i have a RR retaining wall that goes from about 1' to 5' H over the length of about maybe 80' or more. There's a spot where an 8' tie on the bottom ( not sure what is below that one) is twisting and splitting and causing a few above to start now bowing out a bit. Is there a way to "jack up" the ones above it, cut it out and replace as like they would do in the old days with an old timber foundation log? This ret wall has drainage strips that run right along the bottom of it and then is a concrete deck for a pool and hot tub. There are dead whatever you call them holding the wall then it leads to my yard beyond that. Some top RR ties are going to be replaced but the rest are fine as they've been power washed and sealed every few years as well presides being pressure treated and dipped in whatever they use to treat these things. Because these ties are staggered it'd be a huge job replacing the whole thing. This is my idea unless anyone else has others I'd really appreciate it.
