Foundations Guide

To Do Explanation

Step 1 – Survey


Have a civil engineer to Identify the area that the wall should be placed

Step 2 – Excavate

Regulations state that retaining walls should start at 500mm below ground but smaller walls are often placed at ground level.

Step 3 – Add Basecourse

Add a layer of Type 1 basecourse made up of crushed Granite Limestone, Basalt or Gritstone.

1m high = 100mm bascourse
3m high = 200mm basecourse
3m high + = 300mm basecourse

Step 4 – Compact Basecourse

Use a plate compactor to compact the basecourse

Step 5 – Geotextile

Cover the back of the gabions with a geotextile or weed mat to prevent soil and earth clogging up the gabions.
Step 6 – Concrete Foundation (If Required)

Most gabion walls do not require a foundation.

If you have a large amount of groundwater or the soil that you are placing the gabions is weak consult a Civil Engineer

They can perform a Scala Penetrometer foundation test to accurately measure the strength of the soil.

Stability Guide

To Do Explanation

2:1 Ratio

The height of the retaining wall should not be more than double the size of the base.

6 Degree Slope

The wall should be on a 6-degree slope.

It’s possible to have a straight wall but they need to be thicker

Base Width

The wider the base the lower the pressure on the soil. Spreading the load in this way allows for the wall to be placed on weaker soils.
  If in doubt consult Civil Engineer


Drainage Guide

Diagram Explanation

Gabions are porous allowing water to run through and prevent pressure build-up that can cause other types of retaining walls to collapse.

When installing the gabions ensure that a geotextile (commercial jobs) or a weed mat (residential jobs) is covering the back of the gabions. This will stop clay and thicker earth clogging up the gabions and preventing water from getting through.


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.

What is a gabion wall?

A popular and economical type of retaining wall. Made of large metal cages filled with stone, they can be stacked on top of each other to prevent earth from falling into unwanted areas.

How long does a gabion wall last?

In normal environmental conditions you can expect 50 to 100 years if the gabions meet the British Manufacturing standards for abrasion (EN 60229:2008) and corrosion (BS EN 10244-2:2009).

How expensive are gabion walls compared to other options?

Yes, they are cheaper than most other construction materials such as concrete that might be used for retaining walls. Gabions 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.

In the UK there are also many quarries that can deliver stone fill to you. You can Google ‘Quarry in [INSERT LOCATION]’ and you will find someone who can help. Alternatively, please get in touch and we would be happy to send you contact details of a quarry near you.

Stones are heavy and cost a lot to transport so it is much more economical for our customers to use local stones where possible.
