There are many advantages of artificial grass, for example: the green of its four seasons, the appearance of bright, lively, good drainage performance, long life and low maintenance costs.
artificial grass sports system based on quality requirements are mainly concentrated in three areas: hardness, flatness and drainage slope.
The artificial lawn foundation three categories: asphalt base, cement foundation, gravel base, which type is mainly determined by the local climate and environment and the budget, time, asphalt base, especially for the northern large temperature difference between climate and environment and low winter temperatures, also because it is expensive for a warm, humid environment is not the most suitable foundation type, gravel foundation because of its simple construction, low cost, rapid drainage, more common in the South, but because of its rigidity and stability prone to the foundation loose after prolonged use, leading to uneven foundation; Therefore, in most regions of the domestic cement concrete foundation became economic cost is very high base type of artificial grass.
Double and sports a wealth of experience in the artificial grass system, synthetic grass cement concrete foundation do brief as follows:
1, higher requirements on the basis of surface flatness, to ensure that the artificial turf surface layer of uniform thickness, uniform elasticity. Flatness pass rate above 95%, and 5 m ruler error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, the semicircle area 5 ‰, the surface should be flat, smooth, to ensure drainage.
2, the base should have a certain amount of strength and stability.
3, uniform surface and solid, no cracks, no bad side pockmarked face, straight and smooth seams, 6000mm × 6000mm cuts as well.
4, cushion compaction, density greater than 95%, after the pressure of the medium-sized rolling machine, no significant round track, no surface dust loose, wave phenomena such.
Cement foundation necessary aquifuge the new PVC thickened aquifuge impermeable film, the junction should be greater than 300mm edge margin greater than 150mm.
6 need to consider the extension gap width of 5 mm.
7, soccer grass the basis of the maintenance period of 2-3 weeks.
