As a complete artificial turf field, there must be a foundation, in order to play a positive role in the turf layer, the quality of the foundation should at least meet the requirements of hardness, flatness and drainage slope, so that artificial turf can present a more perfect state.
There are three main types of artificial turf roots, namely asphalt foundation, cement foundation and gravel foundation. Which one is actually selected depends on the local climate and the relevant project budget.
For these kinds of artificial turf foundations, although the foundation of the gravel is simple in construction, low in cost and quick in drainage, due to its poor rigidity and stability, it will appear loose after long-term use, resulting in uneven artificial turf. Therefore, the cost performance of cement foundation is relatively high.
When the artificial turf cement foundation is applied, the demand of surface flatness is higher, because it directly affects the thickness and elastic uniformity of the artificial grass surface layer, so the flatness of the cement foundation should be controlled above 95%.
Since it is the foundation of artificial turf, it must have a certain strength and stability, and it is not allowed to have defects such as cracks and rotten edges. It is better to arrange dicing at 6000mm×6000mm. In addition, the cement foundation must be provided with a water-repellent layer, which can be made of PVC thick water-repellent film.
During the construction process, a certain expansion joint should be left for the artificial turf cement foundation to avoid adverse effects caused by thermal expansion and contraction. Generally, the root period of artificial turf is 2-3 weeks. After this period of time, other parts of the construction can begin.
