Installing gabions & mattresses in winter
Installing gabions & mattresses in winter
(OP)
Does anyone have any experience of installing gabions and renomattresses in winter, in frozen ground, for riverbank erosion protection? I know the US Army COE does not permit this. In my opinion, preparation of the banks would be difficult, and maybe there would be uneven settlement in the spring thaw. I'm in a part of Russia where the winter is 7 months long, and where there are restrictions on working in or near rivers in the thaw period. I also have an inept contractor, whose previous mattress installations have been rejected my myself. Any responses would be appreciated

Also recommend using granular filter instead of geotextile if placing on ground which may settle

The installation of PVC coated wire mesh gabion structures is very difficult.
As the double twist wire gabions are flexible, post installation ground movements will be accommodated by the structure.
Your best course of action is to replace the Contractor as unqualified. Almost anything is possible with a competent Contractor. Most Contractors (and Engineers) fail to understand that while gabions are fairly simple structures, they are at all times engineered structures.
If you are working with Maccaferri Russia, have them consult with Maccaferri Canada for winter installation suggestions.
