| Example of the Use of a Geomembrane as a Liner |
Natural Lining Materials
Natural linings used to control or prevent seepage through embankment dams can include compacted earth (typically clays and silts with low permeabilities) in conjunction with other seepage barriers such as steel, concrete, gunite, asphaltic concrete, or soil cement.
Synthetic Lining Materials
