A retaining wall is an essential structure for land conservation or for enhancing the beauty of the backyard. Many homeowners build this wall in their backyard for beautifying the gardens and for planting more flowers. Natural stone retaining wall holds the soils in their own place and prevent landslides in a sloppy area.
When it is about the construction of these structures, many people do a lot of mistakes. As a result, these structures can’t stand for a longer period. Here, we will reveal some of the common mistakes that the owners should never make during the construction of the natural stone retaining wall.
Natural stone retaining wall and things to know:
1. Avoiding soil compaction
Many homeowners don’t realize the benefits of soil compaction during constructing the retaining structures. Soil compaction increases the shear strength of the soil, which in turn, increases the ability to withstand greater stresses. If the ground is not compacted, several problems may arise, including water pressure, less shear resistance, landslides, collapse, and so on. After compaction, the soil doesn’t let the water pass, which prevents the stresses. This is why you should compact the ground during the construction of these structures.
2. Not focusing on the drainage
Improved drainage condition facilitates the infiltration rate. People often overlook this, which ultimately collapses the wall. To improve the drainage condition, you may have to spend a few more hours. Before placing the first layer of the blocks, place the gravels and stones because these will improve the drainage. Remember that native soil has the properties of swelling and shrinking. Therefore, if these soils remain right under the structure, the swelling and shrinking properties may cause cracks. Due to all these reasons, the owners should focus on the drainage, and at the same time, he should not place the native soil immediately to the wall.
3. Choosing wrong materials for construction
During construction, people often choose the wrong materials like wood or bricks. Remember that wood can increase the beauty of the entire appearance, but the problem arises when precipitation is too high. When timber absorbs water, it gets decomposed faster. In addition, because of the invasion of termites, the structure may collapse very soon. On the other hand, bricks can also be a problem in the coastal areas because of salinity. The saline water slowly weakens the bricks and causes massive destruction. Though timber is easily accessible, it is better not to use them if you live in a tropical region. We encourage the homeowners to use the concrete blocks or stones for constructing the retaining wall for home improvement.
4. Unconscious about backfilling materials
This is the last step, and many people, unfortunately, make mistakes during the backfilling. While doing it, they use native soils behind the wall, and some people also use organic soils. None of these should be used because soils can retain water for a longer time, and when it absorbs water, it starts swelling. As a result, the pressure on the retaining wall increases significantly. It is better to utilize the coarse sand or stones for backfilling purposes.
These are the common mistakes most people generally do.
