Enhanced Subtitle D design standard composite liner

Abstract

An enhanced composite liner system to be employed under waste management units and comprised of an upper flexible membrane liner component (2), an intermediate bentonite layer component (3), and a lower compacted soil liner component (1). The bentonite layer component (3) is bonded to the flexible membrane liner component (2). The flexible membrane liner component (2) utilizes overlapping seams (4) sealed by the bentonite layer component (3) to join the sheets or panels of the flexible membrane liner. The overlapping seams (4) are arranged shingle fashion in the downslope direction of the liner surface. The use of the bentonite layer component enhances direct and uniform contact between the flexible membrane liner component (2) and the underlying compacted soil liner component (1).
