what is the best way to attack moving a retaining wall? I have a keystone compac wall that goes from about 2' to 5' back down to 2' over a 100' span. The wall needs to be moved out another 5-6' from where it currently is. The block from the original wall will be reused for the new one. I can get a tractor in from each end to dig for the first course, however that is basically the only access i'll have. What is the best way to safely move this? Should i lay my first course the whole way across? Since i'll be adding 1 extra layer than is there now to maintain the same finished height, then build up from one end working my way across back-filling with stone as i go? This is the only way i think would work that i'll be able to get out all the blocks from the original wall safely. Also would you fill the entire 5-6' with crushed stone since there is already stone 1-2' behind the existing wall? That would be a lot of money in stone it seems. Thanks for the help guys, sorry if my thoughts are a little jumbled, it's been a long day and i've never moved or replaced an existing one this size.....built new, but never moved.
