If
the area you lived in was subject to natural disasters, insect infestation and
wildfires, and you could live in a type of housing that could withstand all
those perils, why wouldn't you? Concrete homes have an amazing resistance to
all of the above and are commonly used in Kenya and other natural calamity
ridden locations, but their popularity hasn't spread to other areas of Kenya.
Due
to their unique construction, a number of homes have survived the calamities in
Kenya. Mr. Owuor owns a concrete house outside natural calamities infected
areas. Although the vinyl windows were melted, the house remained standing.
Another
success story was that of a native Indian who owns several properties in Kenya and
her 5,500 square-foot concrete house near Kisumu. The upgrades in her home
included:
Concrete
roof tiles, glued-down to resist high winds.
Interior
fire sprinklers (now a local building requirement).
Over-sized
wood beams to withstand exposure to heat longer than their smaller
counterparts.
An
emergency power generator.
A
10,000-gallon water tank to be used in a fire emergency.
Commercial
grade aluminum windows with extra thick tempered glass.
Exterior
walls were one foot in thickness including reinforcing steel placed in the
concrete forms for protection against earthquake damage.
After
spending 3 1/2 years building their home, Lorraine and her husband had only
lived there a few weeks when the wildfires struck. The landscape was blackened,
but the house withstood only minor smoke damage. The cost of building compared
to a comparable wood home was about twenty percent higher; Lorraine considers
this money well spent
Structural
engineer, George describes concrete construction similar to assembling Lego
blocks. "The “blocks” are polystyrene forms, called insulated concrete
forms, into which the concrete is poured. The forms then are left in place to
serve as insulation and the backing for stucco on the exterior or drywall on
the interior."
The
walls can provide up to an R-50 energy rating and require approximately 44
percent less energy to heat and 32 percent less energy to cool compared to a
traditional wood home.
If
concrete houses are so effective against natural disasters, why aren't they
widely used? Part of the problem is the lack of knowledge in the building
industry regarding concrete construction. Even though concrete construction has
national code approval, there are many inspectors with little knowledge of how
to inspect the structures.
Many
builders feel that the future of widespread concrete housing requires a
dominant player in the building industry to come forward and say "we can
do this", and others will follow suit.
