Metal retaining wall can be a fascinating addition for the home yard if it is sloppy or leveled. It can increase the beauty of the yard, and at the same time, it can protect the soils from being eroded. If a homeowner faces problems because of having a slope gradient in his land or has possible risks, he should construct a retaining wall to protect the land.
The scientific mechanism behind a landslide is crucial to realize. The splashing effects of the raindrops can disrupt the soil particles and may cause sedimentation. Knowledge of soil’s shear strength, shear stress, shear resistance is very important to realize this. Water decreases the shear resistance of soils. As a result, the soil can’t withstand the stress and get collapses. Building a retaining wall can be a good idea to increase the slope stability, and many people are now trying to build one for conserving their lands.
How to Build a Simple Metal Retaining Wall for Home Yard
Materials that are needed
- Stakes, trenching spade, twine, round-point, and long-handle shovel
- Wooden dowels
- 8 feet lumber
- 4 feet long level
- Metal, base materials, crushed gravels, sand
- Construction adhesive, perforated pipes for draining, torpedo level
- Hand tamper
The procedure for constructing a wall
Step – 1
In this step, you have to excavate the soil, but before doing that, it is required to design the wall whether it should be a straight one or curved. The design will help the builder to place the stakes and twine, which will accelerate the excavating process. If the height of the wall is 3 feet tall, the width of the base should be 0.6 times wider than the height.
Step – 2
After the excavation is done, it is time to ensure that the base is completely leveled. To create a structurally strong wall, you should focus on the base materials and leveling the ground. It is important to place the first layer of the concrete or blocks to place in a uniform and leveled format. To make sure that the ground is completely leveled, the builder can push two stakes into the soil and can check the level with a wooden dowel.
Step – 3
After ensuring that the ground is leveled, the builder needs to compact the base using a hand tamper. For larger projects, it is recommended to use gas-powered tampers. Compact the initial few inches of the soil, and after that, compact a bit more. A mix of gravel or sand materials can be used as the base materials, and one can get it from any home improvement store. Avoid using soil in this step because the soil will slowly settle down.
Step – 4
Level the base once again and check it with the wooden bowel. Remember that the base of the retaining wall must be stronger to withstand the pressure. After ensuring that the ground is leveled and flat, place the base blocks. Make sure that these base blocks are also leveled. Remove or add sands or gravels to adjust the height. Once they are flat and leveled, it is time to use native soils at the front side to ensure that those blocks are fit.
Once building the base of the wall, add another layer of the blocks over the first one, and repeat the process. Don’t forget to backfill the place with the gravels and small stones. In this way, you can easily build a simple retaining wall for your home.
