help with lift footings

[hrtatack1]

Hi Guys,

I am setting up my new shop on a not so good concrete floor (cracked floor). At the moment I cannot afford to pour a new floor, and I would like to install/pour footings for safety. I am on a tight budget and have to do it myself.

I am a mechanic by trade, and know nothing at all about how to install a footing. I am thinking it cant be that hard to do.

I have access to a jackhammer.

Does anyone have a step by step way to do this? Once again, I would need EVERY step...including making sure the footings are level.

The lift is a 10,000lb rated 2 post lift. The brace for the lift goes across the top....open span across the bottom.


Thanks in advance for the help.

Pete

I just realized I posted this in the wrong forum. It is in the floor section now.

Sorry about that

Can you post a picture of your slab where you are putting the lift? There are some good threads on this site for pouring renovation pads, but the state of your existing floor will dictate what needs to be done.

I have done this on 2 lifts thats were replaced. We had to do it because there were to many holes in the wrong place so we just replaced the concrete.

Figure out where you are going to put the lift. WHen I did it I cut out the concrete in a 4x4 foot square on both sides. jack hammer it up and make sure you are down at least 4-5 inches. More is better. I dug down 8 inches.

Cut the old concrete at an angle so the new concrete will go under the old if you can. It will keep it from pulling up. I also drilled into the old concrete and put in pieces of 1/2 rebar sticking out to tie the old and new concrete together.

When you pour the concrete use a 4000 psi mix. I also paid a piece of re-mesh in each footing. Make sure that it is level and that both pads are the same height. My floor was level so this wasn't a problem for me.

Keep it wet for about a week. Wait a few weeks before you drill it or put anything heavy on it.
