Re: Installing a Safe

DON'T JUST DRILL...ESPECIALLY IF YOU HIT A HARD SPOT!!!

It may not just be rebar you hit. Many homes are built with a post tensioned slab. The tendons you have a chance of hitting are streesed to around 30K psi. If you cut a tendon, it can quite literally go shooting out of the side of your house several hundred feet if the conditions are right.

Look for grout pockets around the side of your foundation along the perimeter. If you see them, do your self a favor and rent a metal detector to locate the tendons so you don't cut through one accidentally. Most post tensioned slabs in my area are only 4" so the tendons are only around 2" down.

Check before you drill.
