One of the most common questions buyers ask is whether non-infill artificial grass needs to be filled after installation. The answer is yes—but not in the way many people think.

Unlike traditional artificial turf systems that require silica sand and rubber infill across the entire surface, non-infill artificial grass does not require performance infill. However, proper seam joining is still essential whenever multiple rolls of turf are installed together.

Instead of filling the surface with sand or rubber granules, installers use specialized seam tape and polyurethane (PU) adhesive to create a secure, nearly invisible connection between turf sections. This ensures structural stability, consistent performance, and long-term durability.

Understanding the Difference Between Surface Infill and Seam Joining

Many buyers confuse surface infill with seam treatment, but they serve completely different purposes.

Traditional infill turf relies on sand and rubber to:

• Hold fibers upright
• Provide cushioning
• Stabilize the playing surface

Non-infill artificial grass achieves these functions through its engineered construction, including:

• High-density straight and curled yarn combinations
• Self-supporting fiber technology
• Engineered backing systems
• Integrated shock absorption

Because these performance features are already built into the turf, no sand or rubber infill is necessary.

However, whenever two rolls of turf meet, the seams must still be securely joined to create one continuous surface.
