The retaining wall toe prevents the gabion wall
sliding forwards, the depth of the toe needs to increase as the wall gets bigger.
When building gabions on softer soils, both the depth of the toe and the size of
the base needs to be increased to spread the load over a wider area. An engineer's design will
consider the design limit
states and specify the dimensions
of the toe and base for your wall.
When the gabion retaining wall is subject to a
additional surcharges, from a driveway or other loads, the design
will most likely increase the depth of the gabions, to handle the higher expected
loads.
When constructing gabion retaining walls in
strongly acidic soils(PH over 5.5), the soil and the corrosive groundwater must
be separated from the gabion structure by using geotextile fabrics and a
properly designed drainage system.
For larger retaining walls and difficult sites, it is recommended that a soil investigation is undertaken and that the wall is designed by a qualified geotechnical engineer.
