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.
Our Services | 3G
Blakedown Sport & Play is of the UK's largest and longest established construction contractors specialising in synthetic sports surfaces. We have been in business for more than fifty years - longer than 3G artificial turf has been on the market - and our clients include clubs, councils, universities, colleges and schools across the UK.
We offer the complete package for 3G pitch construction, literally from the ground up, including design, planning, groundwork, installation, and ancilliary works including fencing, floodlighting, and peripheral landscaping.
Choice of 3G surface
The two main variables in 3G systems are pile height and yarn type. The standard pile heights of 3G turf are 40mm, 50mm, 60mm, and 65mm. The 65mm length pile would be suitable for rugby, the 40mm suitable for hockey.
The two main yarn types are monofilament and fibrillated: a monofilament yarn is manufactured as a single fibre string which is nominally preferred for higher specification football and rugby pitches (FIFA Quality, for example). Fibrillated yarn is manufactured as a fibrillating fibre tape, nominally offering greater durability against frequent and intensive use (a 5-a-side facility, for example).
3G pitch construction
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.
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.
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.
