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.
Material: PP (polypropylene)or Polyester fibers
1)Staple fibers needle punched non woven geotextile
The geotextile is made of polypropylene staple fibers on
cross-laying equipment and needle punched equipment.
Feature: It owns the advantages of acid and alkali resistance, erosion
resistance, aging resistance, large strength, stable size, good
Functions: It mainly applied in water conservancy, road and railway for
strengthening, separation, reversed filter and drainage of projects
2)Filament non woven geotextile
Filament geotextile has features as follows: High strength, good
capacity of elongation and high biology tolerance, alkali
tolerance, acidity tolerance, weather resistance good filtration
and fine drainage capacity etc. Alo it is of low cost, easy in
construction and use effects.
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
7. acid and alkali resistant, no corrosion
