STANDARDIZATION OF
GEOSYNTHETICS
1
 GEO-TEXTILES ARE FABRICS (WOVEN, NON-WOVEN,
KNITTED OR COMPOSITES) USED IN, WITHIN OR
BENEATH THE SOIL.
 THESE CONSIST OF MAINLY THE TEXTILE MATERIALS
MADE OF POLYESTER, POLYPROPYLENE, GLASS
FIBRES, JUTE AND COIR.
 JUTE AND COIR GEO-TEXTILES HAVE ADDITIONAL
ADVANTAGE OF BEING ENVIRONMENT FRIENDLY AND
BIODEGRADABLE WHICH ARE MAINLY USED FOR
PREVENTION OF SOIL EROSION THROUGH
VEGETATION.
2
 GEO-TEXTILES HAVE A LARGE POTENTIAL FOR USE IN INDIA.

THE INDIAN RAILWAYS ALONE HAS IDENTIFIED ABOUT 20000
KM OF RAILWAY TRACK FOR STABILIZATION.
 THE NATIONAL INTEGRATESD HIGHWAY PROJECT LAUNCHED
BY THE PRIME MINISTER ENVISAGES ENORMOUS USE OF
GEO-SYNTHETICS.
 THESE PROJECTS HAVE LEAD TO HUGE DEMAND AND
CONSUMPTION OF GEO-TEXTILES IN THE COUNTRY.

DEVELOPMENT OF STANDARDS
GEO-SYNTHETICS IN INDIA
ON
4
COMPANY STANDARDS
 IN INDIA VARIOUS STANDARDS ON GEO-SYNTHETICS WERE
EARLIER ATTEMPTED AND PREPARED BY THE USER
DEPARTMENTS TO A LIMITED EXTENT WHICH NORMALLY
COVERED ONLY SPECIFIC REQUIREMENTS PERTAINING TO
THEIR USE.
– FOR EXAMPLE, THE MINISTRY OF ROAD TRANSPORT AND
HIGHWAYS (MRT&H) AND INDIAN ROADS CONGRESS (IRC) HAVE
EVOLVED THE STANDARDS RELATED TO USE OF GEOSYNTHETICS FOR ROAD, ROAD PAVEMENT , BRIDGE WORKS
ETC.
– SIMILARLY RDSO HAS EVOLVED STANDARDS RELATED TO USE
OF GEO-SYNTHETICS FOR RAIL BED STABILIZATION.

N ATIONAL STANDARDIZATION
6
A SYSTEMATIC APPROACH FOR STANDARDIZATION OF GEO-SYNTHETICS AT
NATIONAL LEVEL WAS FIRST ADOPTED BY BIS IN LATE 1980S THROUGH A
NETWORK OF TWO TECHNICAL COMMITTEES,
 GEO-TEXTILES AND INDUSTRIAL FABRICS SECTIONAL COMMITTEE, TX 30
AND

GEO-SYNTHETICS SECTIONAL COMMITTEE, WRD 25.
TX 30 IS LOOKING AFTER STANDARDIZATION WORK RELATED TO TESTING
AND SPECIFICATION REQUIREMENTS FOR GEO-TEXTILES MADE OF
POLYESTER, POLYPROPYLENE, JUTE, COIR AND OTHER FIBRES HAVING
WOVEN/NON-WOVEN/KNITTED STRUCTURE WHILE
WRD 25 MAINLY COVERS GEO-MEMBRANES/GEO-GRIDS/GEO-COMPOSITES
AND ALLIED PRODUCTS (NATURAL AND POLYMERIC) FOR RIVER VALLEY
AND OTHER CIVIL ENGINEERING RELATED APPLICATIONS.
OF LATE WRD 25 HAS BEEN MERGED WITH TX 30
7
 A PROPERLY DESIGNED GEO-SYNTHETIC MATERIAL
IS BELIEVED TO PERFORM THE FOLLOWING
FUNCTIONS SEPARATELY OR IN CONJUNCTION, IN
DIFFERENT APPLICATION AREAS:
–
–
–
–
–
SEPARATION
FILTRATION AND DRAINAGE
INITIAL REINFORCEMENT
CONTROL OF SURFACE SOIL DETACHMENT
VEGETATION OR BIO-TECHNICAL SUPPORT

NEED FOR TESTING
 PRODUCTS ARE TESTED FOR THE FOLLOWING
REASONS:
* QUALITY ASSURANCE AND CONTROL
* SETTING AND MAINTAINING PERFORMANCE
STANDARDS
* INVESTIGATION OF COMPLAINTS
* PRODUCT DEVELOPMENTS AND RESEARCH

