Isolation of building materials with different physical properties, so that there is no loss or mixing between two or more materials, maintain the overall structure and function of the material, and strengthen the load bearing capacity of the structure.
When the water flows from the fine soil layer into the coarse soil layer, its good permeability and water permeability are used to make the water flow through, and effectively intercept soil particles, fine sand, small stones, etc., to maintain the stability of soil and water engineering.
It is a good water conductive material, which can form a drainage channel inside the soil and remove excess liquid and gas in the soil structure.
The use of needled geotextiles to enhance the tensile strength and deformation ability of the soil mass, increase the stability of the building structure, and improve the quality of the soil mass.
Effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being damaged by external forces.
Cooperate with other materials (mainly asphalt or plastic film) to form an impervious barrier in the soil layer (mainly used for highway resurface, repair, etc.).
Can be widely used in water conservancy, hydropower, highways, railways, ports, airports, sports venues, tunnels, coastal beaches, reclamation, environmental protection and other fields, play isolation, filtration, drainage, reinforcement, protection, sealing role.

It is a non-woven geosynthetic material made of staple fiber using needle punching technology. It is widely used in civil engineering, water conservancy, environmental protection, and agricultural applications.
It is made of chemical fibers such as polypropylene or polyester. These raw materials provide excellent acid and alkali resistance, prevent corrosion and moth damage, and ensure outstanding anti-oxidation features.
No. The network structure is formed by amorphous fiber tissue, which has anisotropy and motility, ensuring that the mesh is not easily blocked while keeping high water permeability.
It isolates different building materials to prevent mixing, maintains their structure, and acts as a water conductor to create drainage channels inside the soil to remove excess liquid and gas.
The product is designed and manufactured according to the GB/T17638-1998 standard, meeting strict quality requirements for civil engineering and environmental applications.
