Dear all,

I had an interesting conversation about this with an engineer. You can 
convert loading per square metre into kPa quite easily (there are lots of 
converters online if you want to try).

If the gabion is 1.7 metric tonnes (1700kgs) per m3 that converts to 16.7kPa 
per metre height of gabion. That ground pressure is between the pressure 
exerted by a quad bike (14kPa) and a standing human (55kPa). So, when 
considering static loading, I don't think that building stone-filled gabions 
would cause serious ground compaction.

Lady-boy mud wrestling aside, isn’t the load spreading idea with cellular 
confinement systems based on passing point loads e.g. stilettos, rather 
than static loads already spread in a wire basket?
The CCS solution isn’t a one-stop-shop. The details are key, as suggested 
by others:
soil type
ground conditions
water table
root distribution
foundations
size of gabion

The baskets are generally about 0.5m wide and 1-2m long.
In any case the fill is typically about 1400-1700kgs per m3 depending on 
material used.
