To ensure stability, freestanding walls should not exceed 2:1
Customer Examples
Example 1 : H97.5cm x D97.5cm
Example 2: H1.35 x D67.5cm
Exceeds 1.5m or 2:1 Ratio
An internal support post is required if the wall height is exceeds 2:1 ratio or 1.5m height
How To
The strength of the post will depend on the height and weight of the wall. For medium sized walls use the equivelent of a scaffolding post
The posts should reach a minimum of 1.5m from the top
The post should be sunk into the ground approx 1/3 the height of the wall
Attach the support post to the gabion with bracing wire
If your pole is hollow, you will need to plug the gap at the top to prevent water from entering.
Set the post into concrete
Customer Examples
Example 1: H5m x D2m
Example 2: H3m x D1m
Example 3: H3m x D1m
Example 4: H2.6m x D1m
Foundation
Up to 1.5m height
Remove softer top soils until you get to firmer subsoil
Replace with 10-30 cm of type 1 basecourse
Compact the basecourse
Most low-level and/or wide columns do not usually require a foundation. If your column is 1m+ or narrow you may need a concrete foundation for added stability
1.5m+ height
Foundations should be 500mm below ground to prevent slipping.
Add a 30-50cm layer of type 1 basecourse
Compact the basecourse using a plate compactor
Configuration
As long as the cages are installed next to each other and they are attached securely using helicals or tying wire you can use different configurations

FAQs
What is a Retaining Wall?
They are a structure designed to keep earth within the desired area. Often built to prevent soil from sloping into unwanted areas such as motorways.
How expensive are they compared to other options?
They are cheaper than most other construction materials such as concrete that might be used for retaining earth in the same way. They are also very easy to use reducing the need for pay for extra manpower.
What depth should the structure have?
If it’s going to be freestanding, the depth should be at least half of the overall height in order to keep it stable. If it’s going to be reinforced with metal frames for example, you can get away with a smaller depth.
