Geosynthetic Clay Liner
index flux, hydraulic conductivity
This test method involves permeation of a 100-mm (4in.) diameter GCL test specimen using an incompatible liquid. A bladder interface device is used to isolate the incompatible liquid from the test apparatus. The specimen is set up in a flexible-wall permeameter and subject to prescribed cell and back pressures. Flow vs. time is measured and recorded. Two scenarios can be followed 1: using water to saturate the specimen and initial flow and 2: using incompatible liquid to saturate and initial flow.
