Gabion Retaining Wall: Facts You Should Know
Gabion walls are a type of retaining wall that uses large, metal cages filled with rocks or other heavy materials to provide support.
These walls are often used in situations where traditional concrete or wood walls would not be strong enough, such as on slopes or in areas prone to earthquakes.
Gabion retaining walls are usually made from galvanized steel, which makes them resistant to rust and weathering.
The metal cages are filled with rocks or other heavy materials, and then the cages are stacked on top of each other to create the wall.
The rocks or other materials help to hold the wall in place and provide support.
Gabion walls can be very effective at retaining soil and preventing erosion, but they are not always the most aesthetically pleasing.
Gabion Retaining Wall Facts You Should Know
Here are some important facts about gabion walls that you should know:
How to design a gabion retaining wall step by step
Step One: Determine the length and height of the wall.
Step Two: Choose the type of wire mesh.
Step Three: Calculate the amount of stone needed.
Step Four: Prepare the base for the wall.
Step Five: Fill the gabions with stone.
Step Six: Finish the wall by adding a cap or backfill.
How to build a gabion retaining wall
1. Excavate the area where the retaining wall will be built.
When excavation for a retaining wall is underway, there are a few things to keep in mind.
The first is the depth of the excavation. It is important to excavate to the correct depth, as this will determine the stability of the retaining wall.
The second thing to keep in mind is the width of the excavation. This is important because the width will determine the amount of material that will be needed to build the retaining wall.
The last thing to keep in mind is the type of soil that is being excavated. Different types of soil will require different methods of excavation.
2. Install the first layer of gabion baskets at the base of the excavation.
After the excavated area has been compacted, the first layer of gabion baskets is installed.
The baskets are filled with rocks and secured with wire. This layer will help to prevent erosion and provide support for the next layer of baskets.
3. Fill the gabion baskets with rocks or gravel
Make sure that the rocks or gravel you use are dry. Fill the gabion baskets with rocks or gravel to within about four inches of the top of the basket.
Use a shovel to level off the top of the rocks or gravel in the basket. If using rocks, make sure that they are not too big or they will not fit well in the basket.
Compact the rocks or gravel in the basket by tamping them down with your hand or a tool. Use wire cutters to trim any excess wire.
4. Install the second layer of gabion baskets on top of the first layer.
Unroll the second layer of gabion baskets on top of the first layer.
Place the baskets so that they overlap by at least 6 inches.
Secure the baskets to the ground with wire ties or similar.
Next, add the second layer of baskets on top of the first layer.
Once the second layer is in place, fill it with rocks like you did the first layer.
Finally, check that the entire structure is stable and secure.
5. Fill the second layer of gabion baskets with rocks or gravel.
Fill the second layer of gabion baskets with rocks or gravel.
Use a variety of rocks or gravel to fill the second layer of gabion baskets, depending on what look you’re going for.
Choose rocks or gravel of a similar size for the second layer of gabion baskets to create a more uniform look.
Check the rocks or gravel for stability.
Use a tarp to cover the gabion baskets.
6. Adding Layers
To get a fence heights taller than 3′, you should stack multiple baskets on top of each other.
This is because most baskets are only around 3′ tall. By stacking multiple baskets, you can increase the height of your fence.
Packing the lower basket with rocks is the first step in assembling the second layer. The wire closes its lid and then assembles the second layer on top.
A two-layered rock wall is a great way to add interest and beauty to your home. To create a two-layered rock wall, start by choosing the best-looking rocks for the face of the wall.
Then, fill in the center of the wall with less attractive fill rocks. This will create a sturdy, two-layered rock wall that will be sure to impress your neighbors.

Gabion walls are made of wire mesh filled with rocks, and retaining walls are made of solid material such as concrete.
Both types of walls can be used to support soil, but gabion walls are more permeable while retaining walls are more water-resistant.
Do I need a foundation for a gabion?
Gabions can be used without a foundation, but they will be less stable. If you are using them for decorative purposes, you may not need a foundation.
If you are using them for functional purposes, such as to support a wall or to prevent erosion, you will need a foundation.

How do I stop my gabions from bulging?
Gabions can sometimes bulge, which can be caused by a number of factors. The most common cause of bulging is when the gabion is not properly filled.
If the gabion is not filled with enough rocks or other materials, it can cause the gabion to bulge.
Another common cause of bulging is when the gabion is not properly supported. If the gabion is not supported properly, it can cause the gabion to bulge.
There are a few different ways that you can stop your gabions from bulging. The first is to make sure that the baskets are filled evenly.
If one side of the basket is heavier than the other, it can cause the basket to bulge. Another way to prevent bulging is to use a stronger material for the basket.
This will help to distribute the weight more evenly and prevent the basket from bulging.
Does a gabion wall need drainage?
Yes, a gabion wall needs drainage. The purpose of a gabion is to control erosion by allowing water to pass through it.
If there is no drainage, then the water will build up and eventually wash the gabion away.
How deep should a gabion retaining wall be?
A gabion retaining wall should be at least 2 feet deep and can be as deep as 4 feet. The depth of the wall will depend on the height of the wall and the soil type.
For example, if the wall is 4 feet high, the gabion should be at least 2 feet deep. If the soil is sandy, the gabion should be 3 to 4 feet deep.
