Get filled in on infill

By admin on October 24, 2017

Once you’ve decided which pitch to invest in, it’s time to consider the infill. All artificial grass systems are made up of a base layer, a layer of carpet and some kind of infill material, which helps keep the fibres in top condition. Here’s a guide to all of the different types compatible with your 3G pitch.

Rubber crumb

Rubber crumb, otherwise known as SBR, is the most common infill choice. Anyone who has played on a 3G surface will recognise those small bits of black rubber, generally made by grinding up recycled materials, such as car tyres. Not only is SBR very cost-effective, but it is also extremely hard-wearing – ensuring the infill will perform as it should for the whole of the pitch’s life cycle. On the other hand, there can be concerns about the chemical composition of SBR and some users worry about using recycled rubber within the make-up of the pitch.

Coated rubber crumb

Coated rubber crumb is a technologically-advanced derivative of standard SBR. It is formed by coating the rubber with a material called a polymer, of the type often found in healthcare products, such as replacement heart valves. Wrapping the SBR in this way ensures that absolutely no substances can be released from it, and produces a denser material that also carries a range of playing benefits – including more consistent ball bounce, lower operating temperatures, and reduced levels of infill splash.


EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber with several favourable properties for use in 3G systems. Not only does its elasticity and durability help it to cope well with high levels of play, but EPDM is also a virgin material. This means its first use will be as infill, which can reassure those concerned about using recycled SBR. However, this type of infill can harden over time, and cannot be reused or recycled at the end of its life cycle.


Additionally, there are several types of natural infill available on the market. These are generally made from organic materials such as cork, or coconut husk, which can be directly recycled into the environment at the end of their life cycle. The downside to natural infills is that they vary in quality, and can break down with years of use.

Whilst sporting bodies – such  as FIFA, the RFU or the FIH – may prescribe a certain type of infill in order to obtain specific accreditation, the decision can often come down to preference. At TigerTurf, we’re committed to finding and testing a number of different systems, which helps to ensure that you get the widest possible range of infill options to choose from.
