Indian Economy Overview • • •

India is one the largest and fastest growing economies in the world Notwithstanding the economic slowdown, India continued to grow at 6% + India's GDP is projected to grow @ 8-10% for the foreseeable future GDP growth rates of the ‘BRIC’ pack

In US$ Billion

Potential for Geosynthetics in India Government of India in the Annual Budget 2010-2011 has ambitious plans for the investment in infrastructure development:  Roads & Highways •

National Highways Development Projects at a glance (NHDP): NHDP envisages :

6-laning 6,500 km 4-laning 17,500 km Upgrading of 20,000 km of National Highways Initiating development work of 1000 km of expressways. The MORTH has plans to build 20 Kms. of new road for the whole year.

The projected investment is about Rs. 8,12,661 Cr. ( USD 179 billion) over a period of six(6) years. Assuming that even 30% of the road stretches use Geo- textiles, this itself will require 46 million sq meters i.e.9500 tons in next 3-4 years. www. terramgeosynthetics.com

Potential in India based on current budgets  Ports •

National Maritime development projects (NMDP):

 India has a 7500 Kms. of coastline  Currently, 12 Major ports (6 each in West & East) & 45 Non major and private

ports are operational.  To provide additional capacity and to upgrade the present infrastructure to international standard, an investment of about Rs.50,000 Cr. (US$ 11 bn) is envisaged in the major ports during the next five(5) years.  Port trust will undertake : - Development of 54 new Berths in next 5 yrs. - Several dredging projects would be undertaken - Road & Rail connectivity projects of over Rs.7,000 Cr.(US$ 1.5 bn) is under implementation

There is huge potential of use of Geotextiles in coastline as it is specifically used for a purpose of Scour protection. www. terramgeosynthetics.com

Potential in India based on current budgets  Railways  Indian Railways is one of the largest railway system in the world  An Expansion of new 25,000 km length is proposed in next 10 yrs. Time  A dedicated freight corridor project estimated to cost about Rs.57,000

Cr.(US$12 bn) is being implementation.  Railways plan development of superfast trains ,350 kmph , for which use of

Geotextiles will be a must

Geosynthetic can play a very vital role in improving the cost effective track structure design.


Potential in India based on current budgets  Airports  India is currently the 9th biggest aviation mkt. in the world.  About 10 major and 40 smaller airports exist

 The passenger traffic is expected to cross

–

145 million per annum by 2010.Cargo traffic will cross 3.3 million M.T. by 2010.

 Upgradation & Modernisation of Airports as per International

standards will be the top priority An investment of Rs.40,000 Cr. (US$ 9 bn) would be made in Airport infrastructure during the period 2006-07 to 2013-14.

What is

Terram

?

TERRAM is a Geosynthetics company dedicated to supply of materials to the worldwide construction industry. • The focus is in the supply of

- Geosynthetics for infrastructure construction - Specialist range of geotextiles for the rail industry - Drainage composites for structural and waste management drainage systems - Geocells for construction where there is need for stabilisation or Reinforcement


GEOSYNTHETICS Definitions : (ASTM D4439) Geosynthetics – A planar product manufactured from a polymeric material used with soil, rock or other geotechnical related materials as an integral part of a man-made project, structure or system This term encompasses Geotextiles Geogrids Geonets GeoCells Geomembranes Geocomposites… etc.

Geosynthetic functions


Separation • Prevents contamination of granular material • Reduces loss of granular material into sub-base • Makes spreading of fill easier • ground Minimise need for excavation or treatment of existing • Fill can be placed over soft ground


Filtration •

Geotextile Allows Controlled passage of excess Pore water from the soft subgrade.


Confinement •

Geotextile restrains lateral movement of the material at the bottom of the granular layer.


Nonwoven Geotextiles (GT) Definition :

A flat structure of synthetic fibers randomly laid manufactured by bonding them together – mechanical bonding , thermal bonding or chemical bonding .

Erosion Control - Shore/Costal Protection - River & Canal Bank Protection - On-shore structures - River Revetments - Dams & Flood Defence Bunds


PROBLEMS: 1.

River and Canal Banks are subject to wave actions, i.e. reversing flow conditions .It is this dynamic erosive force that undermines bank stability and effects channel flow and/or navigability

2.

On Coastlines, the three key agents of erosion are : - Waves & Tides Eroding the shoreline - Waves and tidal scour take the eroded sediment away from the coast - Currents sweep the displaced material out to the sea.

Advantage of Geosynthetics 

Geotextile filter, being permeable allows water to pass through releasing water pressure but prevents soil erosion.



With specialised built- in factory –controlled Hydraulic and filtration properties a single layer of geotextile can replace a succession of stone filter layers.



working under water is much easier because the filter system can be assembled above the water and lowered into position with less time being used.



Geotextiles is easier to install either manually or mechanically.


Required characteristics of the filtering geosynthetic The filtering geosynthetic was designed in order to achieve the following purposes: Good filtering capacity (Appropriate Hydraulic properties) - Impact resistance

(must be Robust)

- Holding resistance - Resistance to the construction stress

? ? ? Geosynthetics - Why rem ains Untapped Potential ? Or - Reasons for Low Growth in India ?


Hurdles Observed - Lack of proper awareness and Close interactions and participation between manufacturer/Supplier, Design consultant/specifiers & end user (Civil Contractors, Govt. authorities etcs.).

- Non availability of dedicated Indian code i.e Dependency on foreign code - State level agencies lack awareness and many of Govt. agencies remain oblivious about the new products including Geo-synthetics due to improper information , lack of knowledge for advantages of use, low budget etc. - Preparedness of end users designers to go with traditional ways or custom made solutions. - Lack of proper testing and evaluation - Non-availability of trained and experienced Staff. www. terramgeosynthetics.com

ome Thoughts / Visions / Paths - Unified Indian code, Specification is the need of the hour. - The use of Geosynthetic should be mandatory as it’s now proven technology – This means inclusion in all SOR ’s , guidelines etc.

- To conduct practical training, Seminars and Exhibitions. - Manufacturer should step forward with best quality with proper testing at economical cost – This also means best cost needs high volumes as well. - Availability of proper testing at National level. - To generate technically trained personnel. - Geosynthetic should be included as a subject or course at BE level.
