A well-liked product in the engineering community is geosynthetic. This product is often used to important structural components for engineering applications. It is derived from a polymeric substance.

The prefix “geo” indicates that this product is heavily associated with certain geological components, such as earth, rocks, and soil.
A geosynthetic product can be used for a variety of purposes, such as surface erosion control, containment, drainage, reinforcement, barrier, and any other purpose that a geosynthetic material is meant to have.
This material is mostly used in the fields of civil engineering, transportation, geology, marine engineering, hydraulics, roads, railroads, retaining walls, canals, and other constructions where it is necessary for specific engineering goals.
However, the usage of geosynthetic materials might take precedence over the previously specified regions with the development of additional related goods.
Various Geosynthetic Types
• Geogrids
• Geotextiles
• Geonets
• Geomembranes
• Geosynthetic clay liners
• Geopipe
• Geofoam
• Geocomposites
1. Geogrids
These are polymers that, for instance, are formed into a very wide, grid-like shape with enormous gaps between each rib in the machine and cross-machine orientations.
These geosynthetic materials are produced in a variety of ways:
elongated in one or both directions to improve the physical characteristics
produced with the use of the greatest techniques and weaving or knitting gear.
It is created by combining straps and rods.
2. Geonets
The process of creating this material involves continuously extruding parallel groups of polymeric ribs that are 90 degrees apart.
When the ribs are open, they create a huge, net-like opening. They are primarily designed to be used in drainage applications where liquids need to be transported.
3. Geomembranes
This extremely thin geosynthetic material is made up of impermeable polymeric layers that are primarily used to line and cover liquid-storage structures like landfills, canals, and other containment facilities.
4. Geosynthetic Clay Liners
GCLs, or geosynthetic clay liners, are essentially polymer and natural oil materials compared.
These materials are bentonite clay folds that are manufactured in factories and either wrapped around two geotextiles or combined with a geomembrane.
GLCs have applications in transportation, geotechnical engineering, hydraulics, and the environment as well as confinement.
5. Geopipes
Because of its widespread usage in geotechnical, environmental, and hydraulic fields—including private development engineering—geopipe is recognized as a kind of geosynthetics.
6. Geofoam
The final outcome of this polymeric expansion process is a foam composed of many closed cells that are compressed with gas.
The unexpanded polymeric substance makes up the skeleton of the cell walls.
7. Geocomposites
The combination of geotextiles, geonets, geogrids, and geomembranes is known as geocomposites.
The aforementioned components can also be combined with any other synthetic material, such as steel wires or distorted plastic sheets.
This material serves a variety of purposes, including drainage, separation, and strengthening.
8. Geotextiles
Geotextiles are textiles in the conventional sense, as the name suggests.
However, rather of being composed of natural fibers like wool, cotton, or silk, this material is composed of synthetic fibers. They have a brief lifespan after being highly biodegradable.
Installing geotextiles is a simple process, albeit it varies according on the application.
Geotubes and geotextiles are connected. Projects of all sizes involving the dewatering of sludge employ geotubes.
Similar to the installation of geotextile, installing geotube doesn’t have to be difficult; nevertheless, this also depends on the location in which it will be used.
The advantages of Geosynthetic
1. Filtration of Water
The inappropriate handling of water on sites leads to a number of issues, one of which being erosion.
Since irreversible depressions are frequently the result of erosion, a geosynthetic material—the Geocomposite clay liner, specifically—can be utilized to stop this from happening by putting it beneath the hydraulic system.
2. Construction of Drains
If runoff is not properly controlled or diverted, erosion may result. A rise in the water table indicates ineffective water retention on both sides of a structure, such as an embankment, and this leads to pore pressure.
Pore pressure must be stopped by providing a 50% reinforcement. In this sense, a geocomposite liner is quite advantageous.
3. Control of Soil Erosion
One of the greatest advantages of geosynthetic materials is found here. Mattresses, geotextiles, and gabions are useful in stopping erosion.
Additionally, the geotextile filter—which also includes geotextile reinforcement—means that even during times of intense rainfall, the soil will be robust and stable.
Because of their many advantages and practicality, geosynthetic materials are frequently used in building projects.
This material has characteristics that enable it to carry out a number of important tasks in buildings such as foundations, canals, and retaining walls.
