1. What are Geotextiles?
Geotextiles are porous, woven, or non-woven fabrics manufactured from synthetic materials such as PET or PP. These are especially developed to be employed in projects involving civil engineering and the environment. They provide a separation, filtration, drainage function, reinforcing, and protection whenever applied during constructions. Geotextiles represent light, flexible, inexpensive solutions as compared with more traditional construction materials. They will contribute considerably toward increasing stability and durability in engineering structures.
Simplified, geotextiles are special textiles for solving various problems of soils in certain aspects of building and environmental engineering. They allow water to pass through while maintaining the soil particles; thus, they are highly effective in erosion control and drainage systems.
2. Types of Geotextiles and Their Applications
A number of types of geotextiles exist, all of which have different properties and uses. The following are those in common use and their major applications:
PET Filament Nonwoven Geotextiles
These geotextiles have been produced from continuous polyester filaments, which have extremely high tensile strength with good resistance against chemical degradation.
Applications: Filtration, drainage, and slope protection are perfect in road construction, landfills, and tunnels.
PET Staple Fiber Needle-punched Nonwoven Geotextiles
Made from short polyester fibers carefully needle-punched to enhance flexibility and permeability to water.
Applications: Geotextiles are widely in erosion control, landscaping, and also as protection layers for geomembranes for landfills and reservoirs.
PP Staple Fiber Needle-punched Nonwoven Geotextiles
These are made of polypropylene fibers, characterized by small weight and resistance to biological and chemical destruction.
Applications: Drainage, separation, and soil stabilization, serving vital roles in agriculture, canals, and bridges.
PP Woven Geotextiles
They are made of woven polypropylene fibers which are highly resistant to tensile loading at minimum percentage elongation.
Applications: Widely used for reinforcement and separation in the building of roads, retaining walls, and artificial lakes.

2). Dams and Reservoirs
Recommended Geotextile: PET staple fiber needle-punched nonwoven geotextiles.
Application: They act as a protective barrier, preventing soil erosion while allowing water retention. In addition, geotextiles stabilize the soil that is underneath the structure.
3). Canals and Waterways
Recommended Geotextile: PP Staple Fiber Needle Punched Nonwoven Geotextiles.
Application: Lay geotextiles along canal beds and slopes, preventing soil erosion while maintaining the efficiency of water flow.
4). Tunnels and Bridges
Recommended Geotextile: PET filament nonwoven geotextiles.
Usage: As drainage layer, relieve water at the tunnel wall or from the bases of bridges, and relieve hydrostatic pressure.
5). Artificial Lakes and Ponds
Recommended Geotextile: PP woven geotextiles.
Application: This will line the bottom to prevent punctures thus giving structural reinforcement to the lakebed.
5. At What Occasions Do You Actually Need Geotextiles for Your Projects?
Geotextiles are crucial to your project when:
Soil Instability Problem: This type of textile plays a very vital role in making the weak soils stable and avoiding settlement in road building, bridges, and embankments.
Erosion Control Shall be Applied: When the project comes to slopes, waterways, or coasts, erosion control is given by geotextiles.
Drainage is Critical: Geotextiles allow for the flow of water and prevent soil from clogging; therefore, they are vital in drainage systems.
Separation is Needed: Geotextiles prevent the mixing of the soil layers when one is developing the roads or retaining walls and hence maintains the structural integrity.
It is Cost-effective: Geotextiles are a cheap way of approaching such conventional construction materials while maintaining longevity.
6. Creative Ideas for Geotextile Applications
Besides the general uses of geotextiles, some specific uses of geotextiles are given below:
Green Roofs: Facilitate improved drainage, retention of soil, and urban sustainability of green roofs using lightweight geotextiles.
Vertical Gardens: Geotextiles used for vertical gardens help in enhancing their water-retention and filtration capability.
Rainwater Harvesting: Rainwater harvesting pits can be lined with geotextiles to enhance filtration and reduce soil erosion.
Temporary Roads: Woven geotextiles are used for fast-track temporary road stabilization during construction or disaster recovery efforts.
Flood Control: Geotextiles laid with sandbags for temporary barriers to floods.

Geotextiles FAQs
1. What is geotextile and what are its core functions?
Geotextile is a kind of permeable fabric made of synthetic materials (such as polyester PET or polypropylene PP) . It is widely applied in the anti-seepage projects of civil engineering and environmental protection(i.e. landfills), agriculture or aquaculture water treatment, etc.
There are some essential functions that geotextiles possess as follows:
- Filtration: Allow any water to flow through the geotextile fluently while effectively prevent soil particles from flowing away.
- Reinforcement: Improve the stability of soil base and relieve the overloading pressure.
- Isolation: Prevent soil layers of different particle sizes from interfering with each other.
- Drainage: Decrease the water pressure by promptly draining excessive water.
- Protection: Protects geomembranes or other structures from mechanical damage.
2. What Are the Main Types of Geotextiles and Their Applications?
PET Filament Nonwoven Geotextiles: They are made of durable continuous filaments in premium quality. These geotextiles suit projects that need filtration or drainage, such as road construction, landfills, tunnels, etc.
PET Staple Fiber Needle-punched Nonwoven Geotextiles: Made of staple fiber nonwoven cloth, they are suitable for the protection of slope, landscaping, and geomembranes for anti-seepage.

4. Can Geotextiles be Used for Prevent Soil Erosion? How Does it Work?
Yes, geotextiles are effective in preventing soil erosion, especially in slope, riverbank, and dam protection.
Working principle:
Geotextiles are laid on slopes or open soil to create some sort of protection that prevents direct erosion by wind and rain.
Geotextiles prevent erosion damage in riverbanks and dams by stabilizing the soil particles and allowing water to pass through.
In canals, it protects the underlying structure and prevents sediment deposition.
5. What are Attention Points in the Construction of Geotextiles?
Foundation Treatment: The ground should be cleaned up. Make sure there is no sharp stone or debris on the construction surface before laying geotextiles to avoid piercing the puncture of geotextiles.
Overlap Length: Lay down the geotextiles and reserve the overlap length (usually 15 – 30cm) according to the specific project requirement to ensure the whole stability.
Fixing Method: Use nails, sandbags, or other fixing measures to prevent the blowing away of geotextiles by wind or water.
Protective Measures: After laying, contact with heavy machinery should be minimized to avoid damage to the geotextiles as much as possible.
Quality Check: The geotextiles should not be torn, wrinkled, or displaced and on-site inspections should be done after the construction.
