A tensile swimming pool structure is a type of pool that uses a tensioned membrane or fabric to create the walls and roof of the pool. This type of pool is often used in commercial or public settings, and can be designed in a variety of shapes and sizes. Tensile pools are typically made from PVC or Teflon-coated fabric, and are known for their durability, ease of maintenance, and ability to withstand wind and weather. They can also be designed to be energy-efficient, using natural light and heat to keep the pool warm.
