Polypropylene geotextile for Coast Construction

Q: Are geotextiles resistant to acid degradation?: Yes, geotextiles are generally resistant to acid degradation. They are designed to withstand various environmental conditions, including exposure to acid or acidic substances, without significant degradation or damage.

Q: Characteristics of nonwoven geotextiles: Non-woven geotextile has many advantages: 1) air permeability 2) filterability 3) insulation 4) water absorption 5) waterproof 6) stretch 7) not disheveled 8) feel good, soft 9) light 10) Can be restored 11) without the direction of the fabric 12) compared with the textile production of high productivity, production speed 13) low prices, can be mass production and so on. Disadvantages are: 1) Compared with the textile fabric strength and durability is poor; 2) can not be washed as other fabrics; 3) fiber arranged in a certain direction, so easy to split from the right angle and so on. Therefore, the improvement of the production method has been mainly focused on preventing the improvement of the division.

Q: How do geotextiles help with filtration in geosynthetic clay liners?: Geotextiles play a crucial role in enhancing filtration in geosynthetic clay liners (GCLs) by acting as a barrier that prevents fine particles from migrating into the clay layer. The geotextile acts as a filtration medium, allowing water to pass through while retaining the soil particles. This helps to maintain the integrity and effectiveness of the GCL by preventing clogging and maintaining the desired hydraulic conductivity.

Q: Can geotextiles be used in drainage applications?: Yes, geotextiles can be used in drainage applications. They are commonly used to improve the performance and longevity of drainage systems by preventing soil erosion, filtering out fine particles, and promoting water flow. Geotextiles can be placed in various drainage applications such as road construction, agricultural drainage, landfills, and erosion control to enhance their effectiveness and efficiency.

Q: What are the different geotextile manufacturing processes?: There are several different geotextile manufacturing processes, including needle punching, thermal bonding, and weaving.

Q: Can geotextiles be used in flood protection projects?: Yes, geotextiles can be used in flood protection projects. Geotextiles are often used as a component in flood control measures due to their ability to effectively filter and drain water while preventing soil erosion. They can be employed in various applications such as erosion control, slope stabilization, and shoreline protection, helping to mitigate the impact of floods and minimize damage to infrastructure and property.

Q: What are the maintenance requirements for geotextile-reinforced slopes?: The maintenance requirements for geotextile-reinforced slopes include regular inspection to check for signs of erosion or damage, ensuring proper drainage to prevent water accumulation, and promptly addressing any issues such as tears or slippage of the geotextile. Additionally, vegetation control may be necessary to prevent root intrusion and maintain slope stability. Regular monitoring and maintenance activities are essential to ensure the long-term effectiveness and performance of geotextile-reinforced slopes.

Q: Where the detection of geotextiles more authoritative: To the authority must find the authority of the body, the international authority was undoubtedly SGS, geotextile common test such as area weight, tear strength, puncture strength.

Q: Do you have to have a mattress on the geotextile?: 1, geotextile must be washed back to fill or sand protective layer and light compaction to prevent the subsequent construction of the destruction of geotextile, punctured and so on. But also a transition zone, to ease the upper load on the geotextile extrusion, tensile force and so on. 2, "Geotextile Construction Code QB / SNGSG-2004" and "Geosynthetics Application Technical Specifications GB / T-2017" backfill requirements: 1) timely backfill materials, backfill stone maximum drop of not more than 300mm, Heavy earth stones should not roll on the slope of the rolling; 2) fill the compaction should meet the design requirements, backfill 300mm loose layer, light compaction. 3, geotextile introduction: 1), geotextile by synthetic fiber through acupuncture or weaving made of permeable geosynthetics. Finished cloth for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a woven geotextile and non-woven geotextile. Advantages: geotextile with excellent filtration, drainage, isolation, reinforcement, anti-seepage, protection, with a light weight, high tensile strength, good permeability, high temperature, resistance to Freezing, anti-aging, corrosion-resistant advantages. 2), Disadvantages: in the rigid base waterproof requirements are not applicable (tensile rate does not meet the requirements), easy to break, scratches and so on.

Q: What are the benefits of using geotextiles in road construction?: Geotextiles offer several benefits in road construction. Firstly, they enhance the stability and durability of the road by acting as a reinforcement layer, distributing loads and preventing the mixing of different layers. Secondly, geotextiles improve drainage by allowing water to pass through, reducing the risk of water damage and prolonging the life of the road. Additionally, they help control soil erosion and prevent the loss of fine particles, which can lead to the formation of potholes and cracks. Overall, geotextiles contribute to cost-effective and sustainable road construction, increasing the lifespan and performance of the road infrastructure.
