  Geotextile-Geonet Composites

• The purpose of this type of composite is that as soon as a geotextile is used on one or both sides of a geonet, the basic function that we are looking for, from the same, like separation and filtration functions gets satisfied, on the same time the drainage function is also vastly improved.
• This type of composites is very often used in
• Intercepting and conveying leach ate in landfill lining and
• Also it helps in conducting vapor or water below pond lining.
• They are very good in draining water in a capillary zone where frozen dew or vapor drainage or salt migration is very  doubtful.
• The mechanism of drainage is like the water will enters through the geotextile and then flows horizontally within the geonet to a suitable exit.

• Geotextile-Geomembrane Composites

• For special purpose geomembrane can be laminated by geotextiles.
• The geotextiles offer better resistance to puncture, tear propagation, and friction related to descending, as well as provide tensile strength.
• Sometimes the geotextiles are of the nonwoven, needle-punched variety and are  comparatively weighty.
• In that case above type of geotextile element perform as drainage media.

• Geomembrane-Geogrid Composites:

• Some Geomembrane & geogrid are made from similar material for e.g. high density polyethylene, so they can be bonded jointly for composites.
• The main purpose of this composite is that it gives strong barrier with superior strength & resistance abilities.

• Geotextile-Geogrid Composites

• The main end use of this type of composite is:
• Increase tensile reinforcement along with drainage.
• They are also used for interior drainage of low-permeability backfill soils for unbreakable walls and gradient.

• Geotextile-Polymer Core Composites

• This composite is made by extruding process & it is being used as a drainage core. The special function it performs is that it allows very large quantities of liquid to flow within the structure.
• The geotextile is added as a composite for protection of polymer core.
• A range of systems are existing, each focused on an exacting appliance.

• The first is famous as wick drains in the U.S. and vertical drains in Europe. The polymer core with dimension of 100 mm wide by 5 mm thick often used for easily conducting of water. The other component of composite geotextile stand-in as a filter and separator surrounding the core. The surfacing of such wick drains has reduced conventional sand drains as a swift way of strengthening fine-grained waterlogged soils.
• The second type is in the form of drainage sheet. The stiff polymer core being nubbed, columned, dimpled with a geotextile for an excellent drainage on the backfilled side of preserving walls, cellar walls and mall floor.
• The third type contained by this part of drainage geocomposites is the class of manufactured edge drains. These resources, normally 500 mm high by 20 to 30 mm wide are located next to a highway roadway, airport roadway, for sideways drainage. The systems are very rapid in their installation and extremely economic.

Advantages:

• Noticeably lengthens the stability of asphalt layers in road surfaces.
• Significantly reduces the occurrence of cracks.
• Reduces the formation of ruts in areas of high traffic loading.
• The construction of the geo-composite guarantees optimum adhesion with the asphalt layers.
• White color guarantees the transparency of its penetration into the asphalt mixture.
• Maintain material resistance up to 220° C.
• Easy installation without the necessity of fixing to surface by nails.
• High resistance to damage during installation.

Main applications:

• Constructing new roads.
• Repairing damaged sections of asphalt surfaces of roads, motorways, parking, airport surfaces and access ways.
• Expanding thoroughfares and road lanes.
• Asphalt reinforcing at locations subject to intensive vehicle braking or accelerating, important junctions, bus stops etc.
