Géotextile non tissé aiguilleté PP

Describe

Geotextile, also known as geofabric or geosynthetic material, is a permeable geosynthetic material made from synthetic fibers through a needle-punching process. The fibers are opened, carded, and laid into a web, then reinforced into fabric by needle punching.

Polypropylene (PP) non-woven needle-punched geotextile is produced using high-quality short fibers through the needle-punching process. PP offers better moisture resistance, abrasion resistance, ventilation, and drainage performance compared to PET. Polypropylene fibers are lighter in weight than polyester fibers.

Features

• High Strength, due to the use of plastic fibers, it maintains sufficient strength and elongation in both dry and wet states.
• Corrosion Resistance, It can endure long-term corrosion in soils and water with varying pH levels.
• High-Temperature & Freeze Resistance, Aging Resistance: Resistant to high temperatures, freezing conditions, and aging.
• Excellent Permeability, the gaps between fibers ensure good water permeability.
• Microbial Resistance, unaffected by microorganisms and insect damage.
• Easy Installation, lightweight and flexible, making transportation, laying, and construction convenient.

Function

• Breathable & Permeable: Allows water to pass through while preventing soil and sand erosion.
• High Water Conductivity: Forms efficient drainage channels to remove excess liquids and gases.
• High Permeability Under Pressure: Maintains excellent water flow even under soil and water pressure.
• Stress Distribution: Effectively disperses, transfers, or decomposes concentrated stress to protect soil from damage.
• Separation Layer: Prevents mixing between upper and lower layers of sand, soil, and concrete.
• Chemical Resistance: Made of PP or PET fibers, resistant to acids, alkalis, corrosion, heat, and oxidation.
• Lightweight & Easy Installation: Reduces construction time and costs while improving efficiency.
• Reinforcement: Enhances soil tensile strength, deformation resistance, and structural stability, improving soil quality.

Purpose

PP Short-fiber needle-punched geotextile is a widely used geosynthetic material. It is extensively applied in various engineering projects, including:

- Reinforcement of railway roadbeds

- Maintenance of highway pavements

- Protection of embankments and dams

- Separation in hydraulic structures

- Tunnels, coastal tidal flats, and land reclamation

- Environmental protection projects

- Power plants and airport construction
