GCL Composite Vertical Anti-seepage Barrier
   GCL Composite Vertical Anti-seepage Barrier  is an innovative composite vertical anti-seepage system which  combines GCL with conventional vertical cut-off wall.
 1.  Characteristics:

  • Introduce GCL into vertical anti-seepage, permeability≤1*10-7cm/s, in line with environmental protection  requirements.

  • Settle some defects of conventional  cut-off wall, such as low permeability level, poor  chemical compatibility and great difficulty in construction.

  • Composite structures  can cope with more complex projects.

  • Mechanized  construction, high construction quality and high construction efficiency.

2.  Scope of Application:
   Can be  applied to slotted vertical cut-off walls.
   It is  especially suitable for the vertical anti-seepage field with high anti-seepage  requirements such as pollution site repair, landfill, old simple landfill  reconstruction and tailings dam.
