5-a-side venues typically run for extended hours, with intense use focused around the goal area and central passing lanes. Operators often need a surface that can be installed quickly, remain stable under heavy rotation, and limit maintenance complexity.
Vivaturf has developed 5-a-side-oriented non-infill configurations that target this “small pitch / high intensity” profile—aiming to balance sport interaction, durability, environmental performance, and operational efficiency through controlled engineering parameters and system design.
1. Technical Requirements for 5-a-Side Non-Infill Turf (Aligned with FIFA and GB/T 36057-2018)
5-a-side pitches require performance tuning that differs from full-size football fields. The focus is on impact moderation, reliable traction, controlled ball behavior, and resistance to concentrated wear. Vivaturf’s parameter ranges are designed to align with FIFA-referenced targets and China’s GB/T 36057-2018 test framework.
1.1 Sport Interaction Parameters (High-Frequency Stop-Start Play)
- Shock absorption: target range 50%–65% (FIFA-referenced), supporting impact reduction without excessive softness
- Vivaturf measured range: 52%–62%
- Vertical deformation: recommended 2.0–4.0 mm for compact, high-frequency play
- Vivaturf measured range: 2.1–3.5 mm
- Ball rebound ratio: 0.72–0.88, aimed at keeping rebound behaviour close to natural-grass expectations (deviation referenced ≤6%)
- Ball roll consistency: distance deviation ≤4%, rolling friction coefficient 0.42–0.55
- Sliding resistance:0.35–0.65 (range), balancing grip for sharp stops while reducing abrasion risk
- Vivaturf measured range: 0.40–0.52
These ranges are intended to support quick turns, controlled sprints, and frequent transitions typical of 5-a-side play.
1.2 Durability Parameters (Concentrated Wear + Outdoor Exposure)
Because 5-a-side venues can operate 8–12 hours per day, turf systems must resist both abrasion and aging.
- Lisport XL wear performance:
- FIFA reference: ≤6% fiber breakage after 5,000 cycles
- Vivaturf reference: ≤3% fiber breakage after 8,000 cycles
- Single-yarn mechanical strength:
- Tensile breaking force ≥130 N
- Elongation at break 40%–55%
- Tear resistance ≥28 N/mm
- Backing and seams:
- Bonding strength ≥2.0 MPa (baseline requirement)
- Vivaturf measured bonding strength: ≥2.3 MPa
- Seam strength requirement: ≥1,600 N / 50 mm
- Weather resistance:
- UV aging 1,000 h: color fastness ≥ Grade 7
- Climate tolerance: −30°C to +75°C
- Mold resistance: ASTM G21 rating 0
- Drainage:
- Permeability ≥8 L/(m²·min)
- Vivaturf measured permeability: ≥9 L/(m²·min)
- Rapid surface recovery after heavy rain under typical drainage design conditions
1.3 Environmental and Site Adaptability (People-Dense Locations)
5-a-side pitches are often located near schools and residences, increasing the importance of emissions control and safe material selection.
- Heavy metals (content control): Pb ≤5 mg/kg, Cd ≤0.1 mg/kg, Hg ≤0.1 mg/kg (as provided)
- TVOC emission rate: ≤0.25 mg/(m²·h)
- Formaldehyde: not detected in referenced testing
- Manufacturing VOC control: ≤5 mg/m³
- Environmental alignment: referenced compliance with EU Ecolabel and related environmental assessment expectations
Operational adaptability:
- Modular installation with customizable panel sizes (commonly 3 m × 4 m)
- Installation schedule typically reduced by 25%–30% versus infilled systems
- Post-installation flatness tolerance ≤2 mm / 3 m, supporting compact pitch geometry
