What are Geotextile Fabric?
Geotextiles are permeable materials that, when combined with soil, can separate, filter, reinforce, protect, or drain.
Geotextile fabrics, which are often comprised of polypropylene or polyester, are classified into three types: woven (similar to mail bag sacking), needle punched (similar to felt), and heat bonded (resembling ironed felt).
Geotextile composites have been produced, as have products such as geogrids and meshes. Geotextiles are long-lasting and can lessen a fall if someone falls.
These materials are collectively known as geosynthetics, and each configuration—geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others—can provide advantages in geotechnical and environmental engineering design.
Geotextiles Fabric Uses
Geotextiles and related products have several uses, including highways, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering, and building site silt barriers or geotube.
Geotextiles are typically installed at the tension surface to reinforce the soil. Geotextiles are also utilized to protect upland coastal property from storm surge, wave action, and flooding by armoring sand dunes.
Within the dune system, a massive sand-filled container (SFC) stops storm erosion from progressing beyond the SFC. Using a sloped unit instead of a single tube eliminates scour.
The benefit of sloped, stepped designs in decreasing storm-related beach erosion damage is mentioned in erosion control guidelines.
For upland property protection, geotextile sand-filled units offer a “soft” armoring solution. Geotextiles are utilized as matting in stream channels and swales to stabilize flow.
Geotextiles can strengthen soil at a lesser cost than traditional soil nailing. Geotextiles also allow for planting on steep slopes, further stabilizing the slope.
Geotextiles were employed to protect the Laetoli fossil hominid footprints in Tanzania from erosion, rain, and tree roots.
Geotextile textiles, in conjunction with steel wire fencing, can be used to contain explosive material during building demolition.
Because of their high mechanical strength, coir (coconut fiber) geotextiles are used for erosion control, slope stabilization, and bioengineering.
Coir geotextiles have a life expectancy of 3 to 5 years, depending on the fabric weight. The product degrades to humus, which enriches the soil.
Geotextiles can be easily transported and moved from one place to another. Geotextiles are also used as containers in waste management, which help to store waste items until they are removed from the construction site.
Functions of Geotextiles Fabric
Geotextiles are a type of fabric that is used for a variety of purposes.
1. Reinforces and Protect the Soil
These flexible woven materials are often used to reinforce and protect the soil against erosion, which helps to reduce the risk of landslides.
2. Removal of Silt and Rock
During construction projects, geotextiles are used to transport and collect the material that is removed by excavators. The soil can also be removed by passing a tractor with an auger through the fabric into the soil while it is being loosened.
3. Filter Soil & Water
Geotextiles are often used in stream channels and swales to filter sediment and water. Geotextiles are also used to control water flow and manage sediment by limiting the amount that flows downhill.
4. Sealing
Geotextiles are often used as a sealing material when installing tile drains. They are also key in drying and leveling wet soil, which is important for large construction projects such as building sports stadiums, soccer stadiums, and shopping malls
5. Containers
The geotextile containers and can also be used to hold material in place or within the container for temporary storage. The use of geotextile containers is becoming very popular in the construction and waste management industries, especially when they are loaded with waste materials.
Geotextiles are a highly versatile product that is used on just about every large-scale construction project.
Geotextile Fabric Advantages and Disadvantages
Geotextile Advantages
1. Geotextiles are Lightweight
These products are lightweight and can be easily transported. In the topography, geotextiles are used to reinforce and protect the soil against erosion, which helps to reduce the risk of landslides.
The aggregate material is also used in excavating of the soil so that it can be removed by passing a tractor with an auger through the fabric into the soil while it is being loosened.
2. High tear strength
The geotextiles are high tear strength and these products are used in the removal of sediment as well. Geotextiles are also used to collect material that is excavated from the construction site.
The soil can also be removed by passing a tractor with an auger through the fabric into the soil while it is being loosened.
3. Multipurpose
Geotextile products are multipurpose and helps to limit the amount that flows downhill. These products can be used in the construction of facilities such as parking lots, sports stadiums, and shopping malls.
