Artificial Turf

Postby Prasanth » Thu Dec 29, 2011 6:58 pm

Artificial Turf is a surface manufactured from synthetic fibres made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. The main reason is maintenance — artificial turf resists heavy use, such as in sports, better, and requires no irrigation or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy.

A common misconception is that the new synthetic grass is similar to the household carpet. In fact this intricate system involves properly constructing a porous sub base, and using turf with holes in the back, then the product is filled with sand/rubber granule mix which we call infill. Artificial turf, also known as synthetic turf, has found a prominent place in sports today. Manufactured from synthetic materials, this man-made surface looks like natural grass. With the international sports associations and governing bodies approving the use of artificial surfaces, sports like football and hockey, which were originally played on natural grass, have moved to these artificial sports pitches. So, next time, you find players playing on an artificial hockey pitch, do not be surprised.

Artificial turf has been manufactured since the early 1960s, and was originally produced by Chemstrand Company (later renamed Monsanto Textiles Company). It is produced using manufacturing processes similar to those used in the carpet industry. Since the 1960s, the product has been improved through new designs and better materials. The newest synthetic turf products have been chemically treated to be resistant to ultraviolet rays, and the materials have been improved to be more wear-resistant, less abrasive, and, for some applications, more similar to natural grass.

Synthetic turf is an evolving industry and is frequently used as an alternative to natural grass. Drainage is a critical design element for any synthetic field. Lack of proper drainage creates surface run-off issues and reduces playing time.Stone base drainage designs are expensive and have performance limitations. Typical stone drains require from 6-8 inches of aggregate, extensive site excavation and high transportation cost to haul stone to the site and to remove excavated soil from the site. Stone bases are hard, rough surface that provide poor footing, resulting in potential injuries to players.

The infill holds and absorbs water which eventually drains through the holes to the sub base system. Some water will run off the top under heavy rains just the same as natural grass. Correctly installed synthetic grass will drain quicker than natural grass.A drainage system is provided for a synthetic grass turf assembly having a flexible and water permeable sheet backing for installation on a supporting soil substrate to provide a game playing surface. The draining system of the present invention prevents water from accumulating on the turf surface, which could cause the top-dressing layer to “float” and be moved by inundation.

As mentioned above in the installation process, the drainage system is fixed on the sub base layer. It is installed at a depth of 50-75 cm from the surface of turf. The sub base layer is filled in two phases. The lower portion of sub base is filled in inclination with the pebbles. In order to make the pipe in position a sand layer is provided on the top. At middle above the sand layer a long pipe is installed. The diameter of the pipe varies from 10-20 cm and it has aslope of 1/500 to 1/750 along the length of the ground.

Above the sand layer separator geo membrane and above the pipe filter-geo membrane is installed. The geo membrane is laid at a slope of in 1/20. The remaining sub base is filled with coarse aggregate or pebbles and the base corse is filled with sand and above the prepared ground the turf is fixed.The water from the grass fibre passes through the infill and then through the base corse to the sub base collected through the aspirator geo membrane to the filter geo membrane, then it flows out through the pipe. The pipe leads out of the stadium.

In addition to this the drainage facility provided on the periphery is also present at the ground. Thus any chance of water logging conditions is avoided

MAINTAINANCE

With our synthetic turfs you will never have to mow, irrigate or fertilise your surface ever again. However, you will have times when you will want to clean the artificial turf fibres or need to clear off fallen leaves in the fall. There are simple procedures to be followed in order to maintain your artificial turf in an optimal condition.The recommend weekly servicing includes: brushing and clearing the turf of any dirt – scraps, garbage or leaves. Once a year, a special servicing team should check the condition of the surface and, if required, conduct all the works necessary for increasing its quality and life-span.

Routine maintenance generally includes keeping the surface clean of debris, especially that which may decay into the infill, and occasionally sweeping the fibres up to revitalize the appearance of the lawn.Rain is your best cleanser. Rainfall gently cleans the turf fibres of dust, pollen and airborne pollutants in a way that is difficult to duplicate in any other fashion. In areas where rainfall is scarce--or during prolonged periods of drought--an occasional water flush is beneficial to soak and thus cleanse the turf system ( only if water restrictions allow ). This procedure is recommended for all turf systems.

Keeping a beautiful green playing field for sports like soccer, football, and baseball is important and requires lots of work. Watering or irrigating the surface is done for it. It is done by two ways;

1) Water Reel system and
2) Underground sprinkler system.
