Function:
■ Geotextile has good air and water permeability to let water flow through it so as to effectively control sandrock running-down.
■ Geotextile has good water transmissibility, it can form drainage channels inside soil mass to drain redundant liquid and air out of the soil mass.
■ Geotextile helps to enhance the soil mass' tensile strength and non-deformability and structural stability so as to improve soil mass quality.
■ It can effectively make the concentrated stress diffuse, transfer or decompound, and prevent the soil mass against the destruction of outside force.
■ It can prevent the mixture of sandstone, soil mass and concrete of upper and lower layers.
■ Its mesh is hard to jam by virtue of the compliancy and motility of the reticulation formed by indefinite form fibrous tissue.
■ High water permeability-it can keep good water permeability even in the pressure of soil and water.
■ Corrosion resistant-it is made from polypropylene fiber or terylene or other chemical fiber, featuring resistance to acid and alkali and oxidation, non-corroding, no worm-eaten.
■ Easy construction-low weight, easy operation, simple construction.

1) Specification is decided by mass-area ratio. When the practical specification is between the neighboring specifications in the table, the related check indicators will be calculated according to the interpolation method; if the product specification is beyond the table given scope, the check indicators will be decided by the supplier and demander.
2) Stand value is subject to the design or agreement. 3) If there is any alteration for the above technical data, we won't give further notice. 4) Other specification is available as customer required. |
