– 1x or 2x baskets delivered for each pillar that you have ordered (depending on the height)
– Helicals will be included so you can attach the corners and lids for all baskets in your order. Helicals are 1m long so if your baskets are under 1m, you will need to cut the helicals to size with a hacksaw or wire cutters
No – these commercial grade cages can be filled with any shape of stone without bulging
Can be filled with crushed concrete
Can be filled with rounded rocks
If the columns are being installed in a public location or they are large and heavy, please consult an engineer to ensure your design is stable. Your engineer’s design and instructions should take priority over the instructions below.
Step 1 – Identify location
Mark the location where you plan to construct your column.
Step 2 – Dig
Dig until the ground is firm.
Step 3 – Install Support Posts
Add a metal support pole which can be placed inside of the basket or supporting the outside if you prefer. The depth of the support post should be around 1/3 the height of the gabion column.
You can use wooden or metal poles such as a scaffolding post. If your pole is hollow, you will need to plug the gap at the top to prevent water from entering.
Step 5 – Add Basecourse
Add a layer of gravel or basecourse on top of the soil as follows:
1m high column = 10cm gravel
2m high column = 20cm gravel
3m high column = 30cm gravel
This step is not required if you are going to add a concrete foundation.
Step 4 – Concrete Foundation (If Required)
Most low-level and/or wide columns do not usually require a foundation. If your column is 1m+ or narrow you may need a concrete foundation for added stability
The depth of the foundation should be around 1/3 the height of the pillar. You can set the support posts into the concrete foundation.
Step 6 – Compact
Compact the basecourse using a plate compactor or a spade.
