We have a retaining wall that over the last 2-3 years has sunken quite a bit. The entire wall is approximately 40' long and runs east/west. In the middle of this wall, as portion has sunken to the south, towards the flower bed that it contains. This wall runs a long an east/west slope and probably drops off roughly 4' from the beginning on the east side to the west side.
**The PROBLEM is that the entire wall was put in using an adhesive to hold the blocks together. Does anyone know of any sort of material that can be applied to break up the adhesive so that I can get the blocks apart? It was put in approximately 8 years ago and just started to sag in the last 2 years.
