Clay Geosynthetic Barriers. Characteristics required for use in the construction of underground structures (other than tunnels and associated structures) Ingestion-build-264231 BS EN 61375 is a1 Scope This document specifies the characteristics of clay geosynthetic barriers (GBR C) as well as multicomponent geosynthetic clay barriers (e. g. a GBR C with a polymeric or bituminous geosynthetic barrier attached to it), when used as fluid barriers and separation layer in the construction of underground structures (other than tunnels and associated structures), and the appropriate test methods to determine these characteristics.
