The yarn must not only stand upright; it must also be securely anchored.
Vivaturf’s reinforced backing system is designed to support fiber retention and dimensional stability through a multi-layer structure, which may include:
- High-density glass-fiber grid reinforcement
- High-strength structural reinforcement layers
- Heat-bonded or advanced locking technology
- Backing systems designed to reduce hydrolysis and delamination risk
A strong backing system can help the turf achieve a yarn pull-out force of around 35 N or higher, which is significantly stronger than many ordinary turf products around 20 N.
For humid or outdoor environments, hydrolysis resistance is also critical. A high-quality backing system may retain approximately 95% of its strength after 1,000 hours of accelerated hydrolysis testing, helping reduce the risk of backing separation in high-humidity conditions.
Layer 3: Shockpad Layer — Closed-Cell Cushioning and Macro Support
The shockpad is often overlooked, but it is essential for overall field performance.
A mature non-infill turf system should use a customized closed-cell PE shockpad or equivalent elastic layer. The closed-cell structure helps provide:
- Shock absorption
- Load distribution
- Anti-collapse performance
- Moisture resistance
- Long-term cushioning stability
For many sports and training applications, the system may be designed to achieve:
- Vertical deformation: approximately 5–8 mm
- Shock absorption: approximately 40%–55%
- Controlled recovery under repeated compression
This combination helps balance safety and support. A field that is too hard increases impact stress; a field that is too soft can reduce stability and affect movement efficiency.
Low-quality systems may omit the shockpad or use recycled foam with inconsistent cell structure. Such pads may compress permanently, leading to a hard or unstable field surface after relatively short use.
