When designing a high-performance synthetic turf system, choosing the right artificial grass infill is crucial. Infill materials significantly affect the turf’s durability, shock absorption, ball behavior, and safety. This guide provides a comprehensive look at infill options used in modern artificial turf systems, along with their environmental implications, cost profiles, and real-world performance.

What Is Infill and Why Is It Important?
Infill refers to the granular materials spread between the blades of synthetic grass, serving several functions:
- It helps fibers stay upright.
- Provides impact absorption and player comfort.
- Enhances ball roll and bounce characteristics.
- Contributes to system durability and drainage.
Modern turf systems often use a mix of performance infills and stabilizing sand, depending on their intended application—sports, landscaping, or playgrounds.
Common Types of Infill Materials
1. Silica Sand
A basic and cost-effective option, silica sand infill is often used as a stabilizing base, particularly in landscape and light-traffic areas.
- Pros: Affordable, widely available, UV resistant.
- Cons: Limited shock absorption; can compact over time.
