IMO no, I believe the common 3" requirement deals with the variations in the subsurface elevation and stability during a pour. I say keep it at 3".
Depending on the size of the job. We have found it beneficial to pour a mud slab using lean concrete to form a stable level base to build off...
>The 2014 CRSI cantilever retaining wall design guide references ACI 318-14 and they also use all the typical provisions from the various beam/slab sections of ACI 318-14.
OK, good to know. Thanks
Yes, Thanks.
I'm familiar with that reference. When I use it it sends me to either Beams or Slabs in 318-14. I'm trying to find if or how the 14 code requires it for walls.
I'm looking for a few references in 318-14 that I used to follow for retaining walls in older versions of the code. I realize the code has gone to a more member specific layout but I would think these items would still pertain. My application is a cantilevered retaining wall.
