Place the second row of baskets on top of the first one and connect them together with helicals at the front.
Step 11 – Fill and Join
Fill the top baskets with rocks as well.
For added security, you can join the baskets with helicals from front to back. You may need to cut some of them to fit the depth of your wall.
Step 12 – Finished Project
Your 2m tall freestanding gabion wall is done!
Step 1 – Identify location
Use spray paint, stones or other materials to mark the location where you plan to construct your wall.
Step 2 – Dig
Regulations state that retaining walls should start at 50cm below ground. However, Gabion walls lower than 2m are often placed directly on the ground or at a shallower depth. Digging between 20cm-50cm or until the ground is firm ground, such as clay instead of the topsoil should be adequate.
Step 3 – 6 Degree Slope
If you are retaining a lot of earth, the hole should have a 6-degree slope leaning back. If you are retaining a small amount of earth, such as a garden bed or the wall is mostly decorative, you can maintain an upright edge instead of a 6 degree slope if you prefer.
Step 4 – Add Gravel
Add a 20cm layer of gravel or basecourse on top of the soil.
Step 5 – Compact Gravel
Walk and stomp on the gravel to make it compact
Optional – Concrete Foundation (If Required)
Most low-level gabion walls do not require a foundation but if you have a large amount of groundwater or the soil is weak it may be needed.
Step 6 – Geotextile
Cover the back of the gabion baskets with a geotextile or weed mat to prevent soil and earth clogging up behind the wall.
Step 7 – Unfold the Baskets
Unfold and lift up the sides of the baskets.
Step 8 – Join the Cages
Assemble and attach the baskets together with the helicals included in the kit.
