Traditional infill turf relies on sand and rubber granules to help support the fibers and provide cushioning. Non-infill turf removes those loose infill materials, which means the turf must rely on its own structure to provide support, cushioning, recovery, and durability.
This is where high-quality products and low-grade products differ most.
2.1 Bionic Straight-and-Curled Yarn Structure
High-quality non-infill turf normally does not use a single type of straight yarn. Instead, it often uses a straight-and-curled yarn system.
Vivaturf uses a bionic straight-and-curled yarn matrix, commonly designed around a balanced combination of straight support fibers and curled elastic fibers.
The straight fibers provide vertical support and help the turf maintain stability under traffic. The curled fibers provide cushioning, recovery, and additional support between the straight fibers. This combination helps the turf remain upright, comfortable, and stable without relying on loose infill.
Low-grade products often use only stiff straight fibers. This may create temporary standing support, but the surface can feel hard, lack cushioning, and lose resilience after repeated use.
2.2 Reinforced Composite Backing System
The backing is one of the most important parts of non-infill turf, but it is often ignored by buyers.
Without infill to help stabilize the surface, the backing must firmly lock the yarns in place and maintain structural integrity over time. High-quality backing should provide strong yarn anchoring, hydrolysis resistance, dimensional stability, and resistance to cracking or delamination.
Vivaturf uses reinforced composite backing structures designed to improve yarn fixation, backing strength, and long-term stability. A strong backing helps reduce yarn loss and supports the overall system performance.
Low-grade backing is often thin, brittle, and heavily dependent on conventional latex adhesive. Under moisture, heat, and repeated use, such backing may weaken, crack, or delaminate.
2.3 Engineered Shockpad for Mechanical Balance
Many buyers overlook the shockpad, but it is essential for field comfort and player protection.
High-quality non-infill turf should work with a proper elastic layer, such as a closed-cell PE shockpad, to control impact absorption and vertical deformation. This helps balance cushioning and support.
A poor system may have no shockpad, or it may use low-grade recycled foam that collapses quickly. Once the shockpad fails, the field may feel too hard, too soft, or inconsistent.
Vivaturf’s sports-grade systems are designed to keep shock absorption and vertical deformation within controlled performance ranges, supporting both safety and sports performance.
