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.


Technical parameter

Reference standard: GB/T17639-2008
