Introducing the ultimate solution in geosynthetic innovation: the Geosynthetic Clay Liner (GCL). This advanced product is crafted through the meticulous integration of sodium base bentonite, recognized for its exceptional swelling capabilities, nestled between a unique composite geotextile and nonwoven fabric. Seamlessly assembled via needle punching or stitching, this impervious marvel forms a multitude of micro-fiber spaces, effectively immobilizing bentonite particles to avert unilateral flow. When exposed to moisture, the mat transforms into a uniformly dense colloidal layer, ensuring watertight integrity and preventing any leakage. Ideal for varying project requirements, the GCL can be expertly paired with an HDPE liner to enhance its waterproof efficacy. Unlike general calcium bentonite, which expands to merely three times its size, sodium base bentonite, when hydrated, can absorb up to five times its weight in water, expanding its volume 15 to 17 times its original size. The geotextile and nonwoven components securely encase the bentonite, providing reinforcement and safeguarding the integrity of the GCL, which boasts commendable shear strength.
