History of Pool Construction

Paddock developed the very first high flow vacuum sand filter. More recently, they introduced the first ultraviolet water sanitizing system for pools.

Paddock was the first company to use gunite, a term used to describe pneumatically applied concrete. Before gunite, pool builders would use traditional poured in concrete, which was not as durable and did not allow the construction free form pools. Guinite is made up of cement mixed with sand. It is applied through a hose under pressure to the side of a pool.

Paddock also developed the first permanent pool finish besides tile. They named it silicate. Silicate was later replaced with a more versatile pool interior surface called Marcite, known today simply as plaster.

Paddock introduced the first pool recirculating overflow system to clean debris from surface water. Before this invention, pool operators would have to clean surface water through manual skimming using a net or simply let the surface water flow to waste.

Although the recurculating overflow system was a huge development for cleaning surface water, the technique required the installation of piping around the pool's perimeter. This piping would break down over time and have to be replaced. To solve this problem, Paddock developed a water skimming system that did not require the use of perimeter piping. A gutter system was created using channels made of stainless steel that surround the pool, eliminating the need for piping.

The pipeless perimeter system requires a large storage tank to hold enough water to keep the water level of the pool constant. Storage tanks are expensive to build, and this was a major drawback to the system. Paddock helped solve this problem by enabling the pool to serve as a surge capacity, instead of a surge tank.

Paddock has been a leader in commercial swimming pool construction and has developed many innovations that have improved the quality of swimming pools.
