I am tinkering with an idea in my new house design - that the living area
be sunk about 1200mm, and one wall is clear polycarbonate, forming one
wall (the top part anyway) of the pool outside. So it's a kind of aquarium
effect, looking into the pool from the house. Any thoughts on the practicality
of this, and what thickness of poly I'd need? Does the width of the pool
increase the pressure? How about the length, which exttends beyond the poly
wall? I'm guessing so - but what's the limit? I mean, for the sake of the
engineering exercise, how thick a wall is need to hold back an ocean for
a depth of 1200mm and a length of say 5m?
There are several immersive aquariums around the jewnited states so it
should be easy to use the web to find them, contact their management, and
ask to be directed to the architects who designed their "walk-through
aquarium" and poof! you get all the answers you need not very much different
than using the web to find people and facts that prove...

OK, so 1.2 meters tall. How wide? (strength of the plastic would be a
factor affected by width...)
Practical? Depends on how much money you have... There are all kinds
of issues, including insurance (what if it does break?) and the likes.
Commercial jobs I've see have been as much as many inches of
polycarbonate. I've a piece of 3/4 inch polycarbonate sitting in my
shop, I'd perhaps trust it for about half the depth you suggest. I'd
guess (GUESS!!!!) maybe an inch and a half would be safe.
No, but it increases based on the width of the plastic panel. The PSI
load won't change based on the size of the body of water, only the
Same as to hold back any other body of water of a given depth...
Water, per foot of depth exerts about .443 PSI. So if your plastic
wall is about 5 ft tall, the pressure at the bottom (assuming the
water's top level is even with the top of the plastic), would be about
2.2 PSI. A plastic wall, 5 ft tall, and 10 ft wide, has a surface area
of 7,200 sq inches. Time the PSI at the bottom (worse case engineering
used here) brings the total pressure on the wall to 15,840 lb. You are
talking mounting the plastic in a well reinforced concrete wall,
right? The mounting will have to be carefully engineered so the water
pressure pushes the plastic into the wall, not out (the plastic woudl
be on the water side of the wall).
It is a cute idea... An interesting tropical home (never practical in
a non-tropical environment, IMHO.) Consider also that you'd be best
off if you laminate glass to the plastic to protect it. Polycarbonate
is very soft and will scratch easily. Without somethign to protect it,
it will look like do-do in a few years.
