Needle-punched geotextile for landfill

Product Description

This Landfill engineering needle-punched geotextile is engineered from PET/PP fibers through advanced needle-punching technology, delivering high mechanical strength, aging resistance, and chemical stability. Designed as a protective layer for geomembranes, it effectively resists puncture from gravel or sharp fill materials while enhancing landfill structural integrity through integrated filtration, drainage, separation, and reinforcement functions. With optimized permeability and anti-clogging properties, it ensures efficient drainage and fine particle retention. Suitable for both dry and wet conditions, it is a durable solution for landfill liners and environmental containment systems.

Key Specifications

Features

High Durability: Made from premium materials, geotextiles exhibit excellent durability and aging resistance, ensuring long-term performance stability.

Easy Installation: With superior flexibility and adaptability, they can be easily cut and spliced to suit complex terrain requirements.

Cost-Effective: Compared to traditional impermeable materials, geotextiles are more economical, significantly reducing road construction costs.

Function

• Filtration: Effectively prevents soil particles from mixing with liquids, maintaining soil stability. In landfills, geotextiles control leachate flow and minimize fine particle loss.
• Drainage: Provides efficient drainage channels for leachate, reducing moisture buildup within the landfill body. This lowers overall moisture content and extends landfill service life.
• Separation: Acts as a reliable barrier between different material layers, preventing cross-contamination. In landfill construction, geotextiles isolate waste from surrounding soil, minimizing environmental interaction.

Purpose

In landfill construction and operation, geotextiles are primarily used in the following aspects:

(1) Bottom liner protection: Installed at the landfill base to prevent leachate from seeping into groundwater, safeguarding water resources.

(2) Sidewall reinforcement: Enhances slope stability by preventing soil slippage or collapse caused by waste weight.

(3) Leachate management: Directs leachate flow within the landfill to ensure proper drainage and avoid environmental issues from liquid accumulation.
