If you have received an advice to build a retaining wall in your garden and are wondering what it is, understand that a retaining wall is especially useful if your land is sloping or uneven, because it acts as a barrier to hold back or stabilise soil which would otherwise fall down because of the sheerness of the slope.

Though they are useful, retaining walls are also a great gardening feature and also can help you make the best use of sloped land.
Depending upon the application, you can have different types of retaining walls Eastern Suburbs from Amico for examplecan construct for you.
Here are prominent types of retaining walls.
1. Gravity Retaining Wall
A gravity retaining wall is the one which depends only on its own weight to stand up. This type of retaining wall is huge.
Bearing, sliding and overturning forces need to be considered while designing a gravity retaining wall. It can be built from stone, concrete or even bricks.
A gravity wall’s cross section shape is affected by the usage of space in front of the wall, stability, technique of construction and desired appearance of the wall.
2. Pile Retaining Wall
This type of retaining wall includes piles that are driven so deep inside the earth that the pressure which typically tries to push the wall from above is held back.
Thus it makes use of counterforce to nullify the force from above and prevent it from tipping over.
The piled retaining walls offer great stiffness to retaining elements which bear big excavation depths with almost no problem to structures or properties around.
3. Cantilever Retaining Wall
Cantilever retaining walls are built from reinforced concrete. It comprises of a thin stem as well as base slab.
The base is split into two components viz. the heel and the toe. The part under the backfill is called the heel.
A cantilever wall can be built with much less concrete than other retaining walls however a very careful design and construction are required.
It’s often cost-effective till 25 feet in height. It can be produced on the site or even can be precast in a factory.
4. Anchored Retaining Wall
When retaining walls are high, cable wires or rods are installed deep sideward into the earth and then ends are filled with concrete. This offers an anchor. These are also called tiebacks.
They are useful when a thinner retaining wall is required or you’ve a limited space so that you cannot install other kinds of retaining walls. Loose soil over solid rocks can be effectively managed by anchored retaining walls.

Factors to Consider
Many other factors are to be considered while constructing a retaining wall. These include materials to use and type of wall.
For example, a simple-looking 4-foot high and 15-metre long retaining wall could hold back as much as 20 tons of soil, whereas another retaining wall of the same length but 8 feet of height could hold back 160 tons of soil.
This means that retaining walls hold an enormous amount of force that could otherwise destroy your property.
Other important factors to consider are slope of the land above and below the retaining wall, the space in which construction can be done, type of soil the retaining wall will hold back and the utility lines that may come in the way of the construction.
If you neglect any of these factors, the wall may bulge, crack and/or lean, thus wasting all your efforts and money.
