Re-bar placement

[Monkey Radio]

I am getting ready for the pour of my slab. I am wondering if there is consideration for re-bar under a lift. I am concerned with when I go to roto hammer for the anchors. I am planing on doing two 4x4 squares. The re-bar is being placed on a2x2 grid. The lift is going to be Bendpac XPR-10a. Any help would greatly appreciated.

Plan ahead and you should be able to mark out where the lift is going to be. You can get all the specs online so you'll know the bottom plate size and hole pattern. This what I'm doing right now. I'm also getting ready to pour cement in the couple of weeks.

There are "re-bar eater" drill bits available if you were to hit one. They are expensive but work well.

Should I have the rebar go through the base or just close?

Since I knew exactly where the lift post would be located (Chose a model, found a photo of the base online, made a template and measured my vehicles/garage many times), then I criss-crossed the re-bar directly underneath it allowing 3-4" of possible relocation in any direction for final placement.

Note the center squares are more open than the rest:

Verifying measurements after the lift arrived for column placement:

Note the marks on the floor to help with the final placement:

I had the advantage of an existing structure that allowed me to pre-test my vehicles so I could determine the exact location to place the lift. It worked out perfectly.

Rebar is not needed. (Structurally, it really doesn't do anything for you.) This is confirmed by the FAQ on BenPak's web site. The only thing reinforcing does on a slab-on-grade is cut down on shrinkage cracking. If you use this type of reinforcing, it should be placed in the middle of the slab to be effective. If you use a regular mesh, you'll have no problem drilling through it.

I am planing on doing two 4x4 squares.

These pads are not big enough and could pull right out if the lift were to see tipping forces. You might call BendPak and see what they require as the minimum pad size for their 2 post lifts. (I don't believe they give that information on their web site.)

You could use J-bolts ( the ones used to bolt down your walls), put them in in before you pour. Use a piece of plywood as a template for the bolts. Like the bolts you at the base of a sheel column.
