Tens of thousands of them. Maybe hundreds of thousands of them.
In some locations there is so much ledge it is just not possible to make a
hole in the ground. It would be blasting out solid rock. Other parts of
the country have high water tables and it would be like building a house
over a swimming pool. Those modestly cost houses made the American dream
come true for many families.
Here in my area in Maine the Ledge is BAD...I have a full basement but it is
built into the side of a hill and they poured the foundation and filled in
around it on 3 sides...The front wall in the basement is wood with a door
and windows...LOTS of fill..You can't dig 3 feet most places around here
without explosives...LOL..Lots of slab , and partial or crawl space
basements here.....Not a damn thing wrong with it either....Not everyone can
afford a macmansion....Me included...Ranch with a full basement here...
In Arizona weather is very mild. Been there many times. I know you can
have a full basement there if you want to. Cost is the matter. Where I
live, not having a full basement is almost unthinkable. There are old
houses built during the war which most of them now have dug out
basement(like retrofitting one). Our frost line is over 6 feet deep.
Right now a friend of mine is building a house and he ran into a big
boulder while excavating for basement. To clear the obstacle, it cost
him 20K but basement is poured according to plan.
I'm in Houston. Houston is built on 500' feet of clay... before you get to
sandstone. The tall buildings downtown are constructed on "floating"
foundations and not anchored in bedrock.
The tall buildings here have basements - that's what holds them up! But
nothing shorter than about five stories has below-ground construction -
certainly not residences, three-story condos, apartment buildings.
Up here in Calgary is pretty similar. Clay or sandstones. No wonder we
have kazillion lakes small and big and ponds every where. One reason
they can't build subways. Downtown high rise commercial buildings are
like yours with mandatory bilge pumps deep in multi level
basement(parkade). I am a life time ham and due to the soil condition
hams here have problem with poor electrical ground which affects our
antenna arrays performance.
It would be great to have a basement here in AZ just to escape the summer
heat. Several days in July my thermometer read 117.
I grew up in Michigan and started sleeping in the basement because my dad
was to cheap to run the heat much. I loved the somewhat constant temps down
There are always remodeling work arounds if you don't have a basement to run
They built/build subways in Amsterdam. Below ground water level. Most
homes in Holland have basements. Below ground water level. I think they
just know how to make them waterproof. The weight of the house probaby
keeps it from floating away.
The problems with building the subway in Amsterdam have to do with the
pumping away too much ground water. damages the foundation structure. The
wooden poles in the water and ground start rotting when they get exposed to
air, and the buildings start cracking.
