Solutions for Swimming Pools

Outdoor Swimming Pools
Two basic alternatives are available for outdoor swimming pools: in-ground pools and above-ground pools. In-ground pools are set into the ground, thus requiring ground excavation. Only solutions for in-ground pools are presented here.
Main Components of in-ground Swimming Pools
The main components are:
Structure: floor / foundation; walls
Waterproofing element
Decorative finishing
Equipment and accessories
The structure itself is usually not sufficiently watertight, and therefore a waterproofing element is needed. In case of a conventionally built structure, this waterproofing element consists of a cementitious coating. It serves at the same time as a substrate for the decorative finish which is made up of ceramic tiles (or mosaic) or a decorative coating. Sheet membranes offer an alternative solution, combining the waterproofing and finishing function in a single element.
“Membranes”, consisting of thicker and more robust sheets, are installed in the traditional way, by cutting and seam welding on site. By contrast, “liners”, consisting of thinner sheets, are completely prefabricated to the size of each pool and then installed simply by attaching them onto profiles on the pool edge. They can also be easily replaced at the end of their service life.
Design Swimming Pools
Swimming pools must be designed by specialists in accordance with the state of the art, as well as standards and regulations in force.
Requirements for Swimming Pools
Esthetic Requirements
Free pool geometry
Wide choice of esthetic design possibilities (colours and patterns of pool surface)
Colour stability
Economical Requirements
Favorable investment cost
Ease of cleaning
Easy and cost-effective renewal possibilities
Durability Requirements
Mechanical (impact) resistance
Resistance to substrate cracking and movement
Frost resistance
Resistance to (chlorine; ozone) treated water
Resistance to sun cream
Resistance to algae and mold growth
