BENTOLINER^® NW is a needlepunched reinforced composite geosynthetic clay liner (GCL) comprised of a uniform layer of granular sodium bentonite encapsulated between a nonwoven and a scrim-nonwoven geotextile for dimensional stability. The product is intended for moderate to steep slopes and moderate to high load applications where increased internal shear strength is required.

Key points:

• 

  Engineered for moderate to steep slopes and moderate to high load applications. 

• 

  Double nonwoven GCL provides increased shear performance. 

• 

  Combines the dimensional stability and increased internal shear strength of reinforced geotextiles with the high swelling capacity and low permeability of sodium bentonite.

• 

  Provides high sealing effect and outstanding mechanical properties.

• 

  Provides better hydraulic properties compared to compacted clay.

• 

  More cost effective than compacted clay.
