Achieving zero leaks on a budget with geomembranes

June 1, 2017  |  Containment, Feature, Separation

For more than 30 years, the geomembrane industry has been told that “all geomembranes leak” (Giroud 1984), as if this were some foregone conclusion no matter what might happen from geomembrane manufacturing to the time it is put into service. But recently, the idea of “zero leaks” has been a…
Part 2: New design models for MSE walls and slopes

June 1, 2017  |  Case Studies, Containment, Erosion Control, Feature, Reinforcement

Introduction The design of many geotechnical structures is based on limit-state conditions. For example, in designing gravity walls, the load exerted by the retained soil on the wall is based on an assumed active state of stresses. That is, the wall moves sufficiently outward, enabling the retained …
