A high-quality non-infill system does not simply remove sand and rubber granules. It must redesign the turf structure so that the yarn, backing, and shockpad work together.
Vivaturf non-infill turf is engineered around three main structural dimensions.
Yarn Morphology and Self-Supporting Fiber Design
Vivaturf uses a straight-and-curled yarn structure, 3D-shaped yarn profiles, and engineered support fibers. The straight fibers provide upright structural support, while the curled fibers add resilience, cushioning, and lateral stability.
This type of yarn structure helps the surface maintain recovery and friction control without relying on infill particles.
In premium non-infill systems, engineered yarn structures may include micro-groove or shaped-profile designs that improve resilience, surface grip, and fiber recovery.
Higher Functional Tufting Density
Because non-infill turf cannot rely on loose particles to support the fibers, the turf carpet must create more contact points through its own structure.
Premium non-infill turf systems may use tufting densities in the range of approximately 16,800–21,600 tufts/m², which can be around 60%–100% higher than many conventional filled systems.
This higher functional density helps distribute load more evenly, reduces stress on individual fibers, and improves long-term wear resistance.
Reinforced Backing and Structural Locking
Without infill weight, the backing system becomes even more important. Vivaturf uses a reinforced composite backing structure, often supported by glass-fiber grid reinforcement and advanced locking or coating technology.
Typical high-performance references may include:
- Peel strength: ≥ 2.8 N/mm
- Backing tensile strength: approximately 18 MPa or higher, depending on product structure
- Drainage rate: often above 60–85 L/(m²·min) in well-designed systems
These parameters help address common concerns such as curling, delamination, fiber loss, and long-term deformation.
