Safe in post tension slab

[Green Bullet]

i'm very early in the construction process of a new home. i am going to buy a new safe and want to bolt it down in the garage. The foundation will be post tension. I was thinking about having hte builder pour an extra 4 " step in a section of the garage so i don't have to worry about drilling into the cable. Has anyone done anything like this? Any concerns or considerations or key learnings to share?

Make a map of the cables during construction and don't drill there

Or have them put the anchors in when they pour the floor. You might want it raised a bit for when you hose out you garage.

Building a pad for the safe to sit on is a good idea, you dont have to worry about hitting a cable or a flooded garage. You can place the safe where you want it not where the cables dictate its location.

metal detector should locate them when ready or a map is smart to.

Post tension is going to be a nightmare if you have future ideas for addititions or remodeling. I'm a concrete cutter, so just say'in.

Majority of post tension cables are usually 4" below finished floor and you still got room to drill a 3" deep hole and be fine. I recommend you use a 1/2" Simpson titen bolt so it's easy to uninstall later and grabs better than a red head anchor bolt

 

You can also pull lay out off the 2 closest corners you want the safe and notate the layout of the cables so you know where they are after you pour the slab and stretch , cut the cables and patch the stem at your slab

 

You can instal j bolts prior to pouring too but you will want to make a good template for your j bolts because it can be tough to get those bolts perfect so they line up with the safe holes.

 

And what most people don't know if you actually hit a cable it's not as bad as most people think. My framing crews have hit them multiple times while installing titens and anchor bolts for interior hold downs that required a embedment of more than 4" deep. The slab won't rip up even if the cables are already stretched . You will also be able to feel the difference in the rotor hammer if you hit a cable

Use the Simpson titan bolts as mentioned. 3" bolts will be plenty of grab. If you hit a able you will probably know it. I have hit rebar many times, and you always know when you hit it.

Most safe companys have a metal detector or a camera of some sort to locate post tension cables if you have them do it for you

Do they make an underground safe that you can hide from the libatard commies when they come for your guns.

There you go Mr Bullet. A perfect time to get a real safe installed in your house.

I think the key word was IN. Why not put the safe in the house out of sight. Instead of a hot garage in full view?
