2.  Technical textiles that improve engineering
performance of the soil
 Either made of synthetic polymers
(petrochemical derivatives) or of natural
fibres (jute, coir)

3.  Use of jute for solving soil-related problems
is not a new concept
 Jute hessian was applied successfully on Road
side earlier in Indian subcontinent in 1934
and in Myanmar during the 2nd World War
 First concerted effort to promote use of Jute
Geotextile took off in 1980s

4.  High moisture absorbing capacity
 Excellent drapability
 High initial tensile strength
 Low extension at break
 High roughness co-efficient
 High spin ability
 Bio-degradable
 Renewable resource, easily available
 Economical
 Eco-friendly

5.  Separation
 Filtration
 Drainage
 Initial reinforcement

6.  Segregates two layers, preventing
intermixing
 Facilitator to natural consolidation of soil

7.  Two contrasting functions -
 soil retention
 allowing pore-water through and along the fabric
 Addressing 2 related phenomena –
 clogging
 blocking

8.  Acts as a drain within its own thickness.
 Permittivity and Transmittivity of JGT are
high

9.  Acts against rotational slides, lateral dispersion
and vertical subsidence
 Exerts confining action on soil
 Partially absorbs effective stress,
preventing shear failure.

10.  Slope management
 Protection of river bank
 Strengthening of road
 Stabilizing embankments
 Prevention of railway track subsidence
 Consolidation of soft soil
 Control of surface soil detachment

11.  Loss of strength of JGT after a year
is NOT a deterrent –
by that time, JGT provides
a self-sustaining sub-grade for most soils
 The gain in strength of the sub-grade
compensates the loss of strength of JGT
within the same time frame
 With the passage of time
soil dependence on JGT for stability decreases

12.  Economical
 Easily available
 Can be tailor made to meet the criteria of retention and permeability.
 Precise control on quality and workmanship possible.
 Quicker execution time.
 More drapability than any other geo-textile.
 Provides a sustainable and Eco-compatible solution.
 Conducive natural protection against erosion through quick growth of
vegetation cover.
