Geosynthetic barriers. Characteristics required for use in the construction of tunnels and associated underground structures1 Scope This document specifies the characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separation layer in the construction of tunnels and associated underground structures, and the appropriate test methods to determine these characteristics. The intended use of these products is to control the leakage of fluid through the
