Hydration of Geosynthetic Clay Liners for Use in Antarctica
Geosynthetic clay liners (GCLs) have been used at Casey Station, Antarctica as part of a composite liner system to contain hydrocarbon-contaminated soils. The extreme Antarctic environment provides many challenges regarding the use of GCLs, including: high permeability subsoil with considerable gravel and cobbles, extreme cold air temperatures, and very arid conditions. All of these factors make it very difficult for a GCL to fully hydrate, which is needed to create a good hydraulic barrier and provide proper containment. Three sets of GCL hydration tests are to be evaluated: sacrificial GCL coupons, field hydration tests and laboratory hydration tests. Laboratory based testing is reported and evaluated, comparing different GCL materials using Antarctic subsoil at standard proctor optimum water content. All testing is completed at 13 kPa of pressure, to resemble the conditions experienced in the field. Four different types of GCL are compared, two of which are currently used in the field, and two are possible alternative GCLs. Early data suggests that proper GCL hydration is achievable in Antarctica if special attention is given to these unique environmental and site specific conditions. All GCLs tested showed promising results; testing is ongoing.
