How to install gabion retaining wall?

Installing a gabion retaining wall is a straightforward process if done correctly. Here are the steps to guide you through:

1. Planning and Design: Start by deciding where you want the wall and how high it needs to be. Measure the area and create a plan that outlines the dimensions and the number of gabions required.
2. Gather Materials: You’ll need gabion baskets, rocks or concrete pieces for filling, landscape fabric, and tools such as a shovel, a level, and gloves.
3. Prepare the Site: Clear the area where the gabion wall will be placed. Remove grass, weeds, and debris to create a clean surface. Ensure the ground is level to provide a stable base for the wall.
4. Excavate the Foundation: Dig a trench for the base of the wall. The trench should be about 4 to 6 inches deep to ensure stability. Add a layer of gravel at the bottom to enhance drainage.
5. Lay Landscape Fabric: Place landscape fabric along the trench to prevent soil from washing through the gaps in the stones and to promote drainage.
6. Assemble Gabion Baskets: Follow the manufacturer’s instructions to assemble the gabion baskets. Ensure they are securely closed and free of defects.
7. Fill the Gabions: Start filling the gabion baskets with rocks or concrete. Use smaller stones at the back and larger stones at the front for stability and aesthetics. Fill each basket evenly and avoid large gaps.
8. Level the Gabions: After filling, use a level to check that each gabion is straight and level. Adjust as needed before securing them into place.
9. Stack and Secure: If your gabion wall is tall, stack the baskets appropriately, ensuring they are stable. Secure them together using wire ties.
10. Final Touches: Once the structure is complete, backfill around the baskets with soil and additional stones. This will help integrate the wall with the landscape and provide further support.
