Did we hire Carol to pump you up?
Sorry but all you've done is applied a bunch of weight to the bottom of your safe. It's not secured to the floor in any way shape or form. Lets not forget that concrete shrinks and will dislocate the adhesion to the slab all by itself over time. You didn't even follow Sika's instruction of a 1/16" fractured surface for adhesion properties. General that needed some mules to direct eh? I doubt that would even work after everything cured and I slam that make shift slab with a sledge a few times jarring my teeth. Then apply a nice 5 ft. pry bar on those corner studs at top of safe (wow the leverage baby) lifting the slab just enough to slide a wedge under it or just drive the steel wedge from the beginning and forget jarring my teeth.
Sledge again, timber.
But in all seriousness I would just bring a saw and be inside in less than 3 minutes drinking your beer in the fridge.
Thanks for the entertainment, that why I love Calguns.
