    I'm not an expert by any means, but I reckon the chances your slab will be enough as is are pretty slim.

      how far apart would you normally put the posts? Turns out we are getting one at work. I am assuming a 150-200mm slab will be enough?
      .... because every driver experiences the destructive potential of the effortless surge of power available through the smallest of body movements.

        i reckon you're right too which is why i would like a pro to check it out so i know for sure. they might also say "yeah its possible if you do XYZ" which i have nfi about.

          How did you measure what you have? Kind hard to do generally other than just drilling a hole somewhere. I gave up pretty quickly trying to even figure it out. My place is modern enough it would be a waffle pod slab, so pretty much no chance.

          You place looks a bit older? 80s/90s perhaps. Don't know if they would have built it that much differently.

            I mean, it can be an option to cut out two pads, dig out, and pour some deeper concrete there. You'd have to be keen though

              place was built in 69 so should be a solidish slab. there are already a couple of holes in the slab so i stuck a bit of coat hanger wire down them and tried to measure where it hit the dirt.. not the most scientific method I know

                  They usually come with specified measurements. I'd work with around 3.5m total width, as that seems to be what most are when you look at the diagrams.

                    What I don't understand is that I can sit my car on 4 stands without worrying about the concrete but need proper footings for a hoist?

                      Pretty simple. When standing on 4 jack stands (or its wheels for that matter), the concrete is in compression and concrete is very good at compression i.e. not getting squashed.

                      Concrete is not very good in tension. As soon as you put a 2 post lift in the weight of the car will try and fold the posts at the base which is putting the concrete in tension. You're also talking about some weight to hold the posts down, which is not needed with 4 load points pushing straight down..

                      For the same reason, a 4 post lift doesn't need anything special.

                          Yep mine too. Have a bucket under it and top it up every month or so. And now the rams drop over a couple of days
