Tartan track
A plastic sheet (often called tartan track ) is used in athletics, especially for running and jumping competitions. Secondary areas, mostly from the same material as the actual carrier, serving the throwing events. Also small playing fields for basketball, volleyball and other ball sports are often made of this material installed in the semi- circular segments behind the soccer goals.
In German-speaking three different plastic floor systems are offered traditional, but increasingly rare built threshing floor coverings essentially. They are installed on asphalt, in exceptional cases, to concrete or old sports floors. There are produced in the local installation synthetic tracks, so-called in-situ soils, hybrid surfaces made of prefabricated elements and in situ components and synthetic tracks from completely prefabricated individual elements.

Situ soils
The most frequently installed in Germany variant of a plastic sports floor in outdoor sports facilities is the so-called in-situ lining. Situ soils are made only on site at the site. They usually consist of styrene-butadiene rubber (SBR) of recycled, granules of the synthetic rubber, ethylene -propylene-diene rubber ( EPDM), and the binder polyurethane (PUR). These components are mixed on site, in applied condition pulped, leveled and compacted. The composite material is cured and forms an elastic, fixed to the base layer. Situ deposits are usually produced of several such layers, usually made of a elastic rubber granulate ( SBR) and liquid PUR and a wear layer of liquid PUR and EPDM. Leading manufacturers of these soils are in Germany, the company BSW and Polytan.
Hybrid coatings
Hybrid floors are installed the second most in the German-speaking countries. They consist of a pre-produced elastic layer of SBR granules and polyurethane and manufactured and installed on site in -situ method pile made of EPDM. The prefabricated Elastikbahnen be glued in front of the place on the base course of asphalt. The adhesive having the additional function to absorb the occurring mechanical stresses between the asphalt and the elastic layer and to compensate.
The installation of EPDM wear layer in -situ process combines the shock - to-end installed Elastikbahnen together and closes the pores. For a seamless top layer is generated. The thickness of the liquid applied polyurethane EPDM wear layer can be controlled very well, since it is only a few millimeters and the PU is running smoothly and even applied wet-on -wet method. A typical example of a hybrid coating is the synthetic track Regupol by the manufacturer BSW.
Synthetic tracks from prefabricated components
The least likely built sports floors in the German-speaking area are those which consist entirely of prefabricated individual pieces and laid on the construction site to a fixed total area. Your material is usually vulcanized rubber in two or more layers - is the floor system - the elastic layer and wear layer. Such floors are offered in Germany mainly by the manufacturer Mondo.
Surfaces
In-situ soils and hybrid soils may have different surfaces. A distinction is made between structural or spray coated, bulk coated and cast-coated land. Coverings made of prefabricated components have textured rubber mixture layers. In competitive sport, the cast-coated surfaces have prevailed in Germany. Their look and structure are similar to the grain size of EPDM granules those of traditional threshing floor coverings.

History
The first tartan track in Europe in 1968 was installed in the Letzigrund stadium in Zurich.
