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. |
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 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 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.
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.
