Compacted Soil Liner Interface Strength Importance
This paper describes an interesting slope failure in a liner system of a municipal solid waste containment facility during construction because the sliding interface is not the geomembrane (GM)/compacted low-permeability soil liner (LPSL) but a soil–soil interface within the LPSL. Some of the lessons learned are as follows: (1) compaction of the LPSL should ensure that each lift is kneaded into the lower lift so a weak interface is not created in the LPSL; (2) the LPSL moisture content should be controlled so it does not exceed the specified value, for example 3–4% wet of optimum, because it can lead to a weak interface in the LPSL; (3) drainage material should be placed over the GM from the slope toe to the top to reduce the shear stresses applied to the weakest interface; and (4) equipment should not move laterally across the slope if it is unsupported but up the slope while placing the cover soil from bottom to top.
