What is the lifetime of a GCL?
To the best of our knowledge, the natural and synthetic components of a GCL will uphold far into the future, likely over 100 years under normal conditions of soil burial. While conclusive data is impossible to provide, the bentonite in GCLs is already extremely old (millions of years), and the synthetic geotextiles are made of chemically stable polymers which resist long-term degradation.
