A vertical structure designed and constructed to hold back soil material or to endure lateral pressure of soil is known as retaining wall. The lateral force can be a result of anything starting from earth filling, liquid pressure, sand, and other coarse earthly materials.
The retaining walls in Perth also enhance the beautification of your property by injecting spectacular stonework and hardscaping into the area and by allowing you to convert your landscape in tiers around your central features either by using flowerbeds or by building gardens.
There are different types of retaining wall structures that suffice many goals. In this article, we have discussed the four primary types of them.
Four types of retaining walls and their applications
Gravity retaining wall
The most predominant type of retaining wall is the gravity retaining wall, which uses absolute weight and mass to hold back the lateral earth pressure. This type of wall is massive as it requires substantial gravity load to fight the pressure put by soil.
Since it needs to be heavy and counter-attack the soil pressure, it is generally built of materials such as bricks, concretes, pavers, masonry units, and stone.
3m is the most economical height, that becomes rock solid when there’s at least a small channel dug for the wall to fit into. However, if you want to go with the shorter walls, you won’t need to add any reinforcement.
Piled retaining wall
One of the basic types of wall frequently used where there’s a space crunch is the sheet pile retaining, which is a thin wall of steel, wood, or vinyl, driven directly into the soil. It is not suitable in areas where the soil pressure is too high. And for reinforcement, it is better supported with a vertically corrugated structure.
While installing this wall, make sure that the soil is soft, and for every two-thirds of the sheet above the ground, one-third of it should be driven into the ground.
Anchored retaining wall
This wall is also suitable when there’s a shortage of space and in areas where soils are loose. With different types of “fronts,” it is supported by anchors behind them that are driven into the earth and are joined by cables or strips. Using this method, considerably high retaining walls can be built, and it works wonderfully against overturning and sliding pressure.
Crib retaining wall
This retaining wall is a form of gravity wall. Built by linking individual boxes made from pre-cast concrete or timber. These boxes are further filled with crushed stone or different types of rough granular materials to produce a strenuous structure. Though it’s perfect for supporting planter areas, it can also help structures and slopes.
