How to Make a Curved Gabion Wall

Below you will find a step by step guide on how to make a curved gabion wall.

Experience Required: Medium
Tools Required: Shovel, Bolt Cutters, Spray Paint (optional), Tramper, Car Tire (or similar round object)
Materials Required: Gabion, Gabion Stone, Geotextile, Helicals / Tying wire, Braces, Gravel

Step 1) Walk the curve

Use a string attached to a bamboo stick and walk the it along the area where you would like to create a curved gabion wall.

Step 2) Mark the curve

Lay string along the planned curve for wall installation.
Position the string on the ground to delineate inner and outer sides.
Secure the string at intervals of 1 meter using rocks to keep it in place.

Step 3) Measure string

Place the string on the ground.
Utilize a measuring tape to determine the length of each string segment.

Step 4) Buy materials

Obtain cages to match the length of your inner curve.
Optimal lengths for cages are 45cm or 97.5cm for achieving the desired curve effect.
Longer cages are acceptable, but they may not produce as pronounced of a curve effect.

Step 5) Dig

Dig to a depth of 10cm, or until the soil is solid.
Gabion walls shorter than 1m can be placed directly on the ground, but for better stability, it’s advisable to set them on solid ground like clay rather than topsoil.

Step 6) Geotextile

Cover the soil with geotextile to inhibit weed growth beneath your structure once it’s installed.

Step 7) Add gravel or basecourse

Place a layer of gravel or basecourse over the geotextile.

Step 8) Compact gravel

Walk and stomp down on the gravel to compress it
Alternatively, you can use a tamper tool

Step 9) (Optional) Concrete foundation

Many basic installations don’t necessitate a foundation, however, in cases of excessive groundwater or poor soil quality, it might become necessary.

Step 10) Placing Base Panels

Position panels horizontally on the ground.
Ensure panels extend beyond the base of the curved wall.
Cover the entire length of the wall with these panels.

Step 11) Rolling panels into shape

Curve the side panels around a tire or another curved item.
Roll it repeatedly until it forms the desired circular shape.

Step 12) Adjust curve

If necessary, step on the panel post rolling to fine-tune the curve.

Step 13) Position Side Panels

Place the initial inner, outer, back, and front panels onto the base panels.
Ensure the corners of the panels are securely attached to maintain their position.
Consider adding rocks or posts for extra support during the installation process.

Step 14) Add braces

Add braces at every meter interval along the wall.
Place the braces around the midpoint of the structure’s height.
Enhance stability and minimize bulging by adding these braces.

Step 15) Cut the base

Cut the base panels to match the contour of the side panels.
Leave approximately 5-10cm surplus wire for folding back into the cage.

Step 16) Fold the base wires

Fold the additional 5-10cm of wires backward into the basket.
Ensure the fold loops over the top of the side panel mesh.

Step 17) Repeat Steps 7-12

Repeat steps 7-12 until you have completed your installation.

Step 18) Fill the cages

After positioning them, proceed to load the cages with gabion stone.
