The Evolution of Artificial Grass – 4G

The Evolution of Artificial Grass: 4G non-infill Sports Pitches

3G Artificial Turf

3G sport pitches are currently infilled with rubber crumb, spread all over to improve the surface. It is fitted with an underlying drainage system. These sport pitches are approved and recognised by accredited and governing bodies in the UK such as; FIFA and FA.

The rubber pellets/crumbs are supplementary to the synthetic turf, providing better grip and a smoother playing surface for players. Though, the rubber crumbs need to be added frequently to the turf, they are messy and are likely to get everywhere, even after the game. This can prove to be disadvantageous when trying to keep costs down, cleaning and maintenance expenses would need to be considered when opting for 3G pitches.

The origin of the rubber crumb has been under investigation for several years due to health concerns, with many claiming that they are widespread with carcinogens. Rubber crumbs used for 3G sport pitches are often reclaimed from old recycled tyres.  Several studies have explored the above claims, but then again have all lead to inconclusive results, suggesting that further investigation is required into the relationship between rubber pellets and overall health. These studies are principally important when exploring options for play areas and sports pitches aimed at children.

What is 4G Artificial Grass?

4G known as ‘fourth generation’ artificial turf refers to an improvement and innovation in technology on 3G (‘third generation’) artificial grass. The technological advancement refers to how closely the pitch replicates playing sports such as; football and rugby on real grass. The non- infill feature means that the synthetic turf can be laid without the addition of rubber crumb.

Why is 4G non-infill Artificial Grass preferable?

4G non-infill Artificial Grass is an evolution in technology, it delivers the most accurate playing experience to traditional turf.  It has great weather proof qualities, water can drain speedily owing to their several porous layers. Delays are kept to a minimum because there is little need to cancel matches due to the weather. Training on 4G pitches gives players the chance to better equip themselves for the same playing conditions they’re probable to experience on match day – irrespective of the weather.

As no rubber crumb is required there is an obvious financial and time advantage. Once installed, it requires little care and will not cause additional mess or dust as a by-product.

As it is a new product although it meets the criteria of synthetic sports pitches, 4G non-infill grass isn’t currently accredited by regulatory bodies in the UK.4G Artificial Grass
