Abstract
A geosynthetic clay liner is provided for installation in landfill sites equipped with lower drainage systems. The self-sealing bentonite mat precludes substantial migration of bentonite downward during activation thereby avoiding clogging of the drainage systems with activated bentonite. Overlap extensions disposed on outer edges of the liners effectively contain the activated bentonite. The bentonite mat, or geosynthetic clay liner, does not require a first protective layer of geotextile material disposed below the bentonite clay liners to protect the drainage system.
