Infill is the material layer that sits between the synthetic turf fibers — typically silica sand, crumb rubber, or a hybrid combination — and it performs several critical functions simultaneously. It supports the turf fiber upright so the pile maintains its appearance and soft feel. It adds weight to the system so the turf backing stays in position. It manages heat retention and surface temperature. It contributes to drainage performance by creating a permeable layer through which water and pet waste liquids can move toward the base. And in athletic applications, it provides the shock absorption and traction that make the surface safe for play.
Over time, infill migrates. High-traffic paths — the route from the back door to the fence gate, the area around the pool steps, the goal area on a community athletics field — lose infill through displacement from foot traffic. Heavy rainfall events in Fort Bend County can also displace infill, particularly near edges where the base grade directs water. And infill settles and compacts with age, reducing the volume available to support the pile even in areas that have not experienced displacement.
The result of infill depletion is visible: the pile flattens and mats in high-traffic zones, the surface feels less resilient underfoot, and in severe cases the turf backing becomes visible between flattened fibers. Drainage performance may also decline as compacted infill near the surface impedes water flow into the base layer.
Artificial Grass of Missouri City provides infill replenishment as a standalone maintenance service and as part of comprehensive maintenance visits. The process begins with an assessment of the current infill condition — where has depletion occurred, how severe is it, and what infill type was originally installed. Replenishment is then completed with matched or compatible infill, distributed to restore the original volume profile across the surface, and worked into the pile with a power broom to achieve even distribution and restored fiber orientation.
