There are three types of commonly used artificial grass foundations: asphalt foundation, cement foundation, gravel foundation, which type is mainly determined by local climate, budget and time. The asphalt foundation is especially suitable for the climate with large temperature difference in the north and low temperature in winter. At the same time, because of its high cost, it is not the most suitable basic type for warm and humid environment. The gravel foundation is simple in construction, low in cost and quick in drainage. It is more common in the south, but because of its poor rigidity and stability, After long-term use, the foundation is loose, which leads to uneven foundation; therefore, in most areas of China, the cement-concrete foundation has become an economical, cost-effective artificial grass foundation type. Based on the rich experience of artificial grass system, Shuanghe Sports makes a brief introduction to the artificial grass cement concrete foundation as follows:
1. The basic surface flatness is required to ensure the uniform thickness of the artificial grass surface layer and uniform elasticity. The pass rate of flatness is above 95%.
5m ruler error 3MM, slope: horizontal 8‰, vertical 5‰, semi-circular area 5‰, the surface should be flat, smooth, and ensure drainage.
2. The foundation should have a certain strength and stability.
3. the surface is even and solid, no cracks, no rotten side of the surface, the seam is straight and smooth, dicing about 6000mm × 6000mm as well.
4. The mat is laminated, the compactness is greater than 95%. After the medium-sized roller compactor is pressed, there is no significant wheel track, no loose soil, waves and so on.
5. The cement foundation 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.
6. Need to consider leaving expansion joints, the width is 5 mm.
7. The basic maintenance period is 2-3 weeks.
