I'm working on a proposal that will require us to build a retaining wall from concrete masonry units, and I'm hoping I can get some help from the bright minds of the GTX membership on a few questions.
Here they are:
With no setback, I'm concerned about the mass of the wall being able to hold back earth. With that in mind, what size block should I use? Also, is there something I can use as a tieback for this kind of wall, similar to deadmen for a timber wall or geogrid for an SRW wall?
For reference, there will be two tiered walls, 3-4' in height each, with at least 10' separating them.
Thanks in advance.
