Abstract
A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.
