The economic advantages of non-infill turf extend across procurement, installation, maintenance, and replacement. When evaluated alongside technical performance and environmental impact, these advantages become even more pronounced.
In procurement, non-infill turf offers a controllable total cost per unit area. While its unit price may be slightly higher than some low-end infill systems, it requires no additional quartz sand or rubber granules. Industry benchmarks show that traditional infill turf typically costs approximately RMB 80–120 per square meter, with an additional RMB 47–76 per square meter for infill materials, bringing total procurement costs to roughly RMB 127–196 per square meter. Natural grass systems generally range from RMB 170–230 per square meter when soil improvement is included. Stadium-grade non-infill turf, by contrast, typically costs RMB 100–150 per square meter with no infill requirements, resulting in a total procurement cost advantage of 14–49% compared with infill turf and 12–56% compared with natural grass.
From a performance perspective, non-infill turf designed for stadium use typically features fibers of at least 6,000 Dtex, tensile strength above 30 N per fiber, elongation at break above 35%, and initial rebound rates exceeding 90%. These parameters support high-frequency athletic activity and reduce premature replacement risk. Transportation costs are also lower, as non-infill systems do not require separate logistics for infill materials.
Installation efficiency further strengthens the economic case. Traditional infill turf installation involves multiple steps, including infill spreading and compaction, resulting in installation periods of approximately eight to twelve days per 10,000 square meters. Natural grass installations may take fifteen to twenty days. Non-infill turf systems, using modular installation methods, typically require only three to five days per 10,000 square meters, with significantly reduced labor input. Structural stability parameters, including backing tensile strength of at least 18 MPa and peel strength above 2.8 N/mm, contribute to low rework rates of under 1%, further minimizing installation-related costs.
Maintenance represents the most significant long-term cost factor for sports venues. Natural grass requires frequent irrigation, mowing, fertilization, pest control, and replanting, resulting in annual maintenance costs ranging from RMB 230–470 per square meter. Traditional infill turf requires periodic infill replenishment, grooming, and surface treatment, with annual costs of approximately RMB 52–94 per square meter. Non-infill turf requires only routine surface cleaning and periodic inspections, with annual maintenance costs typically limited to RMB 5–8 per square meter.
Non-infill systems also demonstrate excellent environmental resilience, remaining usable in temperature ranges from –10°C to 60°C with no dormancy period. Enhanced UV resistance ensures color fastness of at least grade 7 after extended exposure testing, with performance degradation below 5%, reducing the need for localized replacement. The absence of chemical treatments and infill materials eliminates additional environmental remediation costs commonly associated with other turf types.
Replacement economics further highlight the advantages of non-infill turf. Natural grass typically requires replacement after five to seven years, while traditional infill turf lasts six to eight years. Non-infill turf systems can achieve service lives of eight to ten years or longer. Replacement processes are simpler and faster, typically requiring only three to five days per 10,000 square meters, significantly reducing venue downtime and associated revenue loss. High wear resistance ensures rebound rates above 85% after 10,000 high-frequency impact cycles, supporting daily usage of ten to twelve hours and minimizing premature replacement.
