What is a synthetic turf pitch?

A synthetic turf pitch is a synthetic carpet made up of polyethylene yarn on a triple backing latex system with infill consisting of silica sand and SBR rubber, laid on a specially prepared base with an integrated drainage system.

There are two types of carpet yarn available, Monofilament yarn and Fibrillated yarn.
What is the difference between Monofilament yarn and Fibrillated yarn?

Fibrillated yarns are manufactured from thin sheets of plastic that are slit and twisted to form thicker fibres that form the pile of the carpet. Over time and as a result of constant play on the surface these fibres slit to form smaller finer fibrils which break down and therefore reduce the lifespan of the pitch. Monofilament yarns are manufactured as individual strands that are piled together to form the tufts. This type of yarn is the most popular and best available as it is very resilient and durable. It does not slit like fibrillated yarn and therefore has a longer lifespan. Coyle Sport Surfaces use only Monofilament Yarns in their carpets manufactured by ACT Global Sports.

How is the carpet installed?

The carpet is manufactured in rolls, 4m in width. These are put in position and rolled out and using seaming tape and a high strength adhesive that has been formulated for the synthetic sports market to take the wear and tear, the joints are glued and left for 24 hours for the adhesive to set. The correct infill of sand and SBR is then massaged into the carpet using the latest SMG technology ( SMG Sandmatic) which has been designed for this sole purpose. Coyle Sport Surfaces fitters are specially trained in the installation of synthetic turf surfaces and all pitches are fitted as per ACT Global Sports specifications.

What does the infill consist of?

In our monofilament yarn carpets we use two specialised in fills. The first layer consists of 80% rounded washed silica sand, which acts as a ballast, keeps the fibres upright and assists in the drainage. The second layer consists of styrene-butadiene rubber (SBR). The granules are black in colour and produced from recycled tyres, which are treated and cleaned and reformed into particles 0.5mm to 2mm in size.

The combination of both the sand and SBR in fill, support the pile of the carpet and help it to remain vertical, provide cushioning to the surface and provide weight to keep the carpet in place. The amount of sand and SBR used depends on the pile height of the carpet which range from 35mm up to 70mm. The height of the fibres above the infill is normally 20mm and this ensures that the surface provides the desired playing characteristics.

How is the sub-base constructed?

The sub-base is constructed from unbound graded aggregates that provide an inert, stable and free draining structure for the synthetic surface to be laid on. It is laid using three layers of clean angular stone which is rolled, with the final layer levied with laser controlled equipment to with in 1mm of final level.

What drainage system is used?

The drainage system is designed to remove all surface water from the playing area at a sufficient rate to prevent flooding and to ensure that excess water is not allowed to build up within the sub-base causing a reduction in its structural integrity.

The drainage system consists of a series of lateral drains laid beneath the pitch, at 5 metre centres and these are connected to the main drain which discharges excess water to a suitable outlet. The main drain is located outside the perimeter edgings of the pitch. The correct construction of the sub-base and drainage system installed is the most important factor in the installation of a synthetic turf pitch.

What floodlighting system?

Light is measured units called Lux. The higher the Lux level the stronger the light on the playing area will be. When choosing floodlighting it is important to have the correct illumination on the pitch. A training area or small 5 a side will typically require a lighting system of 150 to 250lux. A larger pitch used for competitive games will require a lux level of 300 to 500 lux. Any sport using a small ball, eg. Hurling or Hockey requires a minimum of 500 lux. There are other factors to consider when choosing a floodlighting system, such as light pollution, excess over spill, height and position of poles and maintenance costs. Coyle Sport Surfaces provide professional advice on the correct floodlighting system to use.

Is Maintenance required on synthetic turf surfaces?

It is essential that a maintenance programme is put in place in order for a synthetic turf pitch to retain an acceptable level of performance and also to extend the lifespan of the pitch. See our section on Maintenance for more detailed information.
