Product Introduction:
Geotextile 200gr is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving.
Classified
by manufacturing process: Needle punched non-woven geotextile, made of polyester short fibers or polypropylene short fibers through needle punching method; Weaving geotextiles made from synthetic fibers such as polyester and nylon through weaving techniques; Non woven geotextiles are made from synthetic fibers such as polyester and polypropylene through thermal bonding or needle punching processes.
Characteristic
1. High strength: Using plastic fibers, it can maintain sufficient strength and elongation in both dry and wet conditions, and can withstand large tensile and compressive forces.
2. Corrosion resistance: It can resist corrosion for a long time in soil and water with different acidity and alkalinity, and adapt to various harsh soil and water environments.
3. Good permeability: There are gaps between the fibers, which have good water permeability, allowing water to pass smoothly while preventing the loss of soil particles.
4. Good antimicrobial properties: It is not damaged by microorganisms or insects, and can maintain stable performance for a long time.
5. Convenient construction: The material is light, flexible, and easy to transport and lay, which can reduce the difficulty and cost of construction.
6. Complete specifications: With a width of up to 9 meters, it is the widest product in China, with a unit area mass of 100-1000g/m ², which can meet different engineering needs.
Role
1. Isolation: Isolate building materials with different physical properties to prevent loss or mixing between two or more materials, maintain the overall structure and function of the materials, and enhance the load-bearing capacity of the structure.
2. Filtration (reverse filtration): When water flows from the fine soil layer into the coarse soil layer, its good breathability and permeability are utilized to allow water to pass through, while effectively intercepting soil particles, fine sand, small stones, etc., maintaining the stability of water and soil engineering.
3. Drainage: It has good water conductivity and can form drainage channels inside the soil to discharge excess liquids and gases from the soil structure.
4. Reinforcement: Enhance the tensile strength and deformation resistance of soil, strengthen the stability of building structures, and improve soil quality.
5. Protection: When water flows on the soil, it can diffuse, transmit or decompose concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.
6. Anti puncture: Combined with geomembrane to form a composite waterproof and anti-seepage material, it plays a role in preventing puncture and protecting the geomembrane from sharp objects.
