How to Make Gabion Pillars
Download ArticleBelow you will find a step by step guide on how to make gabion pillars.
- Difficulty level: Medium
- Tools Required: Shovel, Spray Paint (optional), Plate Compactor/Spade, Protective Gloves
- Materials Required: Gabion, Gabion Stone, Helicals/Tying wire, Gravel/Concrete, Support Posts
Step 1) Mark the Location
- Begin by marking the desired location for your wall using spray paint, stones, or alternative materials.
- Indicate the perimeter where you intend to build the wall with these markers.
Step 2) Dig the Base
- Dig until the earth is solid beneath.
Step 3) Install Support Posts
- Insert a support pole into the gabion, either inside or outside.
- The pole’s depth should be one-third the height of the gabion column.
- Use wooden or metal poles, and seal the top if hollow to prevent water damage.
Step 4) Add Basecourse
- Apply a layer of gravel or basecourse over the soil, following these guidelines:
- For a 1m high pillar, use a 10cm layer of gravel.
- For a 2m high pillar, apply a 20cm layer of gravel.
- For a 3m high pillar, add a 30cm layer of gravel.
Step 5) Concrete Foundation (If Required)
- For low-level or wide gabion columns, no foundation is needed.
- For taller or narrower ones, a concrete foundation can provide extra stability.
- Aim for a depth of 1/3 the column’s height and consider embedding support posts for added strength.
Step 6) Compact
- You can effectively compact the basecourse by using either a plate compactor or a spade, ensuring thorough consolidation of the material for optimal stability and durability.
Step 7) Install Baskets
- Position the gabion cages either onto or between the support posts.
Step 8) Fill the Gabions
- Complete the columns by incorporating helicals into the structure, ensuring their proper placement, and then seal the lids securely to finalize the construction process.
Step 9) Make up the Height
- When assembling 2 baskets for height adjustment:
- Attach helicals on three sides to link the second cage with the first.
- Proceed to fill the top basket as well.
TIPS AND TRICKS
- Use spray paint or stones to mark the location of your gabion pillars clearly. This will help ensure precise placement and alignment.
- When digging the base, make sure you reach solid earth to provide a stable foundation. This is crucial for the stability of the pillars.
- When installing support posts, ensure they are inserted to a depth of one-third the height of the gabion column. Sealing the tops of hollow poles prevents water damage and extends the life of the posts.
- Follow the recommended gravel layer thickness based on the height of your pillar. This ensures adequate support and prevents shifting.
- Use a plate compactor or a spade to compact the basecourse material thoroughly. This step is essential for the stability and durability of your gabion pillars
