Brief Introduction

Geosynthetic clay liner-GCL is a new type of waterproofing material geosynthetics. It is made of natural Naji bentonite granule and corresponding admixture by special technique and equipment. Through mix them evenly, the thousands of hi-strength fibers form a strong force, which fix the hi-expansibility Naji bentonite tightly between the two layers of geotextiles. GCL has the function of sealing, isolation and reinforcement
