Rock armour
Rock armour
(OP)
I need a detail for rock armouring for river bank stabilisation - notionally using 1.5-2ton flat faced boulders. Max. bank height is about 1.5-2m.
Do I need to backfill the rock armour with a particular grade of stone to avoid washout?
Any help appreciated (or ideally a nice dwg I can pass on to the contaractor...)
Cheers
Kyle

Some years ago, when I was a resident engineer, we placed 1000's of tons of armor without backfill.
You might want to try calling CONTECH - earth stabilization unit, www.contech-cpi.com, they have a number of alternatives to armor stone that are cost-effective, and environmentally friendly. I don't work for them but I met with some of their reps yesterday to learn about their products. They said that armor has fallen out of favor with some regulatory agencies.
