Bentizol Geosynthetic Clay Liners

Bentizol Geosynthetic Clay Liners (Bentizol CGLs) are rolled geosynthetic waterproofing materials. They are used in the construction of sealing barriers to protect against various pollutants entry into the soil and groundwater. Designed for facilities with high requirements for environmental safety: landfills for solid municipal, food and radioactive waste, oil and gas facilities, hydraulic structures, in mining and metallurgical industries, etc.

Bentizol CGLs will change your perception of waterproofing!

1. You will get a reliable material with unique qualities:

• CGLs are self-healing. The only waterproofing material that is restoring after cuts or punctures, retaining all its properties.
• Environment friendly thanks to key component – natural bentonite clay, mined at own deposits of our company.
• Have high waterproofing properties: the hydraulic conductivity is less than 1х10^-11 m/s. The material will protect the soil and groundwater from the penetration of contaminants: oil, petroleum products, gasoline, lubricants and other solutions or filtrates.
• Long-term: lifetime is comparable to the lifetime of the facility itself.
• Easy to install: do not require welding seams, attraction of specialized equipment and personnel.
• Durable. Withstand hydrostatic pressure up to 7 atmospheres and the movement of heavy machinery during placing.
• Frost resistant. Used in any hydrogeological conditions and at ambient temperatures in the range from -70 to + 60 °^◦С.
• Retain their waterproofing properties in the finished object in the event of subsidence, punching, seismic movement of the ground and the formation of frost cracks.

2. You will save time and money:

• The volume of work on the foundation preparation and the installation of the sealing barrier is reduced due to the technological nature of the GCL. The speed of the installation on a horizontal surface is up to 10 000 m² per working shift.
• You save on labor costs, because installation without welding is much cheaper.
• With our material, you do not need to wait for spring and summer and waste time: it can be installed in any season at any temperature.
• You save 30% on average of the estimated cost for waterproofing of your facility compared to other materials!

Areas of application of Bentizol GCLs

• Landfills for waste disposal (household, industrial, toxic and radioactive) in new construction and at restoration
• Oil and gas industry: main and infield pipelines, pumping stations, oil storage parks and terminals, oil loading platforms, gas stations, oil sludge barns, gas afterburners, etc.
• Hydraulic structures: irrigation and shipping channels, anti-erosion systems, decorative reservoirs, ponds, fountains, artificial streams; water storages, irrigation and fire reservoirs
• Mining and metallurgy industry and power engineering: heap leach pads, evaporation ponds, tailing dumps, ash dumps
• Agriculture: dung lagoons, greenhouses, animal burial sites.
