Wooden sports flooring is used for sports halls and gyms. They are produced from water-resistant plywood and wear layer from noble woody plants - especially from beech or oak. Parts are assembled onto a prepared flexible grate which secures area-wide flexibility of the whole floor. Wooden floors on a flexible grate are very popular especially where basketball is played. Recently, they have been considerably replaced with artificial playing surfaces, less demanding on maintenance and susceptible to repairs caused by moisture. Wooden floors belong among the so called area-widely elastic sports surfaces (unlike artificial, cast floors, which are POINT elastic).
