INTRODUCTION

Geosynthetic Clay Liners (GCLs) are geotextile and bentonite composites (typically sodium bentonite sandwiched between two layers of geotextile) engineered for a variety of environmental containment applications. The geotextiles offer a long lasting resistance to physical or chemical break-down in harsh elements, while the bentonite’s high swelling capacity and low permeability provide an effective hydraulic seal.

GCLs provide an excellent alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. Benefits include easy installation, better hydraulic performance and resistance to varying weather conditions. Installation for most GCL projects can be completed by construction personnel using conventional equipment. GCLs also have unique self-sealing attributes, reducing the risk of failure due to adverse field and operating conditions.

TYPICAL LINING APPLICATIONS INCLUDE:

  • Canals, stormwater impoundments and wetlands
  • Secondary containment
  • Highway and civil
  • Landfill liners
  • Landfill caps
  • Mining
  • Ponds

DETOURS GOLD GCL'S INSTALLATION

Detour Lake Gold Mine, an open pit mine in northern Ontario, commenced gold production in 2013. With an expected mine life of about 22 years, water needs to be constantly removed from the mine site in order to keep mining operations running…
