builds Gunite pools. Gunite is pneumatically applied concrete, which can
achieve strengths of 6000 to 7000 PSI (cast in place concrete is usually
3000 to 3500 PSI). Gunite's strength is the result of the dense packing of
the material as it is sprayed, as well as the fact that a relatively small
amount of water is required to hydrate the cement.
Gunite has been used in the
construction of swimming pools for well over 30 years. This includes
Olympic competition pools and the swimming pool at the White House in
Washington, DC. Gunite is uniquely desirable for pool construction because
of its inherent strength as well as it's adaptability to unusual shapes.
Gunite is particularly useful on vertical surfaces such as pool walls
where extra strength is important.

Forms
are installed which outline the perimeter of the pool. Gunite
pools can be built in any shape or size.
The crush stone
sub-base is prepared, and the pool piping is installed and pressure
tested.

A steel
reinforcing grid is installed to give your pool superior strength. Also, walls where water depths are greater than 5' receive
additional vertical reinforcement.
The floor of the pool is placed using
ready mixed concrete. The walls, as well as any steps or bench seats, are
then constructed using Gunite.
This combination of Gunite/Concrete and
steel reinforcement produces an extremely strong and durable pool shell.

The interior of the pool receives a
row of 6" x 6" ceramic tile at the waterline, while the
remainder of the pool walls and floor are finished with a 1/4" to
1/2" thick layer of Marblelite.
Marblelite consists of two parts
crushed Georgia Marble mixed with one part of white portland cement. It is
hand troweled to a smooth, yet slip resistant surface.
A properly cared
for Marblelite finish does not require painting and can last for many
years.
