Artificial turf by three layers of materials. Base layer is made of compacted soil, gravel and asphalt or concrete layer. Requires a solid base layer, deformation, surface smooth and impermeable, namely general concrete venue. Due to the large area hockey venue, must handle the construction of the base layer to prevent subsidence. If laying concrete layer, after curing of concrete expansion joints to be cut out, to prevent thermal expansion deformation and fracture. Above the base layer is a buffer layer of high quality runway material, typically rubber or foam composition. Rubber elastic medium, thickness 3 ~ 5mm. Direct runway with foam material costs are lower, but the flexibility is poor, 5 ~ 10mm thickness runway material, thick lawn is too soft, and easy to depression; lack of elasticity is too thin, would not achieve the buffer. The buffer layer must be firmly attached to the base layer, usually with white latex or all-purpose adhesive paste. The emergence of artificial turf stadium can be traced back to the sixties. They are the invention of a military project in the United States, to improve the urban teenager's body.

With football, tennis, golf and other sports professional, industrial, commercial development makes the development of sport artificial turf industry has made some progress in recent years. Laminate flooring aka wooden floor (or laminate flooring), until now, its history is not very long, it first appeared in the twentieth century Nordic Sweden. 1977 Austria particleboard production "El" Swedish production company and fire board, "Perley" company formed to develop, and then in Europe and the rapid development of the national track material sales, but then did not get on the surface wear and swelling, etc. solved. In the late 1980s, the United States, "Mitel" company broke through the technical difficulties, the flooring surface add aluminum oxide, and to become a milestone in the development of laminate flooring. In China, laminate flooring was first introduced by Shanghai Huili Group review, the beginning of 1995, foreign direct laminate flooring manufacturers began to enter the Chinese market, due to the wood floor with a comfortable, flexible, and low coefficient of friction, and because non-slip, lasting and durable advantages, wood floors have gradually accepted by people.
