The flattening risk of non-infill turf is usually not caused by “non-infill” itself. It is caused by weak materials and poor structural design.
Low-grade non-infill turf may have one or more of the following issues:
- Low-modulus fibers that cannot support themselves without infill
- Poor fiber recovery after repeated loading
- Incorrect straight-to-curled yarn ratio
- Weak backing that cannot hold the fiber roots firmly
- Low-quality shockpad with excessive compression set
- Poor installation that causes uneven load distribution
- Lack of third-party testing and on-site acceptance control
In these cases, the surface may look full when new, but after repeated foot traffic, the fibers may gradually lie down and the lower layers may lose resilience. This is why buyers should not judge non-infill turf only by pile height or density.
For high-quality non-infill turf, anti-flattening performance must be designed from the yarn, the backing, and the shockpad as an integrated system.
