How important is the strength
of your home? Watching the evening news, it is
hard to forget the damage hurricanes and tornadoes
have done to peoples’ homes. All areas of
our country are subject to storms that can cause
tremendous damage. Everyone deserves a home that
is strong and protects their families. The question
is how strong is a conventionally built house?
Let us examine the construction process.
The first step in the construction process is
the foundation. This is generally a concrete strip
1 to 2 feet wide and 6 to 12 inches thick around
the base perimeter that supports the house. This
foundation is the interface between the home and
the ground and must be below the freezing line.
This prevents the foundation from cracking in
the winter when the ground swells due to freezing.
The next step is to construct a block or concrete
wall upon the foundation. This wall will extend
to the ground level or higher. For homes with
basements these walls must be strong enough to
hold back the dirt that is pushing against it
especially when the ground is wet. Following the
below grade construction you would attach your
above grade walls. These walls are constructed
using wooden boards of either 2" x 4"
or 2" x 6" studs 8' in length. The wood
framing is assembled using nails that are 3 ½"
long, two of which are used to attach the studs
to the top and bottom plates every 16 or 24 inches.
More studs are used around windows, doors and
corners for strength. (This is the reason there
is poor insulation around windows and doors frames
because wood has a low R-value.) External sheathing
is attached to these walls for rigidity and a
barrier to the outside, this is generally a fiber
board or a low grade of 1/2" plywood. It
is not difficult to punch a hole through these
materials. The walls are with wrapped a plastic
material for vapor barrier to prevent moisture
from entering the house. The final external touch
is either siding, stucco or for the more expensive
house a brick veneer. Internally, insulation is
placed between the wood studs and ½"
gypsum board is nail or screwed to this framing.
These homes are not very strong. This is the reason
you see such devastation from severe storms. Now
to our "Super Home" and its construction
and the reason we can say a hurricane or tornado
can’t destroy our homes.
Our walls comprises an interlocking polystyrene
block system into which high strength steel and
concrete are placed. These walls are very strong.
Our foundation is a little larger to support the
weight of steel and concrete. Steel is use in
the foundation and extends into our wall system
to form a strong interlocking bond anchoring the
home in the ground. This will give the home a
strong anchor against extreme storms. Steel of
high strength is place inside our polystyrene
blocks to form a matrix of 16" squares.
Each piece of steel can withstand a tensile pressure
of 92,000 lbs. before it is pulled apart. This
prevents cracking and adds tremendous strength
both compressively (downward) and laterally (pressure
that pushes against our wall). Once the blocks
and steel are in position high strength concrete
(3,500 psi) is pumped into the forms. This creates
a monolithic steel reinforce wall system. To give
an idea how strong these walls are let’s
compare them to a 2" x 6" wooden framed
section 8 feet long which has a similar surface
area of 600 square inches on top to an 8' section
of our wall. If you multiply 3,500 psi (pounds
per square inch) by 600 sq in., our walls could
withstand more than two million pounds of downward
force as compared to 10 to 15 thousand pounds
for the same surface area of wood walls. It is
not unusual for the concrete in our wall to cure
above 5,000 psi, at this strength it could support
over three million pounds of pressure. Sever storms
have a tendency to tear a house apart because
of the intense pressure that is created against
the walls. Our walls have been test to withstand
winds over 200 miles per hour. In one test a 2"x
4" 8' wooden board was shot at our walls
with a velocity that would be generated in a storm
with 250 mph winds and there was no damage to
the wall. This is truly a "Super Home".
