Evolution of Swimming Pool Design and Construction  

by Pool Builders on 01-26-2010 in Articles

Swimming pool design has changed dramatically over the millennia. Early designs were square or rectangular constructs that were lined with bricks or blocks and sealed with a bituminous material. The biggest change in contemporary swimming pool design is organic rounded shapes that are built out of a variety of materials. Variations in pool design include infinity edge pool, natural pools, and zero-entry pools. The infinity edge creates the illusion that the water surface continues infinitely by allowing one edge of the pool to have a flow over design. Natural pools are man made pools that incorporate filters and animals and plants in the natural environment to maintain water health. Zero-entry pools attempt to recreate the natural descent into the pool by sloping to the edge instead of using steps. On the other hand, swimming pool construction has seen miraculous changes and use highly advanced technology to maintain water quality. Swimming pools have become complex designer environments that can include waterfalls, hot tubs, gardens, sliding boards and tubes. Another big change is where pools are being built. Technological advancements make it possible to find swimming pools in unusual places such as cruise ships, rooftops, inside private homes, and on the edge of ocean cliffs.

Construction techniques have had several engineering advancements that have lowered inground pool prices [http://hubpages.com/hub/Estimating-Inground-Pool-Prices]. In the 1930's, pneumatically applied concrete was an innovation that allowed pool construction to break the mould of traditional pool shapes. Instead of being restricted by rigid geometric formwork the new application process allowed curved shapes using excavated earth as the form. Instead of using bitumen to seal the pool interior a new silicate material called plaster was introduced around the same time.

Other innovations came about to help maintain water quality. Traditional water cleaning involved hand filtering with cloth or using skimming tools and strainers. A water cleaning process called recirculating overflow became an industry standard. It used filters and pipe to circulate the pool water through a filter and back into the pool. It had a major drawback; it was expensive, was high maintenance and had a short lifespan. A new construction took its place and was a simple perimeter made from low maintenance stainless steel.Today, it is found in many commercial pools. Further advancements in water sanitation occurred early in the twenty first century with the arrival of ultra violet light technology. Water purification is critical because of the risk of spreading disease passed on through animal excrement, mosquitoes and from people.
