Height & Loads

1.5m or Less & Low Loads
X – Engineer required

[insert image]

A retaining wall does not require an engineer’s calculation when it meets the following criteria

It is lower than 1.5m tall
It is retaining flat earth
It is not retaining heavy loads such as roads or buildings
The ground does not have a lot of groundwater

1.5m+ or Large Loads
Y – Engineer required

[insert image]

A retaining wall does require an engineer’s calculation when it meets the following criteria

It is taller than 1.5m
It is retaining sloped earth
It is retaining heavy loads such as roads or buildings
The ground has a lot of groundwater

Foudations

Basecourse

1.5m or less & low loads (i)

Remove softer top soils until you get to firmer subsoil
Replace with 10-30 cm of type 1 basecourse
Compact the basecourse

1.5m+ or large loads (i)

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

Stability

Shape

1.5m or less & low loads (i)

Can be built without the step, as long as the ground is flat and it is not retaining a large amount of weight, such as a road or buildings

1.5m+ or large loads (i)

Usually requires a stepped shape. The depth of the bottom row is half of the height.
Consult a Structural Engineer if you are planning a non-stepped shape

2:1 Ratio

1.5m or less or low loads (i)

The height should not be more than double the size of the base; otherwise, it will not be suitable for a retaining wall.

1.5m+ or large loads (i)

If you are planning to use a 2:1 ratio and your wall is over 1.5m, you will require a Structural Engineer to check the calculations

6 Degree Slope

1.5m or less or low loads

The wall should be on a 6-degree slope leaning into the earth to improve the strength and stop slipping.

1.5m+ or large loads (i)

The wall should be on a 6-degree slope leaning into the earth to improve the strength and stop slipping.

Drainage

Geotextile

1.5m or less or low loads

Cover the back of the cages with a geotextile or weed mat to prevent soil and earth clogging up behind.
Install a drainage pipe, then cover it with 10cm of gravel for drainage

1.5m+ or large loads

Cover the back of the cages with a geotextile to prevent soil and earth clogging up behind.
Install a drainage pipe, then cover the back of the wall with 20cm of gravel for drainage
The drainage gravel should be installed within 15cm of the top

To Do

Explanation

Up to 1.5m & 2:1 Ratio

To ensure stability, freestanding walls should not exceed 2:1

Customer Examples

Example 1 :H97.5cm x D97.cm
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

[image showing good connection + 2 most comment installations]

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

Customer Examples

Example 1 :H97.5cm x D97.cm
Example 2: H1.35 x D67.5cm
Example 1: H5m x D2m
Example 2:H3m x D1m
Example 3: H3m x D1m
Example 4: H2.6m x D1m

Basket Assembly

Gabions are delivered flat-packed with the sides, bottom, and lid clipped together. Upon arrival, the corners of the gabions should be attached to complete the assembly.

Corner Assembly Fitting
Using helicals	Helicals can be purchased separately. 4x helicals are required for assembly per gabion (one for each corner).PRO: looks uniform and quick to install CON: additional cost
Using tying wire	Tying wire is supplied with all gabion orders. PRO: it’s free CON: time of installation
Using CT35 clips	Gabion clips are available in bulk quantities. Advised for use by professionals PRO: discrete / hidden CON: requires a plier or electronic tool

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.

Where do I get the stone?

We supply stone suitable on this page.
