WebThe cation exchange capacity (CEC) of a GCL is small when compared to a clay liner. In essence, where a barrier is required that requires either an absorptive capacity or a long breakthrough time, a GCL alone will not provide adequate protection. In these circumstances, a design will also need a low permeability attenuation layer. WebAug 31, 2024 · Abstract. This paper examines the gas flow performance of needle-punched geosynthetic clay liners (GCLs) overlap seams over a range of gravimetric moisture content, including the effect of vertical stress and unevenness of the overlaps. The gas permeability of the GCL overlapped seams was higher than that of intact GCLs, …
