Abstract: A geotechnical structure that includes a first body of soil having a first unsaturated concentration of moisture. There is also a second body of soil, which includes a second unsaturated concentration of moisture that is different from the first concentration. A moisture barrier is interposed between the first body of soil and the second body of soil. The moisture barrier includes an upper and lower layer that draw water laterally. A medial capillary barrier layer prevents traverse moisture migration between the first and second bodies of soil. Moisture migration both upwardly and downwardly is thus prevented, and water in the first and second bodies of unsaturated soil is drained laterally to reduce pore water pressures in the first and second bodies of soil.

Abstract: Waste sites are capped or covered upon closure. The cover structure incorporates a number of different layers each having a contributory function. One such layer is the barrier layer. Traditionally the barriers have been compacted soil and geosynthetics. These types of barriers have not been successfully implemented in unsaturated ground conditions like those found in dry climates. Capillary barriers have been proposed as barrier layers in dry environments, but the divergence length of these barriers has been found to be inadequate. An alternative to the capillary barrier is a anisotropic capillary barrier. An anisotropic capillary barrier has an increased divergence length which results in more water being diverted laterally preventing the majority of water from percolating in a downward direction through the barrier.
