How is a New Day shelter anchored to the slab?

How shelter is anchored to slabNew Day uses only HILTI anchors in either the Kwik Bolt lll or the Hilti Kwik HUS Screw Anchor.  As it turns out, we are called upon often to move a New Day safe room from one location to another, and the fact that the Hilti HUS anchors are removable makes this anchor our top choice.

Why can a tornado pick up cars but not this?

Annular Anchorage PatternIf a car is swept out of a garage, the slab beneath it never moves.  The New Day shelter grabs like cat claws into the slab so it also never moves.  Its steel is ten times as thick as that of a car body.  Remember, vehicles are meant to be mobile, not immobile like a safe room.

Huge trees topple in storms, so why shouldn't this?

Trees topple when this won't.Winds speeds in a storm are considered to be greatest at perhaps 30' above ground level.  And fully-fledged trees have three things working against them that this shelter does not have: 1) Huge surface area, which equates to high drag, 2) Moving center of gravity and 3) High leverage.  BTW, the 3D surface area of a single leaf is much more than one might expect due to its fractal geometry.  On the other hand, a domed cylinder has absolutely minimal surface area per volume.

Are they "bullet-proof"?

Resistant to bullets.Yes, to IAC Level III or greater.  An M4 Carbine made these dents when shot from 30 yards into sample wall and door panels.
