thanks I will! The shims will hold indefinetly. I shim up entire 6 plexes 2 or more inches in the air (to compensate for bad concrete finishers) The shims are fine. They compress quite a bit but you have to think of the weight of a 3 story 6 plex. After I build the building, crews come in and grout under the walls to permenently support it. (just because if I don't say it some one will make a comment
)
