200g PET Non-woven Geotextile Application
1. High strength and excellent toughness, resistant to stretching and tearing, suitable for complex foundation conditions.
2. Excellent water permeability and filtration performance, effectively blocking sand and preventing soil erosion, stabilizing the soil layer structure.
3. Resistant to acid and alkali, anti-aging, corrosion-resistant, long-term outdoor use does not degrade easily, and has a longer service life.
4. Soft texture and good extensibility, suitable for ground laying, convenient construction, reducing labor and construction cost.
5. Strong isolation and protection effect, buffering load impact, reducing damage risks to roads, dams, etc. engineering.
Chapter 1 Composition of PET Non-woven Geotextile
PET non-woven geotextile is made of 100% polyester (polyethylene terephthalate, PET) chips, formed via melt-spinning, high-speed drafting, and needle-punching without weaving. Its structure consists of continuous PET filaments bonded into a 3D porous network, with no additional binders. The raw material features high molecular stability, while the needle-punched structure provides uniform porosity and mechanical strength.

Chapter 3 Application Advantages of PET Non-woven Geotextile
1.High Mechanical Performance: High tensile and tear strength, resisting deformation under heavy loads and complex stress.
2.Efficient Filtration & Drainage: 3D porous structure blocks soil particles while allowing water passage, preventing soil loss and water accumulation.
3.Superior Chemical Stability: Resists acids, alkalis, and corrosion; adapts to harsh environments like landfills and coastal projects.
4.Excellent Durability: Anti-aging, UV-resistant, and creep-resistant, maintaining performance for over 20 years in outdoor applications.
5.Good Compliance & Workability: Soft and flexible, fitting uneven surfaces; easy to cut and install, reducing labor costs.
6.Eco-friendly & Recyclable: Non-toxic, pollution-free, and recyclable, aligning with sustainable construction goals.
Chapter 4 Typical Application Scenarios of 200g PET Non-woven Geotextile
1.Road & Railway Engineering: Used for roadbed separation, reinforcement, and drainage; prevents mixing of subgrade and base, enhancing pavement stability.
2.Water Conservancy Projects: Applied in dams, channels, and reservoirs as filtration and drainage layers; prevents soil erosion and ensures structural safety.
3.Landfill & Environmental Protection: Serves as protection and filtration layers for liners; isolates waste, prevents leachate leakage, and safeguards the environment.
4.Slope Protection & Greening: Stabilizes slopes, prevents soil loss, and supports vegetation growth; ideal for highway slopes and riverbanks.
5.Building & Civil Engineering: Used in foundation isolation, roof drainage, and tunnel protection; enhances structural durability and waterproofing.
Chapter 6 Cooperation with Geomembrane in Applications
In engineering, 200g PET geotextile and geomembrane (e.g., HDPE) form a geosynthetic composite system for anti-seepage and protection. The geotextile is laid above and below the geomembrane: the lower layer isolates the foundation, prevents sharp objects from puncturing the membrane, and provides drainage; the upper layer protects the membrane from construction damage and UV aging. During installation, overlap geotextile seams by ≥20 cm and geomembrane seams by ≥10 cm, with geotextile covering membrane seams to avoid direct sunlight. This combination significantly improves anti-seepage reliability, extends service life, and reduces maintenance costs.
