Infill is the part of an artificial turf system most homeowners never think about — until it's depleted, and the yard suddenly feels different underfoot or starts draining poorly. Here's what it actually does and why it's part of routine turf maintenance, not just installation.
What infill actually does
Infill is the granular material spread between the turf fibers, usually silica sand or a sand/rubber blend. It does three jobs at once: it weighs the turf backing down so it lies flat, it helps the fibers stand upright instead of matting over, and it cushions the surface for foot traffic and play.
Why it depletes over time
Infill migrates and compacts naturally through normal use — foot traffic, pets running around, rain, and even wind gradually shift it toward the edges of the yard or compress it down. A yard with heavy daily use (kids, dogs, or both) loses usable infill faster than a lightly used side yard.
Signs your infill needs attention
- Fibers lie flat and don't spring back after being walked on
- The turf backing is visible or feels thin/loose underfoot
- Drainage has slowed noticeably, with water pooling after rain
- The yard feels harder underfoot than it did when it was installed
Cleaning and infill go together
This is why infill work is usually bundled with a deep cleaning rather than treated as a separate service: the same process that extracts debris and pet waste also redistributes and levels existing infill, and tops it off where it's gotten thin. Skipping this during routine cleaning is a common reason turf starts to look "tired" a few years after installation even though it's being rinsed regularly.
How often it needs replenishing
Most yards need infill levels checked and topped off roughly once a year, more often for high-traffic yards, dog runs, or commercial/pet-facility installations. It's a quick add-on during a scheduled cleaning rather than a separate visit.
