|Q 2269: I would like
to know your opinion on using Caliza Capri Limestone honed slabs inside
a swimming pool. The designs call
for the entire inner wall and floor to be clad with this material.
My concern is whether there will be a noticeable deterioration in
the stone over the years from the effect of the Chlorine on the stone.
We can accept slight etching or loss of shine but we would be very
concerned if the stone would deteriorate considerably to the point
of pitting or cracking. David, Philippines. July 20,
Dear David: I don't know much about that particular limestone,
but it being a calcite-based stone I would have your very concerns
myself. Try honed granite. Maurizio, USA
A 1577: I wish
to cover an area around a swimming-pool's deck with loose
stones. These stones must be barefoot friendly (wet bare
feet at that). What type and size of loose stone would work
for this project. Thanks. Noah, March 21.
Noah, Whoa! Loose stones? Could you please elaborate on why
you want something loose around a wet and potential slippery
|A 1296: I need
to know what is the most practical / used natural stone for pool deck.
I need to buy about 50 tons of stone for a project. Stone must be
cool, flat and 1 to 2 inches thick. Jan 2.
Where are you located? Have used several Texas limestones for this
purpose with very good results. JVC, USA,
Many types of flagging would be good here. I think you should start
with slates and bluestones first. Then try some sandstones. Steven,
Pool Decks have been covered by a variety of stones . Currently the
most practical solutions are: Flamed Granite : The rough texture make
the area slip resistant and provides the excellent surface. As Granite
is available in a number of colours, you have a large range to choose
from. The desired thickness slabs can be easily made available. Sandstone:
Sandstone with its natural slip resistant texture is the most IN thing
today. Pool decks can be covered with a wide variety of Natural sandstones.
It is necessary to seal the sandstones applied on pool deck to protect
water marks and water penetration in the stone as sandstone by nature
is porous. If you require any further help please feel free to e-mail
us. Arun, India,
|A 1262: Are there any types of stone,
marble or granite that can be used for lining swimming pools?
Sarah Dec 15,
|R2: Most stone types are suitable for lining
a pool if they are set in concrete and properly grouted. If you used
a polished finish, marble may lose its shine due to surface attack
but this should not affect its structural integrity. The main
area of concern is where stone may be subject to wet/dry cycling,
in this area the stone must be very dimensionally stable, that is,
it will not grow when we and shrink on drying - granites and most
marbles are fine. The use of sandstone as coping requires careful
selection. Jim, Australia,
|R1: Dear Sarah: Yes, there are, but are very
difficult to pin point. Dolomitic marbles from Italy, Greece and India,
and some Ophicalcite represent in general a good choice on the marble
side (for as long as you don't want them polished). Most dark "granites"
do, too. If you like a light color granite, then the only choices
are the Sardinia ones (White or Gray) , the Porrino (pink and gray),
and some US granites from South Dakota, NY State, Rhode Island, and
maybe a few others. Stay away from very absorbent "granites" (see
my "lemon juice test"). And remember, by the pool surrounding, whatever
marble or "granite" you choose, make sure that it has a flamed or
bush hammered finish. Any other finish would be very slippery when
wet! Maurizio, USA,
