Garage lift

[FC]

My slab was not reinforced, but it is 8" deep and made of 4000psi concrete. I also was OCD about keeping it wet during the curing process. Well, the first week (~90% cure). It will technically asymptotically cure for a bunch of years.

My slab is barely adequate for a two-post lift. It was poured in 1986 and most but not all of the holes had adequate depth for the anchors.

Everything I put on it is relatively light, though, and I have a cross-bar for the top of the lift posts that certainly helps a lot.

Are you sure that raising the ceiling height will be easy? It often takes ripping off the roof, replacing all the trusswork, etc, and putting a new roof back on. It won't necessarily take all that, but until you have someone that knows what they're doing take a look...

That’s what we had to do. But they were able to remove the existing trusses, extend the wall height, and then reinstall the same trusses.

I wonder if there are code differences from place to place that could have an impact? (dunno what code requirements are for that kind of thing here)

When I bought my house, one of the first things I did was pick up my concrete driveway and bag it for the garbage men to haul it away.

That probably influenced my decision to go overboard on the concrete for my garage floor - 24' x 28', 21 years old, no cracks. Oldies but goodies: Garage 1, Garage 2

You make a good point ...I’m going to have to ask my contractor who has done most of the work to my house to let me know his thoughts, then of course there is an easier solution, just get used to the 540 sitting outside.
