Next Generation Artificial Turf
Next Generation Artificial Turf
With growing number of athletes
and other sportspersons, the available playground
and stadium facilities are becoming increasingly
inadequate to meet the current and future
needs. Several facilities are in need of upgrading
and some additional fields are also required.
In either case, choosing synthetic
turf over natural grass fields can
be cost-effective and also beneficial. Synthetic
turf is today favored in the
design of professional athletic and sports
fields and the products have also evolved
dramatically during the last several years.
The next-generation products are usually composed
of a thermoplastic fiber that is tufted and
filled inside with rubber or sand or a combination
of both. Synthetic turf is
also beginning to usurp natural grass in other
applications, such as landscape planting islands,
road medians and several golf courses.
There are several distinct
advantages using synthetic turf
as compared to natural grass. Artificial
turfs are maintenance free in
the sense they require no mowing, watering,
fertilizing, or re-seeding. Periodic maintenance
only entails brushing and occasional vacuuming
- and that too using a hired equipment. The
typical sand-based soccer/football field can
use between 2.5 million and 3.5 million gallons
of water per year. The reduced maintenance
expenses and other concomitant costs for supplies
such as fertilizers, herbicides, and pesticides
- several users have reported savings of as
much as $30,000 to $60,000 per field, per
year. There are also the environmental advantages
arising out of reduced water use. The removal
of significant amounts of fertilizer and pesticides
means less chance of contaminating groundwater.
So, we have safer field conditions for children,
pets, and wildlife. It should also not be
forgotten that synthetic turf
is commonly made of recycled materials. Barring
any restrictions imposed by local bodies,
synthetic turf is available
for use at all tomes and round the year. Artificial
surfaces do not become muddy and unusable
in wet weather. It is reported that the artificial
turfs were safer because playing
on them resulted in fewer injuries, especially
knee injuries. This situation has further
advanced in recent years with the introduction
of further improved manufacturing and installation
procedures. Some recent studies indicate that
these latest artificial surfaces are showing
still lower injury rates than even playing
on the earlier types of artificial surfaces.
With the maintenance savings, increased playability,
all weather uses and their associated increased
revenues, artificial turf will be the norm
of the next generation and generations to
come.
David Chaney headed the team
of researchers who were responsible for creating
the artificial turf. In 1965,
artificial turf was installed in the newly
built Astrodome in Houston, Texas. It was
thereafter that the artificial turf gained
prominence. By 1970s, they became widespread
and were installed in both indoor and outdoor
stadiums that were used for baseball and gridiron
football in the United States and Canada.
The 21st century brought with it new artificial
surfaces that used sand and rubber infill.
These next generation turf brought to the
fore the concept of artificial grass which
are almost indistinguishable from a distance.
However, it will be untrue
to say that artificial turfs
are without any disadvantages. The cuts, abrasions
and burns caused on the artificial turf are
of a greater degree when compared to natural
grass. This is because of the friction caused
between turf and the human skin. Research
has shown players who play regularly on the
artificial turf suffer from
a medical condition known as 'Turf Toe. Some
varieties of artificial turf require infill
of silicon sand or granulated rubber that
is made from recycled car tires. These materials
usually carry heavy metals which can affect
the water table. The artificial turf is known
to become much hotter under the sun when compared
to natural grass.
