Geotextile for seepage
Dec 12, 2016

Geotextile for seepage as impervious to plastic film substrate, and non-woven fabric composite geo impervious material, its seepage prevention of seepage control performance depends primarily on the plastic film. Impervious plastic film at home and abroad, mainly of polyvinyl chloride (PVC) and polyethylene (PE), which is a kind of flexible materials for polymer chemistry, the proportion of small, extension of strong, high Adaptive deformation, corrosion resistance, low temperature resistance, good freeze resistance. Its main mechanism is to plastic film of not through water partition dam leaking channel, to its larger of tensile strength and extends rate bear hydraulic and adapted dam body deformation; and no spinning cloth also is a polymer short fiber chemical material, through acupuncture or hot stick forming, has high of tensile strength and extension, it and plastic film combined Hou, not only increases has plastic film of tensile strength and anti-puncture capacity, and due to no spinning cloth surface rough, increases has contact surface of friction coefficient, conducive to composite geo film and the cover of stable. Also, they are good for bacteria and chemical corrosion resistance, acid, alkali and salt corrosion.


Geotextile for seepage-proof function:

Geotextile has good water properties, it can be formed inside the soil drains, excess liquids and gases discharged within the soil structure.

Effective will focus on stress distribution, transmission or decomposition, and prevent the soil from external forces and destroyed.

Prevents mixing between the upper and lower layers of sand, soil and concrete.

Under the pressure of high water permeability in soil-water, can still maintain good water permeability

Simple construction-low weight, easy to use, simple construction
