geosynthetic clay liner (GCL) for refuse landfill

GCL geosynthetic clay liner GCL

GCL(geosynthetic clay liner)commacted with clay liner, it has the advantages of small size,light weight ,good flexibility and seal, easy for construction suitable for uneven settlement 

Specification.Unit weight ≥ 4000g / m², width of 4-6 m Characteristics : Comacted with clay liner,it has the advantages of small size, light weight, good flexibility and seal, easy      for construction and suitable for uneven settlement. Usage Mainly used in environmental engineering of landfill  emissions, underground reservoirs, underground   infrastructure construction projects, sealing solution,   segregation, anti-leakage, good effect, anti-destructive.
