The installation of gabions is low construction cost
Gabion are used for permanent erosion control in channels, streambanks, spillways and stable slopes from surficial erosion. The stone confinement within the units allows for higher shear stress resistance than the riprap. Soil bioengineering techniques can be used to promote vegetation in the gabion to provide enhanced shear resistance. Some other applications include highway embankments, channel linings, slopes and embankments and railway cuttings.
Low Construction Cost
The installation of gabions is very cost effective. The mattresses are easy to construct requiring limited equipment, unskilled labor, minimal foundation preparation, no drainage provisions, and low cost stone fill generally provided by a local stone or rock supplier. Gabion & Reno mattress structures require very little if any maintenance and if designed and built properly can be a permanent structure.