11
 GEO-TEXTILES HAVE SPECIFIC CONSTRUCTIONS
AND WORK IN SPECIFIC SOIL CONDITIONS AND END
USES, THE TEST METHODS USED FOR ORDINARY
TEXTILES ARE NOT APPLICABLE TO THEM.
 THE DEGREE OF BENEFITS OFFERED BY GEOTEXTILE MATERIALS TO SOIL FABRIC AGGREGATE
SYSTEM DEPENDS TO A LARGE EXTENT ON THE
PROPERTIES OF THE SOIL AS WELL AS THE FABRIC
USED
 KEEPING THIS IN VIEW, BIS HAS PUBLISHED INDIAN
STANDARDS ON GEO-SYNTHETICS
12

IS 13321(PT 1): 1992 GLOSSARY OF TERMS FOR GEOSYNTHETICS, PART I TERMS USED IN MATERIALS AND
PROPERTIES
THIS STANDARD IS COMPILATION OF THE TERMS RELATING
TO MATERIAL AND PROPERTIES, LIKE ABSORPTION,
APPARENT OPENING SIZE, BIO-DEGRADABILITY, BONDING,
BREAKING LOAD, TOUGHNESS, CHEMICALLY BONDED
NON-WOVEN FABRIC, CLOGGING, COATED FABRICS,


IS 13326(PT 1): 1992 - METHOD OF TEST FOR THE
EVALUATION OF INTERFACE FRICTION BETWEEN GEOSYNTHETICS AND SOIL PART I MODIFIED DIRECT SHEAR
TECHNIQUE
THIS STANDARD PROVIDES DETAILS ON TEST METHODS
FOR DETERMINATION OF COEFFICIENT OF INTERFACE
FRICTION BETWEEN A GIVEN SOIL (INCLUDING AGGREGATE
AND BALLAST) AND A GEO-SYNTHETIC USED FOR
REINFORCEMENT PURPOSES. THIS METHOD IS ALSO
APPLICABLE FOR ASSESSING THE FRICTION BETWEEN A
GEO-MEMBRANE AND THE NATURAL OR COMPACTED SOIL
IN ORDER TO ANALYZE THE STABILITY OF THE
CANAL/RESERVOIR LINING.
14

IS 14986:2001 GUIDELINES FOR APPLICATION OF
JUTE GEO-TEXTILE FOR RAIN WATER EROSION
CONTROL IN ROAD AND RAILWAY EMBANKMENT
AND HILL SLOPES
THIS STANDARD HAS BEEN PREPARED BASED ON
THE DATA PROVIDED BY THE INDIGENOUS
MANUFACTURERS AND TAKING INTO
CONSIDERATION THE PRACTICE PREVALENT IN
INDIA. THE SPECIFIC REQUIREMENTS,
SELECTION, INSTALLATION METHOD,
MONITORING AND REQUIREMENT OF PACKING
HAVE BEEN COVERED IN THIS STANDARD
15

IS 13162(PT 2):1991 GEO-TEXTILES - METHODS OF
TEST PART 2: DETERMINATION OF RESISTANCE
TO EXPOSURE OF ULTRA-VIOLET LIGHT AND
WATER (XENON ARC TYPE)
THIS STANDARD PRESCRIBES A METHOD FOR
THE DETERMINATION OF RESISTANCE OF GEOTEXTILES TO THE EXPOSURE OF ULTRAVIOLET
LIGHT AND WATER. THE LIGHT AND WATER
EXPOSURE APPARATUS EMPLOYS A XENON-ARC
LIGHT SOURCE.
16
 Geo-textiles are manufactured using a variety of processes
and formulations of polymers and each geo- textile varies
in its sensitivity to ultraviolet radiation. Ultraviolet radiation
from the sun varies with duration of exposure, angle of
inclination of the sun, atmospheric conditions, topography,
and geography. The Xenon-arc test cannot simulate all
these variables, so it is not likely that Xenon-arc test
results will relate directly to sunlight exposure test results
for a specific fabric at a given site.
 The method prescribed is suitable for comparative
evaluation of geotextiles and is not recommended for
acceptance testing of commercial shipments since
information on inter-laboratory precision is incomplete.
17

