What is a 3G Pitch?

3G pitches are the most significant and successful development in synthetic surface technology designed for football and rugby at both competitive and recreational levels. In 3G turf, the pile (artificial grass ‘blades’) is supported by a thin base layer of sand, and by an infill of rubber crumb. The pile height ranges from 40mm to 65mm depending on which primary sport is to be played on the surface.

In construction, the 3G sports turf can be laid onto various bases from the ‘Dynamic System’ of stone base with or without a shockpad, to the top specification ‘Engineered System’ of stone base, porous tarmac layer, and shockpad.

Playing Surface
Third Generation surfaces have been developed to replicate natural turf, with outstanding performance, reduced ball bounce, and low resistance to turning and sliding – offering greater safety to players, more realistic conditions, and greater durability. Blakedown offer a choice of fibrillated or monofilament yarns with Low Slide Resistance technology. The 3G turf is supported by an infill of sand and rubber crumb helping to support the turf pile, keeping it upright, while minimizing ball bounce.
Shockpad
A shockpad is installed beneath the playing surface to cushion the player upon impact with the ground. This is especially important for the shorter pile turfs designed to speed up football play and allow for hockey play, as the protective capabilty of the turf is less substantial in shorter pile lengths.
Engineered layer
The 3G sports turf can be laid straight onto a stone base with or without the use of a shockpad. This is called a Dynamic system. The optimum construction build-up for 3G pitches is to use a single or double layer of porous macadam to offer a much greater degree of stability. This is called an Engineered system.
Stone layer, Textile Membrane, and Soil Formation
The base construction of a 3G pitch is comprised of free-draining stone layer and textile membrane on top of prepared soil formation.
