Foundations Guide

To DoExplanation
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. Smaller constructions 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 cages with a geotextile or weed mat to prevent soil and earth clogging up behind.
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 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 DoExplanation
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

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

FAQs

What is a Retaining Wall?

They are a structure that is designed to keep earth within the desired area. Often built to prevent soil from sloping into unwanted areas such as motorways.

What is a garden gabion wall?

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

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.

Where do I get the stone?

In the UK there are 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 to 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 buy stone fill from a local quarry.
