When purchasing non-infill artificial turf, seam performance should not be evaluated only by looking at the grass fibers.

Ask the manufacturer for technical information covering the complete system.

Important parameters include:

Parameter	Why It Matters
Seam strength	Indicates resistance to joint separation
Tuft bind / pull-out resistance	Indicates how securely yarn is retained
Backing tensile strength	Indicates backing durability
Adhesive bonding strength	Important for long-term seam integrity
Hydrolysis resistance	Important in humid and wet climates
Dimensional stability	Helps control thermal movement
UV/weathering resistance	Important for outdoor applications
Water permeability	Helps prevent prolonged moisture exposure
Seam tape compatibility	Supports reliable repair and installation

For projects in Europe and North America, test methods and acceptance criteria should be specified according to the intended application and project specification rather than simply converting one Chinese parameter into an overseas standard.

How to Prevent Seam Damage in the First Place

Repair is important, but prevention is better.

Before installation

Check:

• Substrate flatness
• Drainage
• Moisture conditions
• Turf roll condition
• Temperature
• Adhesive compatibility
• Seam tape specifications

During installation

Avoid:

• Excessive stretching
• Dirty bonding surfaces
• Uneven adhesive application
• Insufficient rolling pressure
• Premature traffic
• Installation during unsuitable weather

During maintenance

Inspect seams regularly, especially:

• Field boundaries
• High-traffic areas
• Goal mouths
• Turning zones
• Around drainage points
• Areas exposed to strong sunlight

A small seam opening is much easier to repair than a large section of separated turf.
