Lining Systems

Bentofix Thermal Lock Geosynthetic Clay Liners are needle punched reinforced composites which combine two durable geotextile outer layers and a uniform core of high swelling powder sodium bentonite clay to form a hydraulic barrier. When hydrated with fresh water the bentonite swells to form a low permeability layer with the equivalent hydraulic protection of a thick compacted clay layer.

  • Quick and easy to install
  • Wide 4.85m rolls make installation easier
  • Self sealing overlaps
  • Thermal lock process increases internal shear strength and interface friction angles
  • Can reduce costs by replacing thick clay layers

Withstands differential settlement Carbofol® Geomembranes are manufactured using high density polyethylene (HDPE). Carbofol® is produced in various thicknesses and with smooth or embossed
structured surfaces. Carbofol® geomembranes provide a complete seal against even the most toxic substances. Carbofol® is typically used in sealing applications for landfill base seals as well as caps, in environmental sealing applications for the protection of groundwater from contamination and in water conveyance structures, canals or ponds.
