Artificial Turf Infill

Without infill, artificial grass fibres would lie flat and the backing would shift underfoot; infill weighs the turf down, helps blades stand upright for a more natural look, and provides some cushioning underfoot. Common types include silica sand, rubber crumb, and organic blends such as coated cork or coconut fibre.

Infill settles and compacts over time as foot traffic pushes it down and wind or rain gradually redistributes some of it, so turf that looked full and springy when installed can start to look flatter and feel firmer within a few years. A top-up brings blades back upright and restores cushioning without needing to replace the turf itself.

In direct summer sun, infill also affects surface temperature: darker rubber infill absorbs and holds more heat than lighter sand-based options, which is one reason installers in hot climates often lean toward sand or lighter-coloured blends for areas that will be walked on barefoot. A top-up is typically needed around the five-year mark, sooner in high-traffic areas.
