Alot of that is going to depend on when the thing was built and the kind of person it was built for. Our garage at camp is a full 6" thick with rebar and mesh to prevent cracking. My father-in-law just replaced his garage, I think the floor is 4" thick which was required by the city. The thing it replaced had maybe 2" thick but it was in 3 separate pieces.
I agree that you'd probably want footings though. -Curt Date: Mon, 9 Sep 2013 12:01:34 -0700 From: "Greg Fiorentino" <gf...@dslnorthwest.net> To: "'Mercedes Discussion List'" <mercedes@okiebenz.com> Subject: Re: [MBZ] Home garage lift Message-ID: <009901cead8f$011b54a0$0351fde0$@net> Content-Type: text/plain; charset="us-ascii" I have no expertise on the subject, but have some experience in drilling and installing anchors in concrete (about a year working as a steamfitter/rigger on a powerhouse). I installed some aluminum bars on the floor of my garage as positioners/stops for ramps. I was surprised to see that the concrete floor was not very substantial, less than an inch. Unless there is a substantially thick floor, I would think a better footing would be required. I would think a manufacturer of the lift could tell you what is required.