IS 13162 (PT 3): 1992 GEO-TEXTILES - METHODS OF TEST
PART 3: DETERMINATION OF THICKNESS AT SPECIFIED
PRESSURE
THIS STANDARD PRESCRIBES TWO METHODS FOR
DETERMINATION OF THE THICKNESS OF GEO-TEXTILES AT
SPECIFIED PRESSURES AND DEFINES AT WHICH
PRESSURE THE NOMINAL THICKNESS IS DETERMINED.
METHOD A ( LOADING EACH SET OF SPECIMENS ) SHALL
BE USED WHEN USING AN APPARATUS THE
CONSTRUCTION OF WHICH CAUSES A HIGH DEGREE OF
TIME AND/OR LABOUR WHEN CHANGING THE PRESSURE,
OTHERWISE METHOD B (INCREMENTAL LOADING OF
INDIVIDUAL SPECIMENS ) SHALL BE USED. THE METHOD
IS APPLICABLE TO ALL TYPES OF GEO-TEXTILES.
18
 Since the geotextiles are compressible, the
thickness measure will depend upon the
pressure applied. For this reason it may be
desirable to measure thickness at a series
of pressures and to study the general
relationship between thickness and
pressure.
19

IS 13162 (PT 4): 1992 GEO-TEXTILES - METHODS OF TEST
PART 4: DETERMINATION OF PUNCTURE RESISTANCE BY
FALLING CONE METHOD
Geotextiles used as separator and filter in earth
constructions are normally subjected to dynamic
impact. During the installation process, crushed rock or
boulders are dropped onto a fabric
supported by weak, water-saturated soil which may
penetrate and thus damage the geotextile. It is,
therefore, desirable that the geotextiles should resist
the sudden impact and penetration of
such particles.
20
THIS STANDARD PRESCRIBES A
METHOD FOR DETERMINATION OF THE
SIZE OF THE HOLE MADE BY
DROPPING A STANDARD BRASS CONE
ONTO A GEO-TEXTILE, SUPPORTED BY
WATER, AND TO PROVIDE AN
INDICATION OF THE ABILITY OF THAT
FABRIC TO RESIST A SUDDEN IMPACT.
21

IS 13162 (PT 5): 1991 GEO-TEXTILES - METHODS OF TEST PART 5:
DETERMINATION OF TENSILE PROPERTIES USING A WIDE WIDTH
STRIP
THIS STANDARD PRESCRIBES AN INDEX TEST METHOD FOR
DETERMINATION OF THE TENSILE PROPERTIES OF GEO-TEXTILES
AND RELATED PRODUCTS USING A WIDE WIDTH STRIP. THE METHOD
IS APPLICABLE TO MOST GEO-TEXTILES INCLUDING WOVEN FABRICS,
NON-WOVENS, LAYERED FABRICS, KNITTED FABRICS AND FELTS. THE
METHOD IS APPLICABLE TO GEO-GRIDS BUT THE SPECIMEN
DIMENSIONS MAY NEED TO BE ALTERED. THIS METHOD COVERS THE
MEASUREMENT OF LOAD ELONGATION CHARACTERISTICS AND
INCLUDES PROCEDURES FOR CALCULATION OF SECANT STIFFNESS,
MAXIMUM-LOAD PER UNIT WIDTH, STRAIN AT MAXIMUM LOAD AND
EQUIVALENT STRAIN AT MAXIMUM LOAD. PROCEDURES FOR
MEASURING THE TENSILE PROPERTIES OF BOTH CONDITIONED AND
WET SPECIMENS ARE INCLUDED. THE MEASURING DEVICE CAN BE
EITHER MECHANICAL, OPTICAL OR INFRA-RED.
22
The basic distinction between this method and
other methods for measuring tensile properties of
fabrics, is the width of the specimen. This width by
contrast is greater than the length of the
specimen. Some geotextiles have a tendency to
contract ( neck down ) under load in the gauge
length area. The width of the specimen specified in
this method reduces the contraction effect of those
fabrics and provides a closer relationship to
expected fabric behaviour in the field and a
standard comparision of geotextiles.
23
 IS 14293: 1995 GEO-TEXTILES - METHODS OF TEST FOR
TRAPEZOID TEARING STRENGTH
THIS TEST METHOD IS USED TO MEASURE THE TEARING
STRENGTH OF WOVEN OR NON-WOVEN GEO-TEXTILES BY THE
TRAPEZOID METHOD.
THIS TEST METHOD MAY BE USED WITH CONSTANT RATE OFTRAVERSE (CRT) OR CONSTANT-RATE-OF-EXTENSION (CRE)
TYPE TENSION MACHINES. HOWEVER, THERE MAY BE NO
OVERALL CORRELATION BETWEEN THE RESULTS OBTAINED
WITH THE CRT MACHINE AND THE CRE MACHINE.
CONSEQUENTLY, THESE TWO TENSION TESTERS CANNOT BE
USED INTERCHANGEABLY. IN CASE OF CONTROVERSY, THE
CRE MACHINE SHALL PREVAIL.
24

