The Indian Economy Grew at an annual rate of 9% before the
global economic meltdown
Economy growth for 2008 - 09 --- 6.7 %
(due to Global Crisis)
Economy growth for 2009 - 10 --- 7.2 %

Growth projected 2010 - 2011 --- 8.5 %
Growth projected 2011 - 2012 --- 9.0 %

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

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.

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.


 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.



 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 products at a Glance


Geosynthetic functions


Separation
• Prevents contamination of granular material
• Reduces loss of granular material into sub-base
• Makes spreading of fill easier
• Minimise need for excavation or treatment of existing
ground
• 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.

River Revtments

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 (Good Puncture & Tear Strengths)

Terram B1, C1 ,D1 & E1 Terram 1B1, 1C1, 1D1 & 1E1

Terram 1BZ Terram DC-1C, DC-1D & DC-1E


Advantages

Geotextile filter is a very important component of Drainage
Composite. The Heat-Bonded geotextile on Terram 1BZ outperforms
other geotextiles by providing:-

• Higher chemical resistance
• Higher modulus
• Higher available strength at working strains
• Higher elongation at break
• Higher resistance to installation damage
• Constant hydraulic properties over a period of time

Geosynthetics

- Why remains 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.

Some 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.
