Commonly used artificial grass foundation has three categories: basic asphalt, cement base, gravel base, using the type which is mainly determined by the local climate and budget time use, especially for large temperature difference between the north and low winter temperatures in the climate, but also because of its high cost, for the warm and humid environment is not the most appropriate basis for the type of gravel base because of its simple construction, low cost, rapid drainage, more common in the South, but because of its rigidity and stability is poor, long prone to loosen after use basis, leading to uneven foundation; therefore, in most regions of the country, cement concrete foundation became economical and practical, very high cost of basic types of artificial grass.
1, on the basis of surface roughness higher, in order to ensure the consistency of the artificial turf surface layer thickness, elasticity uniform. Flatness pass rate above 95%, 5 m straightedge error 3MM, slope: horizontal 8 ‰, vertical 5 ‰, semicircular area 5 ‰, the surface should be flat, smooth, ensure drainage.
2, the base should have a certain strength and stability.
3, the surface uniformly solid, no cracks, no bad side pockmarked face, straight and smooth seams to around 6000mm × 6000mm cuts as well.
4, cushion compaction, density greater than 95%, after the medium-sized rolling machine pressure, no significant wheel tracks, no topsoil loose waves and other phenomena.
5, cement foundation must have impermeable layer, new PVC thick impermeable layer impermeable film, the junction should be greater than 300mm, edge margin greater than 150mm.
6, consider leaving expansion joints, width of 5 mm.
7, base maintenance period of 2-3 weeks.
Artificial turf product performance characteristics:
A vertical drain fast.
2, easy maintenance.
3, for a variety of unique climate of friction.
4, UV mildew, corrosion, and environmental pollution.
5, almost no damage to the skin.
6, vivid color, suitable for a variety of ground of the best material.
7, sports rebound similar to natural grass.
