Performance infill

Pitch Construction

Next to deciding which type of artificial grass is most suitable for your needs, choices for the performance infill layer should also be made. Infill material is an essential component in artificial turf systems and ensures that the turf fibres remain upright to resemble natural grass. The performance infill ensures that the players shoes have a good grip and can also reduce the strain on muscles and joints by acting as a cushion along with maximising sliding characteristics. The infill layer has various options and each infill has its specific characteristics.

The infill base is often formed by a sand stabilization layer in combination with a granulate that adds additional sport-technical properties to the system. When choosing your infill check for available quality reports for the infill; a poor-quality synthetic infill can (in the long-term) cause major problems in the field. The infills in the GreenFields systems have been extensively tested for performance and durability internally, but also externally certified by independent test institutes.


Natural infill

Natural infills are a good alternative for short-pile synthetic grass, densely tufted or with fibrillated or texturized yarns that hold the infill together but require more maintenance.


  1. Nature

    Cork (described as Nature in our systems) is the most used natural infill material. Cork delivers good sport-technical performance, but because it is very light it easily migrates from an open artificial grass surface.

  2. BioBlend

    BioBlend is a mixture of cork and granulated corn cobs which increases the bulk density.

  3. GreenFill

    GreenFill is a bio-degradable alternative which will degrade in only 6 months’ time if it ends up in the soil around a pitch.

Synthetic infill

  1. EPDM

    A virgin material closely related to SBR is EPDM (both thermosets), which delivers good sports performance and is very durable in the long term.

  2. TPE-B

    TPE (a thermoplastic) is also a good alternative that is widely used, available as a solid granule (B) or hollow in a cylindrical shape (H).

  3. TPE-H

    The cylindrical shape (H) has a lower bulk density so requires less material in the installation.

Recycled infill

  1. SBR

    The most common recycled infill material generally used is SBR (Styrol Butadiene Rubber). SBR rubber infill is made from grinded old rubber products such as car tires.

  2. SBR-C

    BR is also available in a coated version in various colours: SBR-C.

    After a thorough quality check also synthetic infill from old pitches can be used for new applications.
