Geotextiles: Enhancing Soil Stability and Infrastructure Performance

Geotextiles play a crucial role in reinforcing weak soil, facilitating drainage, and protecting embankments. By preventing cracks, they enhance road performance, lower maintenance costs, and ensure a smoother ride. With a global geosynthetics consumption of approximately 3 billion square meters, the usage of geotextiles has become prevalent worldwide since the 1970s. In India, there is a significant opportunity in road and railway infrastructure, requiring substantial investments for expansion and improvement. Key regions face challenges such as coastal erosion and riverbank protection, presenting further avenues for geotextile applications.

  1. Geotextile….. Reinforces weak soil Facilitates drainages Protects embankments Prevents cracks

  2. Leading to….. Better road performance Lower maintenance cost Smoother ride

  3. International Usage 2015 estimate – 4.5 billion sq.met CAGR ~ 14.5% Global Geosynthetics Consumption ~ 3 Billion Sq. Mtrs Source: Geosynthetics – David Cook (2003), Freedonia Group (2009)

  4. Geotextile Usage prevalent All over the world since 1970s It has reached a stage: “Whenever earth is moved Geosynthetics is used” India @ 2% of World Consumption

  5. Opportunity 1 – Roads Road Network: 4.69 Million Km • STATUS • Road transport share in GDP 4.7 % ( 2009-10) • India building new highways ( 2011-12) 10.39 Km per day. Source: MORTH / FICCI

  6. Opportunity 1 – Roads Contd… CAGR 4.2% Huge Gap Growth of Road Network in India Road Density per 1000 people • According to estimates, the road sector in India will require investments in the range of US$ 75-90 billion over the next five years. • Source: Consolidated FDI Policy, Department of Industrial Policy & Promotion (DIPP) thru http://www.oifc.in/sectors/infrastructure/roads/Morth Rs250 Cr worth Geotextiles required at 10% penetration

  7. Opportunity 2 – Railways • STATUS • Track length 1.08 Lac Km • Broad Gauge constitutes 79.5% of network • 11000 trains running every day (7000 passenger trains) • 13 Million passengers travelling daily • New Track Construction: • Dedicated Freight Corridor • Eastern Corridor 1839 Km • Western Corridor 1483 Km • Existing Track Maintenance • Track Stabilization • Mud pumping • Embankment • Drainage Railways to spend Rs. 5 Lac Cr in 12th Five year plan (2012-17) Source: Indian Railways Website

  8. Opportunity 3 – Coastal Protection • STATUS • Coastal line ~ 7500 Km • 24% Coastline impacted by erosion* • Area lost or seriously impacted by erosion ~ 450 Ha per year • Business potential Rs 300 Crs. • * ADB Consultant Report

  9. Opportunity 4 – Ports • Major Ports 13 • Minor Ports 187 • Port Traffic by 2020 2500 Million Tonnes (present 800 MnT) • The Shipping ministry will invest Rs.73,793.95 crore for development of various projects in the port sector as part of the 12th Five Year Plan.

  10. Opportunity 5 – River Bank Protection Many tenders released worth of several crores for geobags. • Assam erosion since 1954 • Total Area eroded 425900 Ha • Rate of erosion 8500 Ha/yr • No of Villages lost to erosion 4521 • Population affected 9 lac • Important town / sites / heritage location affected 18 Source : ADB Consultant Report

  11. Opportunity 6 – Airports • No. of Airports 136 • Domestic Passenger traffic by 2020 180 Million (100 Million) • Upgrading 35 non-metro airports at estimated cost of around US$ 1 billion Source : Airport Authority

  12. Government supports… Textile Ministry • Development of Centre of excellence for Geotextiles, BTRA / ATIRA • Support for drafting Indian Standards • Awareness creation (FICCI, CII, CoE) • Incentive for Manufacturers under TUFS / TMTT Ministry of Roads • Code for Geotextile MORTH  Section700 • IRC code 59 - Guidelines on geotextile usage State PWDs • Specified in Schedule of Rates – 12 states BIS • Standards – urgently required

  13. Forging partnership…. Creation of common Geotextile platform
