes during backfilling by choosing native soils. Remember that the soils have the characteristics to swell after absorbing water, and this phenomenon increases the pressure to the wall. Some walls can’t withstand this pressure and collapse. This is why it is better to choose stones and gravel to fill the backside of the wall.
Lastly, to enhance the drainage condition, the builder may use perforated pipes. By following these steps, anybody can quickly build a retaining wall.
