Safe-room Specifications:
Foundation:
Our footings are 18 inches in depth by 20 inches in width
and are required for our safe-rooms. We position 5/8
inch rebar in the footing vertically on one foot centers,
two in the corners that rise out of the footing two feet or
more into the wall voids which will soon be filled with
concrete. By doing this our walls are tied to the a
very large footing, buried 20 inches in the earth.

Wall Detail:
Our walls consist of the 6 inch concrete straight wall block
and 90 degree corners. We stack the block up to 8 feet
and place 5/8 inch rebar vertically, on one foot centers and
every course of the block horizontally as we stack. You are
surrounded by a fortress of steel and concrete to protect
you and your family.

Safe-Room Door:
Our door system meets FEMA’s rigid standards of wind load
speeds of up the 250 mph and missile impact of 100 mph or
better. The frame is made of 14 gauge commercial
quality, carbon steel that is enveloped in concrete during
the pour phase.
The door is also 14 gauge reinforced steel weighing about
150 lbs. A 2068 comes standard, however, a 3068 is available
upon request. All doors have
Schlage hardware with three deadbolt locks and one
pass-through on the open side and three heavy duty hinge
sets on the fixed side. Making it a six –point locking
system much like a bank vault.
Concrete Cap:
We use a 6 inch thick and 24 inch wide, length cut to fit
horizontal ICF form called Lite Deck
as the basis of our shelter cap and place it 10 inches down
inside the 8 foot tall safe room walls giving you a 7 feet 2
inch ceiling. We then put rebar in the
Beam Pockets and a grid of rebar across the top on 1
foot centers. Then tie it all together with a five foot
piece of 5/8 inch rebar that has been bent in the center on
one foot centers around the top, going into the wall cavity
and on top of the grid. |
