How to Stop Gabion Baskets Bulging

Below you will find different methods on how to stop gabion baskets bulging. 

• Experience Required: Low
• Tools Required: Protective gloves, Wire cutter, Pliers, Screwdriver
• Materials Required:  Corner ties, Tying wire

 

Introduction

• Bulging usually occurs when gabion baskets warp out of shape due to thin wire, increased force on the face or choosing the wrong shape of stones.
• This can be corrected by bracing the baskets with tying wire or by using corner ties.

 

Step 1) Start Filling 

• Start filling the basket with stones until you reach 1/3.
• Brace the gabions at 1/3 and 2/3 or at every 3rd hole vertically to prevent bulging.

 

Method A – Step 2) Make a Loop

• Cut a piece of tying wire just over twice the length of the basket.
• Make a loop from the back to the front and twist the ends together.

 

 Method A – Step 3) Twist the Loop

• Start twisting the loop around itself with a screwdriver or a flat stone.

 

Method A – Step 4) Twist Until Tensioned

• Twist until the wire is tight between the two sides of the gabion.

 

Method B – Step 2) Insert the Corner Tie

• Hook the corner tie onto the 4th wire from each corner (symmetrically on both sides).

 

Method B – Step 3) Lock the Tie into Place

• Twist the end of the hook around the corner tie.

 

Method B – Step 4) Twist the Other Hook

• Twist the other hook as well.
• Make several twists to ensure the tie is firmly anchored.

 

Method C – Step 2) Simple Tying Wire Method

• Use a piece of tying wire slightly longer than the gabion’s length and connect the facing sides.

 

Method C – Step 3) Form a Loop

• Form a loop and twist the end of the tying wire around itself until the cage is sufficiently tensioned.

 

Method C – Step 4) Finished Result

• This is a quicker and easier method that can speed up the process of bracing.
• We recommend using the first 2 methods for a more durable result.

 

Step 5) Repeat Steps

• After you completed bracing the first 1/3 of the gabion, add a new layer of stones until you reach the next 3rd.
• Repeat the steps of your preferred method.

 

Further Tips on How to Stop Gabion Baskets Bulging

• Depending on your project, choose a suitable wire thickness steel basket (min. 4mm).
• Choose interlocking rocks to achieve straight edge finish.
• Try to position the flat surfaces of rocks against the basket walls.
• Place the rocks manually in the cage to ensure straight edges and have a better control over organising the stones.

 

Warnings

• Don’t neglect the use of braces at 1/3 and 2/3 filling levels.
• Avoid using low-quality or thin wire baskets.
• Don’t forget about regular inspections and maintenance.
