1 Scope
This document specifies an index test method that covers laboratory measurement of
water flux through saturated clay geosynthetic barrier (GBR-C) specimens using a flexible wall
permeameter at constant head.
This test method is applicable to GBR-C products with no additional sealing layers
attached (e.g. polymeric or bituminous).
This test method specifies a measurement of flux under a prescribed set of conditions that can be used for manufacturing quality control.
The test method can also be used to check conformance.
The flux value determined using this test method is not considered to be representative of
the in-service flux of a GBR-C.
