I've never worked with concrete before, but I feel like this is a job I can tackle. I'll be installing a safe in the basement that has been known to take on water, so I want to put down a pad to raise it up 12 inches. Safe is 42X32. Should the pad be the same size or larger? Do I just bang together some 2x12s for the form and fill it? I'd appreciate any advice.

TIA,
John

2x12s and fill will work. Does the safe have wheels? If so I would make the pad a couple inches bigger at least to give some leeway so it doesn't roll off.
How heavy is the safe? Will you be able to lift it up on the pad?

A pressure treated wood platform would probably work fine and be easier to construct.

Safe is 1000 lbs. Will have the movers get it up it's not on wheels and it will be internally bolted down to the slab. I need the slab to be "part of the floor" as tipping over safes is often the first step in break ins. Planned on using rebar and epoxy for that.

Ayuh,.... No need for epoxy,.... use cement,....

Drill yer holes, pound in yer rebar, 'n pour yer block,...
Wigglin' the rebar as ya fill the form will allow the snot to flow into the rebar holes, lockin' everything together,...
Whether tappin' the form with a hammer, or usin' a vibrator, the more ya settle the concrete, the stronger it is,....
