Building a Gunite Pool
| National Pools of Roanoke, Inc.
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. |

The filter system is designed to efficiently clean and purify your pool water. |
