non woven needle punch geotextile
Product Description
The products have excellent water permeability, filterability, and durability. They can be widely applied on railways, highways, gymnasiums, embankments, hydraulic structures, tunnels, coastal beaches, reclamations, environment protective projects, etc.
Functions
For the good air permeability and water permeability of geotextile, the water flow passes through it to effectively stop sand from running down.
The geotextile owns good water transmissibility. It can form drain channels within the soil and discharge the surplus liquid and air in the soil structure.
The geotextiles are used to enhance the tensile strength and non-deformability of soil mass as well as the stability of buildings to improve the quality of soil.
The concentrated stress is spread, transmitted or resolved effectively to prevent the soil mass be destroyed by external force.
To prevent the mix between upper and lower level of sandrock, soil mass and concrete.
The mesh is not easy to be blocked—because the network structure formed by indefinite form fibrous tissues has compliance and motility.
High water permeability—under water pressure, the product still maintains good water permeability.
Corrosion resistance—to take polypropylene or polyester and other chemical fiber as raw materials, the product is acid and alkali resistant, non-corroding, not damaged by worms and oxidation resistant.
Easy construction—the weight of product is light, the operation is convenient and the construction is easy.