Geotextiles are also used for agriculture purposes, such as to control erosion and moisture retention in farm fields.
Geotextile Disadvantages
1. Degradation
The geotextiles degrade when they are exposed to sunlight, rain, wind, snow and other harsh elements. This is the reason why the geotextiles are used to collect and remove the material that is excavated.
2. Piling
Geotextile products cannot be used when you need to pile the materials because they are not strong enough to support heavy structures, machines and equipment.
3. Contamination
If these products are contaminated with soil, debris, or other foreign matter, it can be very difficult to clean them after they have been used in a construction project.
4. Wind resistance
Geotextiles are not able to resist windy conditions and are easily torn by the wind. Geotextiles also cannot survive in wet or muddy conditions; if they do, they become heavy and will not be able to support weight.
5. Installation of geotextile is difficult
Installation of geotextile is key and requires experienced contractors who know how to properly install the products.
Geotextile Properties
1. Geotextiles are durable and light-weight
Geotextiles are made from high-strength polypropylene fibers that have been woven together to create a fabric that is light-weight, durable, flexible and pliable.
The properties of geotextiles make them highly versatile as they can be easily transported and installed in most construction environments.
2. Geotextile fabrics are available
Geotextile fabrics are available in several different forms including geogrid, geomembrane, and geotextile.
All three of these products have very similar properties but differ slightly in their construction and density.
Geogrids are used to support foundations for high-rises and are also used as an erosion control method when they are buried vertically into the ground.
3. Geotextile is multipurpose
Geomembranes are used for various different applications including underground storage tanks, landfill liners, and oil containment ponds.
Another common use for geomembranes is to separate two spaces and prevent the migration of contaminants.
The fibers that are used to create these products are made up of a polymer resin that has been spun into very thin fibers and woven together to create a durable fabric.
Geotextiles can be easily transported and installed, which makes them a very versatile product that is used in many different fields including construction, agriculture, and environmental services.
4. Geotextile is easily stored
Geotextiles are lightweight and can be easily stored in warehouses or other facilities. The fibers that create these products are very small and can also be processed to increase their stiffness which helps to make them strong enough for long-term use.
Types of Geotextile Fabric Materials
There are three types of geotextiles which can be natural and artificial.
Natural fibers include sisal, coir (coconut fiber), casava, jute, hemp, wool, cotton, and henequen. The fabric filters the soil and water and is used to control water flow and manage sediment by limiting the amount that flows downhill.
1. Woven Geotextile Fabric
A woven geotextile fabric has a durable and natural fiber that is used in the construction of subsoil drainage and erosion control products.
The substances found in these products are very strong and can be easily transported from one place to another.
2. Non-woven geotextile
A non-woven geotextile does not have a fiber and the passage of water through its porous structure.
The non-woven geotextile is commonly used to protect plants and help to reduce runoff from construction sites.
3. Knitted Geotextile
Knitted geotextile fabric is made up of very fine, smooth fibers that are woven together by flat needles that create a very dense and flexible material.
This type of fabric is commonly used in the construction of buildings, water containment ponds, and other industries related to agriculture.
Geogrid And Geotextile
Geogrid
A geogrid is made up of woven fibers that are placed in parallel rows and perpendicular to each other, which creates a grid pattern that limits the amount of flow in one direction only.
The geogrids are utilized by the HVAC industry as well as for drainage systems.
Geotextile
A geotextile is made up of woven polypropylene fibers that are treated with a polyurethane resin and have a very smooth surface, which is used in the construction of soil protection products.
The fibers that are placed in the fabric have been treated with a polyurethane resin that holds them together in one solid piece.
Difference between geogrid and geotextile
Geotextiles and geogrids provide comparable and often interchangeable tasks. The identical functions, however, are the result of different reinforcing mechanisms.
The reinforcement provided by geogrid is mostly due to the lateral restraint produced by the interlocking of aggregate and geogrid.
