Geotextile Bag

Geotextile bag are double-sided, ironed, needle-punched non-woven bags made primarily from high-molecular-weight polypropylene (PP) or polyester (PET) fibers, crafted through a specialized process. More than just a simple woven bag, they serve as a biodegradable growth medium for plants. Based on local climate conditions, the bag can be filled with soil, sand, preservatives, and other fillers in a scientifically formulated ratio, then seeded with seeds suitable for the local climate. This creates a new product that can restore or create new ecosystems.

Core Structure of geotextile bag:

• 1. Bag Material: High-strength, UV-resistant non-woven fabric. This material possesses excellent physical properties:
  • Water Permeability: Allows water to pass through, preventing water accumulation and hydrostatic pressure within the slope.
  • Soil Impermeability: Prevents soil loss from the bag, maintaining structural stability.
  • Anti-aging: UV-resistant ingredients are added to ensure long-term field use (typically designed for a lifespan of 70-120 years).
  • Flexibility: Able to adapt to slight deformations in the foundation without breaking.
• 2. Functional Layer (Critical): Many high-end Geotextile bag have a seed layer or grass mat attached to the outside. This layer contains a pre-mixed mixture of grass seeds, fertilizer, and water-retaining agents. Once the right conditions (water and suitable temperature) are met, the seeds germinate, and the roots penetrate the bag, tightly connecting the individual Geotextile bag into a single unit, forming a permanent ecological slope.
• 3. Filling: Typically made from locally available materials, a mixture of sand, nutrient soil, and fertilizer provides a foundation for plant growth.

• 1. Eco-Friendly: They restore natural vegetation, improve the ecological environment, promote biodiversity, and are pollution-free.
• 2. Convenient Construction: The materials are lightweight and easy to transport, and the construction process is simple, requiring no large machinery and resulting in fast construction.
• 3. Durability: They are UV-resistant and corrosion-resistant, with a designed long service life.
• 4. Water-Permeable and Soil-Retaining: They effectively drain water while firmly locking in the soil to prevent soil erosion.
• 5. Strong Self-Healing Ability: Even if partially damaged, the flexible structure and integrated connections prevent overall collapse, and plant roots can regrow and repair the damage.
• 6. Excellent Landscape Effect: They create a naturally green, vegetated slope that blends harmoniously with the surrounding environment.

Geotextile bag have a wide range of applications, covering almost all scenarios requiring slope protection and greening.

1. Slope Engineering:

• Highway and Railway Slopes: They replace traditional mortared stone and concrete slope protection, addressing engineering damage and creating "green corridors" along the road.
• Riverbank and Lakebank Slope Protection: They prevent erosion while restoring shoreline ecology and providing habitats for aquatic life.
• Reservoir and Dam Slopes: They reinforce soil, prevent soil erosion, and beautify the reservoir area.

2. Landscape:

• Rooftop Greening: They serve as lightweight planting media for rooftop gardens and vertical greening.
• Vertical Green Walls: They create ecological walls and unique three-dimensional landscape effects.
• Rooftops and Retaining Walls: They are used to create micro-topography and artistic retaining walls in gardens.

3. Ecological Restoration of Special Difficult Sites:

• Mine Reforestation: They are used to restore vegetation in harsh conditions such as tailings dams and mining incisions, and are a key technology for mine remediation.
• Landfill Cover: Serves as a cover layer, stabilizing the landfill and enhancing greening.
• Saline-alkali Land and Rocky Slopes: By filling with imported soil and a specially formulated seed layer, a plant growth environment is created even in harsh soil conditions.

4. Military and Disaster Prevention:

• Military Shelters: Rapidly construct flexible fortifications.
• Geological Disaster Management: Used for emergency response and ecological restoration at sites of landslides, collapses, and other disasters.
