Abstract:
1. A geosynthetic tufted drain barrier (GTDB) for preventing vertical migration of gases and fluids, constraining soil particles, providing drainage, and retaining granular materials with predefined permeability, comprising: a) a single, substantially impermeable continuous layer having a plurality of tufted tensile elements integral thereto, at least a portion of said plurality of tufted tensile elements having a predetermined length and gauge spacing co-dependent on the thickness and gradation of filler material, thickness of GTDB, angle and length of slope on which said GTDB is disposed, and amount of liquid in-plane flow; b) a membrane having at least one of the group of attachment stated: liquid applied onto, laminated, and integrated with, said substantially impermeable continuous layer; and c) filler material proximate said plurality of tufted tensile elements and partially constrained thereby, said filler material for facilitating draining and being selected from the group: sand, stone, gravel, rubber, boiler slag, asphalt, recycled concrete, recycled rubber tires, recycled glass, and expansive minerals.
