White 100% polyester non-woven geotextile for road dam construction
Short Description:
Non-woven geotextiles have many advantages, such as ventilation, filtration, insulation, water absorption, waterproof, retractable, feel good, soft, light, elastic, recoverable, no direction of fabric, high productivity, production speed and low prices. In addition, it also has high tensile strength and tear resistance, good vertical and horizontal drainage, isolation, stability, reinforcement and other functions, as well as excellent permeability and filtration performance.
Products Description
Non-woven geotextiles are water-permeable geosynthetic materials made of synthetic fibers by needling or weaving. It has excellent filtration, isolation, reinforcement and protection, while high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance. Non-woven geotextiles are widely used in many projects, such as roads, railways, embankments, earth-rock DAMS, airports, sports fields, etc., to strengthen weak foundations, while playing the role of isolation and filtration. In addition, it is also suitable for reinforcement in the backfill of retaining walls, or for anchoring the panels of retaining walls, as well as building wrapped retaining walls or abutments.
Feature
1. High strength: under the same gram weight specifications, the tensile strength of long silk spunbonded needled nonwoven geotextiles in all directions is higher than that of other needled nonwovens, and has higher tensile strength.
2. Good creep performance: This geotextile has good creep performance, can maintain stable performance in long-term use, and is not easy to deformation.
3. Strong corrosion resistance, aging resistance and heat resistance: long silk spunbonded needled nonwoven geotextile has excellent corrosion resistance, aging resistance and heat resistance, and can be used for a long time in harsh environment without damage.
4. Excellent water conservancy performance: its structural pores can be effectively controlled to achieve a certain permeability, which is suitable for projects that need to control water flow.
5. Environmental protection and durable, economic and efficient: compared with traditional materials, long silk spunbonded bonded geotextile is more environmentally friendly, can be recycled and reused, reduce the environmental burden, and high durability, long-term exposure can still maintain stable performance, greatly reducing maintenance costs.
6. Easy construction: convenient construction, do not need complex technology and equipment, save manpower and material resources, suitable for projects in a hurry.
Application
Used in the area of highway, railway, dam, coastal beach for rein forcement, filtration, separation and drainage, especially used in salt marshes and garbage burying field. Mainly in filtration, reinforcemnent and separation.
