Overview
Geotextile Introduction
Geotextile has excellent permeability, acquired, durability, which can be widely used in railway ,highway, movement hall,Dams,hydraulic structures hence hole, coastal shoal, reclamation,environmental protection and other projects. The main products are Synthetic staple fibers needle punched nonwoven geotextiles and split film yarn woven geotextiles.

Geotextile Function
Pp Thermally Bonded Geotextile For FilterationPp Thermally Bonded Geotextile For Filteration
The raw materials are polypropylene or polyester fiber and so on which can not be eaten by moth or oxidation.
The nets hole is not easy to jam---because the net structure is made of generalized fiberous tissue that has adaptability and moveability.
1. excellent air permeability and water permeability to resist the soil erosion effectively
2. a better specification to guide the water and gas to discharge from the soil.
3. a high tensile strength and non-deformability to strengthen the stability of building structure and improve the soil quality.
4. effectively focus on the diffusion, transfer and decomposition and prevent the soil damage.
5. to prevent the lower sand, soil and concrete from mixing.
6. make construction be simple---light weight, easy to use, simple construction.
7. acid and alkali resistant, no corrosion
