Non-infill artificial turf has transformed the industry by removing the need for rubber granules or silica sand. However, one crucial step often underestimated in its installation is seam sealing. While non-infill turf eliminates the hassle of infill maintenance, it still requires precise treatment at joint areas to ensure long-term stability, safety, and playability.
Why Seam Sealing Matters
Preventing Separation
Large-scale fields are installed with multiple turf rolls, which naturally create seams. Without reinforcement, these seams are vulnerable to stress from foot traffic, temperature swings, and expansion. Proper seam sealing integrates individual rolls into a unified surface, preventing separation and extending field longevity.
Protecting the Sub-Base
Unsealed joints may act as pathways for rainwater or moisture to penetrate the sub-base. Over time, this can cause base deterioration, swelling, or even turf upheaval. Seam sealing with waterproof adhesives provides a protective barrier, while Vivaturf’s engineered drainage design ensures rapid water dispersion.
Preserving Flatness and Playability
Smooth and even surfaces are essential for sports performance. Seams that are left untreated may collect debris or collapse under pressure, resulting in uneven ball roll or increased risk of player injury. With proper sealing, the turf maintains consistent flatness and ensures reliable athletic performance.
Where Seam Sealing is Essential
Sports fields and large outdoor areas: Football pitches, school playgrounds, and multi-purpose tracks.
Outdoor installations: Constantly exposed to rain, heat, and UV radiation.
High-traffic surfaces: Kindergartens, gyms, and community recreational areas.
For instance, at Zhengzhou Nankai High School, a 7,000 m² Vivaturf non-infill football field was installed using seam tape combined with PU adhesive. After five years of intensive use, the surface remained seamless and durable, still meeting international quality benchmarks.
When Seam Sealing Can Be Simplified
Small-scale applications: Private gardens, balconies, or areas under 20 m².
Indoor facilities: Controlled environments with stable bases, where joint sealing requirements can be reduced.
Professional Seam Sealing Process
Preparation: Clean seams and ensure dry conditions before application.
Adhesive and Tape Placement: Apply PU adhesive evenly, position seam tape, and secure the turf edges.
Compaction: Use heavy rollers to press joints firmly, eliminating trapped air.
Curing and Inspection: Allow adhesive to cure fully, then check adhesion strength and playing consistency.
Vivaturf’s Advantages in Seam Sealing
Advanced Backing: Dual-layer backing increases bonding strength and reduces risk of delamination.
Dense Fiber Coverage: High-stitch density conceals seams naturally for a seamless visual effect.
Integrated Material Supply: Vivaturf provides seam tape and adhesives engineered for full compatibility.
Important Notes: Avoid low-quality adhesives such as silicone or glass glue, maintain installation temperatures between 5–35°C, and repair minor seam issues promptly to prevent escalation.
Final Word
Seam sealing is not an optional step—it is a fundamental requirement for non-infill artificial turf systems. By combining advanced turf technology with proper seam sealing methods, Vivaturf surfaces can achieve a lifespan of 15–20 years, ensuring unmatched durability, performance consistency, and safety for athletes and communities alike.
