How to Make Gabion Steps

Below you will find a detailed guide on how to make gabion steps.


Step 1) Measure Up Your Area


  • Begin by examining the area where you plan to place the new steps.
  • Measure the length and width of your structure according to the available space.
  • Also, measure the total height (rise) to get an idea of how many steps you’ll need in total.


Step 2) Calculate Gabion Sizes


  • Sketch a plan for your stair following these guidelines: each step’s height (rise) should be around 15-22.5cm & each step’s depth (tread) should be around 30cm.

  • Calculate gabion sizes and quantity needed.
  • Remember to calculate how much stone you’ll need.


Step 3) Mark the Area


  • Mark the area with spray paint or strings.
  • Remember to add an extra 10cm on each side for proper alignment and stability.


Step 4) Create Foundation


  • Make sure the stair foundation is level for stability.
  • Also, incorporate a slight slope towards the front for drainage to prevent water from collecting.


Step 5) Add Basecourse


  • Add a layer of Type 1 gravel according to the height of the structure:

    • For 1m high stairs, use 10cm of basecourse.
    • For 2m high stairs, use 20cm of basecourse.
    • For stairs 3m high or taller, use 30cm of basecourse.


Step 6) Compact Basecourse


  • Use a plate compactor to compact the basecourse thoroughly, ensuring stability.


Step 7) Add Geotextile (Optional)


  • Line the bottom and sides of the structure with geotextile fabric to prevent soil erosion.


Step 8) Fold up Baskets


  • Fold up and secure the vertical corners of each basket with 2 cable ties: 1 at top and 1 at the bottom of the corner.


Step 9) Position the Baskets


  • Position the boxes starting with the largest one at the back and working towards the shortest one. 
  • Make sure to push the adjoining corners as close together as possible.
  • The lids should be folded upwards, make sure they’re not falling behind the baskets.


Step 10) Attach them Together


  • Secure the corners of the adjoining steps with a helical to prevent movement. 
  • The helical should connect the corners of two gabions.


Step 11) Trim Excess


  • Cut off the excess lengths of helical where needed.
  • Fold the ends of the helicals downwards with pliers.
  • Additionally, cut off any excess geotextile.


Step 12) Fill with Stones


  • Fill each gabion basket with the calculated amount of stones. 
  • Leave a slight gap at the top to allow space for the timber.


Step 13) Attach Timber Treads


  • Place a timber on top of the stones on both sides of the stair. Close and secure the lid with a piece of wire or cable ties. 
  • Position timber treads onto the lid and screw them to the timber under the wires. 
  • Repeat these steps until you complete the process.


Step 14) Check for Stability


  • Inspect the completed garden stairs and check for stability. 
  • Make any necessary adjustments to ensure safety and durability.



  • When considering how to build gabion steps, it’s advisable to opt for 5mm baskets over the 3mm and 4mm ones to prevent bulging, thus ensuring structural stability and strength.
  • To avoid water accumulation and any accidents, maintain a slight slope on step treads and plan drainage, especially for sloped garden stairs.
  • While deciding how to build garden steps, make sure to maintain consistent height, width, and, in the case of straight stairs, also depth, to avoid stumbles or falls.
