Q:What is the difference between woven and non-woven geotextiles?: Woven geotextiles are made by interlacing yarns or fibers together, creating a strong and durable fabric. They have a high tensile strength and are commonly used for applications that require high load-bearing capacity, such as stabilizing soil or preventing erosion. Non-woven geotextiles, on the other hand, are made by bonding fibers together using heat, chemicals, or mechanical processes. They are generally less strong and more flexible than woven geotextiles. Non-woven geotextiles are often used for filtration, separation, or drainage purposes, where their permeability and ability to retain fine particles are important factors.

Q:Where is the non-woven geotextile in the tunnel?: The nonwoven geotextile is used to isolate the dome between the concrete and the waterproof layer in the tunnel.

Q:I'm looking for the fabric that goes between gravel and the ground (for a gravel driveway).: you can get this at wicks do it all (now focus) or any good building merchants

Q:Can geotextiles be used in stormwater management systems?: Yes, geotextiles can be used in stormwater management systems. Geotextiles are often used to enhance filtration and separation in stormwater management applications, helping to control erosion and retain sediment within the system. They can be used in various components of stormwater systems such as sediment basins, retention ponds, and biofiltration systems to improve their effectiveness and longevity.

Q:How do geotextiles affect visual aesthetics?: Geotextiles, being a synthetic fabric, can often blend seamlessly with the surrounding environment due to their neutral color and texture. This can enhance the visual aesthetics of an area by creating a more cohesive and harmonious appearance. Additionally, geotextiles can be used to stabilize soil and prevent erosion, leading to a more visually pleasing and well-maintained landscape.

Q:What are the key factors affecting the durability of geotextiles?: The key factors affecting the durability of geotextiles include exposure to environmental conditions such as ultraviolet (UV) radiation, temperature variations, moisture, and chemical exposure. The quality of the geotextile material and its resistance to degradation, abrasion, and puncture also play a crucial role in determining its durability. Proper installation, maintenance, and adherence to design specifications are additional factors that can impact the longevity of geotextiles.

Q:Are geotextiles resistant to hydrocarbons?: Yes, geotextiles are generally resistant to hydrocarbons.

Q:How do geotextiles help with stabilization of railway tracks?: Geotextiles play a crucial role in stabilizing railway tracks by providing reinforcement and separation between different layers of the track structure. They prevent the mixing of materials, such as subgrade soil and ballast, while also reducing the lateral movement of the ballast. Geotextiles enhance the overall stability and load-bearing capacity of the track, reducing maintenance needs and extending its lifespan.

Q:How do geotextiles contribute to soil improvement in soft ground areas?: Geotextiles contribute to soil improvement in soft ground areas by providing reinforcement and stabilization. They act as a barrier to prevent the mixing of soil layers, reducing settling and heaving. Geotextiles also enhance drainage and filtration, allowing water to pass through while retaining soil particles. This helps in preventing erosion, maintaining the integrity of the soil, and improving its overall stability.

Q:Are geotextiles resistant to earthquakes?: No, geotextiles are not inherently resistant to earthquakes. While geotextiles can provide benefits in terms of soil stabilization and erosion control, they do not have the ability to withstand seismic activity on their own. Additional engineering measures and materials are required to ensure structures are earthquake resistant.
