人造草坪由3层材料组成。Base Layer是由夯实土层、碎石层和沥青Or混凝土层组成。基础层要求坚实、不变形，表面光洁和不透水，即一般的混凝土场地。由于Large site area,The basic layer must be handled properly to prevent subsidence. If the concrete layer is laid, the expansion joint shall be cut after the concrete is solidified to prevent thermal expansion deformation and cracks.

On top is a buffer layer, usually composed of rubber or foam. Rubber Elasticity is moderate, thickness 3~5mm. The cost of using foam plastic is low, but the elasticity is poor, the thickness is 5~10mm, the too thick lawn is too soft, and it is easy to sag; It is too thin and lacks elasticity, which can not play a buffering role. The buffer layer should be firmly pasted on the base layer, generally used或Paste.

The third layer, too,Layer. According to the surface shape of the manufacture, there are fluff turf, toroidal curly nylon turf, leaf polypropylene fiber turf, and permeable turf made of nylon yarn, etc. This layer must also be glued to rubber or foam with LaTeX. During construction, it must be fully glued, pressed tightly in turn, and cannot be folded.