Geotextiles, on the other hand, serve in a variety of ways, including strengthening by contact friction, separation of subgrade soil and base course material, filtration, and drainage.
Geotextile Fabric FAQs
1. Can geotextile be used in horticulture?
Yes. Horticulturalists use geotextiles in soil conditioners, to control soil compaction, and to reduce erosion.
For example, the woven geogrid is commonly used to fill in cracks or lines of holes in the soil … or as a moisture barrier to protect plants from the effects of frost or drought.
2. How do the fibers in geotextile hold up?
The fibers in geotextiles are extremely strong. The polymer resin that is used creates a fiber that is able to support heavy loads and withstand the elements.
Although, many factors go into how these products hold up over time. The most important factor is whether the proper installation procedures were followed during the manufacturing process.
3. Can geotextile be used as litter liners?
Yes. Geotextile can be used as a litter liner because the mesh size is designed to promote fast drainage and to prevent the spread of infectious material.
4. How do biofilters work?
Biofilters use plants and bacteria to break down organic waste which helps to keep the water and land around it clean.
This natural process removes odors, cleans the water, and promotes growth in the area surrounding it.
5. Do geotextile products contain plastic?
The fibers in geotextiles are made from polyethylene and cellulose, which help to create a non-toxic product that can be used efficiently in the environment.
6. Do I need to store my geotextile?
The fibers in geotextiles are very lightweight with a specific gravity of .3-1.3, which means that they have very little density and weigh very little.
They can be easily stored, but keep them in a cool, dry place in a sealed container.
7. Do geotextile products cause health problems?
Geotextiles are non-toxic, non-biodegradable products with no known or present effects on human health.
8. What is Geogrid?
Geogrids are used in conjunction with geotextiles to increase the strength of the overall work piece. The fibers can be used together to provide soil stabilization, erosion control, or water filtration.
9. What types of geotextile Are there?
There are four types of Geotextile: woven, non-woven, knitted and bi-directional tapes.
10. Are geotextiles recyclable?
Yes, geotextiles are recyclable because they are made from polypropylene fibers. Although, as of right now, this process is not used very often due to the high costs associated with disposal and recycling.
12. What are the advantages of geotextile?
Geotextiles have several advantages. They can be used to direct water, control erosion, build up soil, or they can be used for filtration.
13. How far can geotextile be shipped?
The short answer would be that geotextile can ship any distance because it weighs almost nothing and is easily transported by truck or air.
14. What are the disadvantages of Geotextiles?
Geotextiles have several disadvantages. The main disadvantage is that they are non-biodegradable and that they require a significant installation process. They also have an application temperature range, which limits their availability in many areas.
15. What is the difference between geogrid and geotextile?
The two main differences would be weight and application. Geotextile is lighter than geogrid, and geotextile can also be applied in an application that uses water where geogrid cannot be used.
Geogrids can also be used in road construction
Geogrids are made of large woven meshes with a net structure instead of a great number of small fibers. Geotextiles have a mesh structure comprising very small fibers “woven” together.
16. What exactly do you mean by “geosynthetics”?
Geosynthetics are synthetic materials that are used to improve soil conditions. The term is derived from the words geo (earth or soil) and synthetics (man-made).
Geosynthetics are typically made of petrochemical-based polymers (“plastics”) that are biologically inert and will not breakdown in the presence of bacterial or fungal action.
Geosynthetics are synthetic materials that are used to stabilize terrain. They are often polymeric goods that are utilized to tackle civil engineering challenges.
Geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells, and geocomposites are among the eight major product groups.
17. Why should we use geosynthetics?
Geosynthetics are synthetic products used to stabilize terrain. They are generally polymeric products used to solve civil engineering problems.
The polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required. They can also be used in exposed applications.
18. How do geosynthetics work?
What is the process of geosynthetics?
Most geosynthetic materials have a passive role; for example, geosynthetic barriers prevent liquids from passing through; geosynthetic reinforcement provides tensile resistance, but only after an initial strain has occurred; and geo-drains provide a path for water but do not cause it to flow.
