Abstract
A geosynthetic tufted drain barrier (GTDB) for preventing vertical migration of fluids. On a substantially impermeable woven or non-woven continuous layer is disposed a membrane. The tensile strength of the impermeable layer is at least 5 lbs/lineal ft (3.0 kg/lineal m). The permeability of the membrane is no greater than 10cm/sec. Tufted tensile elements are attached to the membrane, each one being attached to the membrane at a density of at least 25 tufted tensile elements per square foot (30 square cm). The tufted tensile elements are formed in rows and are disposed at a density of at least four rows per square foot (30 square cm). Infill material can be introduced to the tufted tensile elements. The drain barrier may be constructed with integrated letters, logos, and signage and one or more colors.
