Provides insight, guidance, and confidence in properapplications of geosynthetic clay liners (GCLs) in containmentsystems for liquid, solid, and hazardous waste containment systems.Summarizes the types of products, special test procedures developedover the last several years, and results of studies of hydraulic,chemical compatibility and stability issues.

The text (18 peer-reviewed papers) progresses from specialtesting procedures, shear strength and creep testing results,hydraulic conductivity testing, chemical compatibility issues, andspecification suggestions for GCL applications. The paper Effectof Swell Pressure on GCL Cover Stability indicates greaterswell pressure than typical overburden loading provides, which maycompromise slope stability. The papers on shear strength and longterm creep also provide important insight into slope stabilityissues.
