There are three types of commonly used green Artificial Turf Carpet basics: asphalt surface, cement surface, broken stone surface. Which type is mainly determined by local climate, budget and time. The asphalt surface is especially suitable for the northern temperature difference and winter. The low temperature climate, but also because of its high cost, is not the most suitable basic type for warm and humid environment. Because of its simple construction, low cost and rapid drainage, the broken stone surface is more common in the south, but because The rigidity and stability are poor, and the foundation of the material surface is prone to looseness after long-term use, resulting in uneven surface;
Therefore, in most areas of China, the foundation of cement concrete surface has become an economical and practical, cost-effective artificial grass surface type.
First, the surface finish of the material surface is required to be high, so as to ensure that the grass surface of the artificial grass is highly uniform and uniform in elasticity. The pass rate of flatness is above 99%, the error of 5m ruler is 5MM, the slope is 5‰ in the horizontal direction, 5‰ in the longitudinal direction and 3‰ in the semicircular area. The surface must be flat, smooth and ensure drainage.
Second, the basic material surface should have good strength and stability.
Third, the material surface is even and solid, no cracks, no rotten surface, the seam is straight and smooth, and the cut is best with 60m×60m.
Fourth, the mat is laminated, the compactness is greater than 96%, and there is no significant wheel trace after the medium-sized roller compactor is pressed, no loose soil and waves.
Fifth,The cement base material surface must have a water-repellent layer. The water-repellent layer is made of a new PVC thick water-repellent film. The junction should be greater than 300mm and the margin margin should be greater than 150mm.
Sixth, need to consider leaving expansion joints, the width is 5 mm.
