Product performance

  Excellent anti filtration property, so that the soil material under seepage pressure will not be lost; Good drainage ability, allowing water to be discharged through its permeable channel body; Good elongation and corrosion resistance; Good reinforcement performance can increase the stability of the building.


Applicable scope

  Roads, railways, airports, water conservancy projects, environmental protection projects, electric power projects, waterproof materials, ground leather substrates, etc.
