Yeah we're actually going to have to repair/replace our retaining wall too. :( The large granite rocks looked alright when it was built around 7ish years ago, but between the critters digging in it (had a couple bad years with voles) and water erosion, it is falling apart in many locations, and my weak efforts to spot repair it haven't worked well. I'm probably going to be looking for quotes to rebuild it properly, but with some sort of cement this time. I'm sure that'll be cheap too. :S Best case scenario, maybe I could figure out how to both at the same time.
