I am a sub that has been contracted to build a 170' long retaining wall that at its highest will be about 12 feet. the wall is going to go into a slope that is at best 35 degrees and at its worst about 45-50 degrees. excavation starts tomorrow, blocks (anchor product) arrive wednesday. this is a first for me, so I am bringing a friend in from atlanta to help. I would like to post pics here when its done, just gotta figger out how to do it. any advice or suggestions?
