About US

This is us

It was formed millions of years ago through the aqueous deposition of volcanic ash.

GCL Applications:

  • Over 200 million square metres have been installed Europe wide in the last 10 years
  • Where? 
  • Ponds (stormwater, municipal and industrial wastewater, coal combustion wastes, agricultural waste, etc.)
  • Landfills (bottom liners and final covers)
  • Secondary containment
  • Wetlands
  • Engineered remedial barriers
  • Mining (heap leach pads, tailings impoundments)

a bit about our ponds

Speed/Ease of Installation

  • Typical GCL installation rates of 1 to 2 acres per day for a five-man crew, with limited heavy machinery
  • Typical 2-ft thick compacted clay liner installation rates vary widely, typically no more than 1 acre per day with typical equipment consisting of excavator, compactor, bulldozer, water truck
  • GCLs offer a preferable working surface for deploying and welding the overlying geomembrane
  • Less truck traffic, safer operations
  • Shorter construction schedule
  • Airspace
  • GCLs take up less volume in landfill, allowing more room for waste (1 cm versus 0.6 or 1 m)

bentoknight

“Bentoknight” is a Bentonite Clay Liner made up of sodium bentonite clay held together in a sandwich of non-woven and woven geotextiles. When hydrated, unconfined bentonite can swell to 15 times its dry value and can self-heal when punctured making this a fantastic choice for a long lasting solution which does not require specialist welding.

Why is Bentoknight a good liner material?

  • It swells when hydrated
  • Bentonite swells up to 15 times its original volume if unconfined.
  • Bentonite expands and conforms to irregular surfaces, penetrations, and infiltrates cracks and voids.
