Gabion Wall

[JeffMorris]

I am required to construct a staircase between an existing structure and a buried gas main, due to the construction of the adjacent structure half the area is in cut.

The designer has suggested a mass filled concrete structure (approx 22m3), would it be possible to use a gabion wall and infill behind it with compacted layers of suitable fill seperated by a geotextile?

Anyone have any experience of this technique.

gabion wall could be used, however it isn't particularly easy to walk on gabions. If this is to be used regularly, you might want to consider a shotcrete facing on the gabions to provide a better walking surface. Or you could backfill over the gabions with soil.

Although gabion walls are very attractive, they are also relatively expensive. If done correctly, it involves a good deal of hand labor by experienced laborers. If you have room, you might consider a modular block wall will backfill behind it or reinforced earth.

Gabions are a definite possibility. They solve any drainage issue that you may have as well. Shotcrete facings are, as noted above, doable., but then so are cast in place concrete risers or pavers infilled with rock dust placed on top of a fabric to hold the dust. The vertical faces can be disguised with creeping ivy or some other climbing vine. Modular walls such as Versalock are a good and attractive alternative and are easily taken apart and restored should access to the gas main be required. Think about compacted sand/cement or rock dust for the sub-base. Good-Luck R.A. Hassett, P.E.
