1, the basic surface roughness requirements are high to ensure that the artificial grass layer thickness consistent, elastic uniform. Smoothness pass rate of 95% or more, 5 meters ruler error 3MM, slope: Horizontal 8, longitudinal 5, semicircle area 5, surface should be flat, smooth, ensure drainage.
2, the Foundation should have certain strength and stability.
3, the surface is even solid, no cracks, no rotten edge pock, seam straight and smooth, to 6000mmx6000mm around to cut into good.
4, cushion compaction, compactness is greater than 95%, after the medium roller press, no significant wheel traces, no topsoil loose, waves and so on.
5, the Cement Foundation must have the water compartment, the separation layer uses the new PVC thickened diaphragm film, the junction should be greater than 300mm, the edge margin is greater than 150mm.
6, the need to consider the expansion joint, width of 5 mm. 7. The basic maintenance period is 2-3 weeks.
