The geotextile permeability tester is a testing device designed and developed using the JIGAOTEST system, used to measure the water permeability of geosynthetic materials and related composite materials in the vertical direction.
Application
It is used to measure the characteristics of the plastic drainage plate in the plane direction of the water flow under the specified pressure. During the test, seepage was carried out under the condition that the lateral pressure of the sample was 350kPa and the hydraulic gradient i=0.5. and the water seepage of the sample in a certain period of time was measured.
