foundations: asphalt foundation, cement foundation, and stone powder stabilization foundation. Which type is mainly determined by the local climate, budget, and time. The asphalt foundation is especially suitable for the climate with large temperature difference in the north and low winter temperature. At the same time, because of its high cost, it is not the most suitable foundation type for warm and humid environment. Cement concrete foundation is more common in the south because of its simple construction, reasonable cost and rapid drainage. Although the stone powder stable layer is low in cost, Because of its poor rigidity and stability, the foundation is prone to looseness after prolonged use, resulting in uneven foundation. Therefore, in most areas of China, the cement-concrete foundation has become an economical, cost-effective artificial grass foundation type. The following is a brief introduction to the

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%, the error of 5m ruler is 3mm, the slope is 8‰ in the horizontal direction, 5‰ in the longitudinal direction and 5‰ in the semicircular area. The surface should be flat, smooth and ensure drainage.

2. The foundation of 

3. The surface is even and solid, no cracks, no rotten side, the expansion joint is straight and smooth, dicing about 6000 *6000mm.

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 of period is more than 20 days.
