GEOMEMBRANES:-These are used primarily for liningsand covers of liquid or solid storage facilities .These are essentially
impermeable material in the form of manufactured sheet which may
be synthetic. Thus the primary function is always as a liquid or gasbarrier .The range of application is very high. These are act as a
barrier for flow of water or any hazardous liquid. The simplest
example is canal lining
Non-Woven Compound Geo membrane

GEOGRIDS
These can be in the form of manufactured sheet, consisting of a
regular network of integrally connected elements, which may belinked by extrusion , bonding.
Have high tensile strength and dimensional property at very low
elongation.
Coated polyester geogrids widely used in soil stabilization and
Geotechnical reinforcement of retaining walls and embankment
applications.
Biaxial geogrids are used as separator in between sub grade and
aggregate

Unidirectional Geogrid:-possessing high tensile strength in one
direction (that is longitudinal and transversal) than in the other
direction.
Bidirectional Geogrid:- possessing similar tensile strength inboth direction that is longitudinal and transversal.
Extruded Geogrid:-produced by stretching uniaxially or
biaxially an extruded integral structure .
Bonded Geogrid:- produce by bonding stretching right angles ,two or more sets of strands filaments and yarns.
Woven Geogrid:- produce by interlacing at right angle, two or
more sets of strands filaments and yarns.
ACCORDING TO PHYSICAL STRUCTURE GEOGRIDS
CAN BE CLASSIFIED INTO FOLLOWING
CATEGORIES .

GEONETS
These are usually formed by continues extrusion of parallel sets ofpolymeric ribs at acute angels to each other. These net like configurationare mostly useful in drainage application .
These are look like geogrid but have substantially lower strength
These are used for drainage applications because these are provide spacebetween two non woven textiles to minimize clogging and any possibleleakage from either of the membranes as a geocomposites
.

GEOCOMPOSITES
When geogrid/Geomembranes are combined with woven or non
woven Geotextile for specific application like drainage, erosioncontrol, bank embankment, etc. then they are designed as
GeoComposites.
A typical example is bentonite geocomposite.
It consists bentonite filled pores when this geotextile come incontact with water the bentonite causes the pores to swell thereby
forming water tight sheets.
Glass fibers are knitted on to the non woven geotextiles to enable
better use in highway applications.
Geo composite is made by laminating
a nonwoven geo textile

GEOCELL
It is a polymeric cellular structure consisting of a regular open
network of connected stripes linked by extrusion , adhesion or by
other methods.
These are used as embankment geo textile which have high tensile
strength to prevent bank from the cracks .The rigidity of these
textile ensure the even distribution of force exhibited by water.
The Geocell is soil infill.
protection of outer cell by topsoil.

Biomat and Bionet
These are permeable , natural and therefore biodegradablepolymeric material in the form of the manufactured sheet. Biomat
consists of fiber such as jute , coir, sisal, straw, are kept together
by one or two layers of synthetic or natural meshes and bionet
consist of a regular network of knotted or interlaced yarns whose
openings are lager than the constituents.
Jute are used for moisture holding capacity of soil these are
degrade into the soil and reduce the velocity of flow of water and
hold the fertile soil at place.
