Product Introduction
1.Basic attributes
4oz Non Woven Geo Textile Filter Fabric made from polymer materials and processed through non-woven technology, with a specification of 4 ounces. Its structure is characterized by the formation of evenly distributed pores through special processes. The material itself has the characteristics of anti-aging, acid and alkali resistance, chemical corrosion resistance, etc., and can adapt to a variety of complex use environments such as soil burial, water environment immersion, etc.
2.Core functions
Filtering and interception: Relying on a uniform pore structure, it accurately intercepts solid impurities such as soil particles and sand and gravel, while ensuring smooth infiltration and discharge of water and liquids, achieving the core filtering function of "blocking impurities and flowing water", and maintaining the stability of the system's drainage function.
Scene adaptation support: It can be directly applied to scenarios such as roadbed drainage layer, slope protection filter layer, underground pipe network backfill filter layer, landscape drainage system, etc., providing functional support for water and soil separation and anti blocking needs of different projects.
3.Main features
Construction convenience: The 4-ounce lightweight design significantly reduces the difficulty of handling and cutting, and the laying process is flexible and efficient, especially suitable for small-scale operations or construction in complex terrain areas, which can reduce labor input and construction time.
Long term durability: The chemical stability of polymer materials makes them less prone to aging and damage due to environmental erosion during long-term use, effectively extending the service life of the filtration system and reducing maintenance and replacement costs in the later stages.
Functional stability: The non-woven process ensures uniform pores and is not easily deformed, avoiding the influence of structural changes on filtration efficiency and maintaining stable retention and permeability performance for a long time.

Product Application
1.In the field of roadbed engineering
In the roadbed drainage system of highways and railways, 4-ounce non-woven geotextile filter fabric can be laid between the roadbed soil and the drainage layer. Its uniform pore structure can accurately intercept soil particles in the roadbed, prevent fine soil loss from blocking drainage channels, and ensure smooth infiltration and discharge of rainwater and groundwater, avoiding softening of roadbed water and enhancing the stability and durability of the roadbed structure.
2.Slope protection field
For ecological protection projects such as mine greening, highway slopes, and river slopes, this fabric can be used as a filter layer to be laid on the soil surface of the slope or below the vegetation planting layer. It can intercept sand and gravel impurities in slope soil, prevent soil erosion, and allow water to penetrate into deep soil or drainage systems, providing a suitable water environment for slope vegetation growth and assisting in slope ecological restoration and protection.
3.Underground pipeline engineering field
In the backfilling construction of underground pipelines such as sewage pipes, rainwater pipes, and cable trenches, they are laid between the backfill soil and drainage layer around the pipes. It can effectively isolate soil and pipelines, intercept particle impurities in backfill soil, prevent soil loss or blockage of drainage gaps around pipelines, and discharge accumulated water in trenches, reducing soil pressure on pipelines and protecting the safe operation of underground pipelines.
4.Landscape engineering field
In the drainage design of landscape facilities such as garden water features, artificial lakes, flower beds and borders, this fabric can be used for laying filter layers. It can intercept sediment and impurities in the landscape soil, avoid turbid water features or blocked drainage outlets, and ensure smooth discharge of excess water, maintaining soil moisture balance in the landscape area and providing convenience for plant growth and landscape maintenance.
5.In the field of agricultural water conservancy
In the anti-seepage filtration system of irrigation channels and reservoirs in farmland, it can be laid between the anti-seepage layer and the soil. By intercepting soil particles to prevent the anti-seepage layer from being pierced or blocked, and ensuring the smooth discharge of seepage or rainwater in the channel, the problem of soil salinization around the channel is reduced, and the efficiency of agricultural water conservancy facilities is improved.
4-ounce non-woven geotextile filter fabric plays a key role in various fields such as roadbed engineering, slope protection, underground pipeline network, garden landscape, and agricultural water conservancy due to its precise filtration performance, lightweight and easy construction characteristics, and good durability. It effectively solves problems such as soil and water separation, blockage prevention, and structural protection in different engineering scenarios through its core function of "blocking impurities and flowing water". It not only ensures the stability and safety of engineering structures, but also provides reliable support for ecological restoration, landscape maintenance, and agricultural production. It is a practical material for various filtration demand scenarios.
