Good technical parameters do not automatically become good field performance. They must be delivered through correct installation and acceptance testing.
Base Flatness
Non-infill turf does not have a thick infill layer to mask base imperfections. Therefore, base flatness is critical.
Recommended control references include:
- Asphalt or concrete base flatness: 3 m straightedge deviation controlled within approximately ≤3–5 mm
- For high-performance fields, tighter control around ≤3 mm is preferred
- Proper drainage slope, typically around 0.3‰–0.8‰, depending on field design
Vivaturf applies quantified base inspection and laser-assisted acceptance methods in suitable projects to improve field consistency.
Seaming and Fixing
A non-infill system must have strong seams and stable edge fixing. The use of proper seam tape, adhesive systems, and edge reinforcement is essential.
If seam strength is weak, curling or lifting may occur under thermal expansion, contraction, or high-frequency play. Once a seam lifts, localized tearing and field damage can develop quickly.
Clear Acceptance Standards
A professional project should reference applicable standards and testing methods, such as:
- GB/T 20394 for artificial turf performance references
- GB 36246-2018 for synthetic sports surfaces in school applications and harmful substance limits
- FIFA Quality or FIFA Basic testing methodology for football-related fields where applicable
- Impact absorption, vertical deformation, ball rebound, ball roll, friction, drainage, aging, and environmental testing
For international projects, specifications should be adapted to local regulations and recognized testing methods used in Europe and North America.
