I’m getting ready to move a gun safe and I want to secure it to my garage floor which is a standard cement floor. While I have zero water issues from outside, water and snow will slide off the vehicles and sometimes puddle a tad. As such, I was wondering if I could poor a second pad that was the dimensions of my safe on the floor such that it would be secure and stable? I would like to bolt the safe to the floor and I’m not sure if the new slab would be secure/stable if I did.

Thanks!

I put one on a 6 inch slab in basement.
Made a card board templet and put bolts in the mix.
Worked well but took three of us to lift that damn thing on the bolts

Not a concrete guy, but if I were to do something like that, I'd put concrete anchors in the existing floor (in a pattern to match the holes in the safe), screw in threaded rod long enough to extend above the intended new pour, and then form up and pour around the rods.

I would refrain from using something as permanent as concrete. Is the next home owner going to want an odd slab in the garage? Have you considered using something like a rubber mat or a treated wood frame? Just use longer anchor bolts as needed to drill down into the concrete below. Concrete is cold and without a thermal break/air gap you risk the potential for corrosion. Make sure the bottom of your safe is well painted, many have no paint on the bottom at all.

Myself, I built a 2x4 wood frame with 1/2 plywood and used leveler bolts on the corners to ensure I could get it dead level. Used extra long anchor bolts into the concrete.

Don't need to pour another pad of concrete. You can set it up on anything... pallette, blocks, wood sleepers, et. al. Just run your bolts through whatever you use to get it up off the floor. It won't have quite the shear strength to resist tipping but I doubt that's much of an issue with a big safe anyways.

This, use some plastic trex deck boards and bolt through them into the existing slab.

Thanks for the advice. Great solutions (as usual from SIGforum).

Yup, use Red Head expansion bolts and make sure they get at lease half way in to the slab.

You don't need a pad. Use the.redhead anchors as suggested. Before you begin use a level and see I the floor I pitched. It should be but you never know.
