AstroTurf® RootZone® – The Game Changer

Infill is the rubber (and sand) which are a part of synthetic turf fields designed to mimic the ground. In fact, there are nearly 20,000 ground up car tires in a typical field. Infill flyout is a huge issue with fields in terms of safety, durability, and performance of the field.

As you can see from the photo below, this field is brand new and already looks to be having issues.

Competitor systems have infill splash out without RootZone technology

Now, take a look at what you get with an AstroTurf surface featuring RootZone and why it makes all the difference.

AstroTurf surface featuring RootZone

Making a superior turf system is not only complicated and difficult; it demands sophisticated technology for the safety and performance of athletes.

AstroTurf has brought its long history of innovation, its industry-leading manufacturing base, and zeal for perfection to a significant problem afflicting the turf industry — infill instability. The result, a game-changer, is the RootZone — perhaps the most significant improvement in turf technology in the last decade.

RootZone is a proprietary system which provides a thatch layer to the turf system and helps stabilize the infill. The need for stabilizing the infill is not a new discovery or new problem. Third Generation (tall pile, rubber-filled systems) have struggled with this problem since the first introduction of these systems in the late 1990s. In fact, the original version of the RootZone was introduced by AstroTurf technical experts in 1998.



  1. Loose rubber or other infill materials tend to splash or fly-out when players cut, fall or slide on the turf.
  2. Loose infill materials creep or migrate — generally moving from the center of the field to the edges.
  3. In high-use, high-wear areas, the infill tends to be displaced, especially when constantly kicked (corner kick areas, penalty areas, soccer goal areas, lacrosse creases, football extra point spots, etc.).




  1. The RootZone significantly reduces rubber splash or fly-out because the granules are stabilized within the nylon fibers.
  2. The RootZone significantly reduces rubber or infill migration or creep because the granules are stabilized within the nylon fibers. Without this kind of movement, the infill remains uniform, predictable, and safe. Safer, because the surface is consistent and uniform (players do not adjust their gait due to a subconscious concern about unpredictable footing and energy restitution). Safer, in terms of shock absorbency, especially in high-use areas where shock absorbency is critical. In spots where infill migration has occurred, the infill will be thinner and Gmax will be higher, a very negative consequence for players. (Gmax tests per ASTM F-1936 on non-stabilized infill systems often indicate additional maintenance to be necessary to provide adequate Gmax in high-use areas).
  3. The RootZone reduces rubber infill displacement in high use areas because the granules are stabilized within the nylon fibers. This is the most difficult challenge for a RootZone simply because these areas are hit with such force and frequency. Even with the RootZone, special maintenance should be performed to keep these areas infilled properly.

The RootZone infill stabilization system is available only from AstroTurf. We invented it, patented it, improved it, and have applied for additional patent protection.