IS 14294: 1995 GEO-TEXTILES - METHOD
FOR DETERMINATION OF APPARENT
OPENING SIZE BY DRY SIEVING
TECHNIQUES
THIS INDIAN STANDARD SPECIFIES METHOD
TO DETERMINE APPARENT OPENING SIZE
(AOS) BY DRY SIEVING TECHNIQUE. THIS

 IS 14706:1999 GEO-TEXTILES - SAMPLING AND
PREPARATION OF TEST SPECIMEN
THIS INDIAN STANDARD PROVIDES GENERAL
PRINCIPLES FOR SAMPLING OF GEOTEXTILES AND PREPARATION OF TEST
SPECIMENS FROM THE SAMPLES. THE
PRINCIPLES ARE APPLICABLE TO ALL GEOTEXTILES SUPPLIED IN ROLLS.
27
 IS 14714:1999 GEO-TEXTILES DETERMINATION OF ABRASION RESISTANCE
THIS TEST METHOD COVERS
DETERMINATION OF RESISTANCE OF GEOTEXTILES TO ABRASION USING AN ABRASION
TESTER. THE TEST METHOD IS APPLICABLE
TO ALL GEO-TEXTILES AND IS NOT SUITABLE
FOR GEO-SYNTHETICS.
28
 IS 14715:2000 GEO-TEXTILES - GEO-JUTE FABRICS
(JUTE GEO-TEXTILES) WOVEN - SPECIFICATION
THE STANDARD PRESCRIBES CONSTRUCTIONAL
DETAILS AND OTHER DETAILS OF WOVEN JUTE GEOTEXTILES. WOVEN JUTE GEO-TEXTILES ARE USED
FOR STABILIZATION OF SOIL THROUGH VEGETATION
AGAINST EROSION OF LANDSCAPE AND SOIL
SLOPES AS WELL AS PROTECTION OF RIVER BANK
AGAINST EROSION AND SIMILAR APPLICATIONS
INVOLVING SEPARATION AND FILTRATION. THE
STANDARD IS BASED ON WORK DONE BY INDIAN
JUTE INDUSTRY’S RESEARCH ASSOCIATION,
CALCUTTA IN THIS FIELD.
29
 IS 14716:1999 GEO-TEXTILES DETERMINATION OF MASS PER UNIT AREA
THIS STANDARD SPECIFIES A METHOD FOR
THE DETERMINATION OF THE MASS PER UNIT
AREA OF GEO-TEXTILES FOR IDENTIFICATION
PURPOSES AND FOR USE IN TECHNICAL DATA
SHEETS.
30
 IS 14739:1999 GEO-TEXTILES - METHOD
FOR DETERMINATION OF CREEP
THIS STANDARD DESCRIBES A METHOD
FOR DETERMINING THE LOAD-STRAINTIME RELATIONSHIP OF GEO-TEXTILES
AT A GIVEN TEMPERATURE FROM A
SERIES OF CONSTANT LOAD TESTS.
31

IS 15060:2001 GEO-TEXTILES - TENSILE TEST FOR JOINTS/SEAMS BY WIDE
WIDTH METHOD
THIS STANDARD SPECIFIES AN INDEX TEST METHOD FOR DETERMINATION OF
THE TENSILE PROPERTIES OF JOINTS AND SEAMS IN GEO-TEXTILES AND
RELATED PRODUCTS, USING A WIDE-WIDTH STRIP. THE METHOD IS
APPLICABLE TO MOST GEO-TEXTILES AND GEO-TEXTILE-RELATED PRODUCTS.
IT IS ALSO APPLICABLE TO GEO-GRIDS, BUT THE SPECIMEN DIMENSIONS MAY
NEED TO BE ALTERED. PROCEDURES FOR MEASURING THE TENSILE
PROPERTIES OF BOTH CONDITIONED AND WET SPECIMENS ARE INCLUDED.
SOME MODIFICATION OF TECHNIQUES MAY BE NECESSARY FOR PARTICULAR
GEO-TEXTILES, E.G. STRONG GEO-TEXTILES, MESHES OR GEO-TEXTILES
MADE FROM GLASS FIBRE, TO PREVENT THEM FROM SLIPPING IN THE JAWS
OR BEING DAMAGED AS A RESULT OF BEING GRIPPED IN THE JAWS. THE
BASIC TEST FOR JOINTS OR SEAMS IN ALL KINDS OF GEO-TEXTILES OR
RELATED PRODUCTS USES TEST SPECIMENS OF 200 MM WIDTH, WITH THE
PROVISION FOR THE SEAM OR JOINT TO EXTEND FOR 25 MM ON EACH SIDE IN
ORDER TO PROVIDE JOINT OR SEAM STABILITY DURING THE TEST.
