Product Description

Introduction to Geotextile 

Geotextile is a type of geosynthetic material made of polyester and polypropylene fibers, classified into short-filament and long-filament types. The 300g specification is widely adopted in construction projects. Featuring excellent water permeability, tensile strength and anti-aging performance, it is easy to install and commonly used in roadbeds, dams, river channels, landfills and other infrastructure.
It serves four core functions: filtration, drainage, separation and protection. Laid between soil layers, it blocks fine soil particles while draining accumulated water smoothly to prevent soil softening and settlement. It separates fillers of different grain sizes to stop sand and soil from mixing and damaging foundation structures. When placed on slope protection or outside anti-seepage liners, it buffers water erosion and avoids damage to geomembranes.
300g geotextile balances tensile performance and cost efficiency. It fits road reconstruction, artificial lake anti-seepage, river slope stabilization and residential green drainage. Resistant to acid, alkali and rot, it can last for decades underground. Installation only requires simple flat laying and overlapping without complex machinery, cutting long-term maintenance costs. As an essential basic material, it plays an irreplaceable role in infrastructure and environmental anti-seepage projects.

Filtration Application

Geotextiles are mainly used for water and soil filtration in construction sites, commonly laid on river embankments, dams, foundation pits, drainage blind ditches and other parts. With the uniform microporous structure of the fabric, it allows water to pass through while retaining soil particles. It can smoothly drain seepage and accumulated water in the soil and intercept fine soil particles to prevent the soil layer from being washed and hollowed out by water flow. It can replace traditional sand and gravel filter layers, avoid blockage failure, stabilize soil structure, prevent slope sliding, foundation settlement and soil erosion, and greatly improve the overall stability of civil engineering projects.

Drainage Application

Geotextiles are widely used as auxiliary drainage layers in roadbed, tunnel, retaining wall, landfill and other construction projects. Featuring a fluffy fiber structure and excellent water conductivity and permeability, it can quickly collect accumulated water and fissure seepage in soil layers, form continuous drainage channels and discharge water out of the structure in a timely manner. It effectively reduces soil pore water pressure, avoiding roadbed boiling, tunnel water seepage and wall softening. With simple construction, uniform and anti-clogging drainage, it keeps engineering structures dry and stable and reduces water seepage risks and later maintenance work.

Isolation Application

Geotextiles are mainly used for layered isolation in road construction, site backfilling and dam filling projects, laid between soft foundations, fill soil, sand and gravel cushions and anti-seepage layers. It completely separates fillers of different materials and particle sizes, preventing the mixing of soft soil and sand and gravel, and avoiding uneven foundation settlement and reduced bearing capacity caused by coarse aggregate embedding. It ensures uniform thickness and clear layering of structural layers, improves roadbed compaction quality and flatness, and eliminates quality defects caused by mixed base materials.

Protection Application

Geotextiles serve as protective buffer layers in river slope protection, dam facing and geomembrane anti-seepage projects. With high toughness, tensile resistance and erosion resistance, it covers the surface of geomembranes and slope soil to buffer water impact, wind and sand erosion, and stone extrusion and friction. It prevents sharp gravel from puncturing geomembranes and rainwater from washing away slope soil, and reduces structural damage and aging caused by stress concentration. Featuring convenient installation, it effectively protects anti-seepage and slope structures, improves project durability and extends the service life of civil anti-seepage and slope protection works.

Product Features

1.Excellent water permeability: Uniform pores between fibers allow water to drain rapidly, release hydrostatic pressure and prevent structural damage caused by accumulated water.
2.Reliable filtration performance: Retains fine soil particles while permitting water passage, stops soil loss and stabilizes subgrade soil structure.
3.High tensile strength and crack resistance: Interwoven fiber structure provides stable tensile capacity, adapts to uneven foundation settlement and resists tearing.
4.Corrosion and aging resistance: Tolerates acid, alkaline wastewater and soil erosion, resists microbial decomposition and maintains performance under long-term outdoor exposure.
5.Effective separation function: Separates soil layers of different particle sizes, as well as soil and geomembranes, preventing material mixing and ensuring independent performance of each layer.
6.Abrasion and puncture resistance: The fibrous layer offers buffer protection against impact from gravel and hard objects, preventing puncture damage to underlying geomembranes.
