Sanderay Geosynthetic clay liner-RNP

Sanderay^®GCL-RNP, Which is four layer GCL, The carrier layer is used woven and nonwoven composite fabric to replace single woven carrier(Figure 3.3). This type GCL would reinforce internal shear strength, which could be used in steep slope greater than 1V:3H, and made the waterproof layer structure more stable. The bentonite couldn’t flee from the sandwich structure in GCL hydrated situation
