GCLs for waterproofing

Since ancient times, man used clay for waterproofing (compacted clay layer). New technologies and the most water-retaining clay - bentonite, made it possible to create a perfect waterproofing material – GCL (geosynthetic clay liners).

GCL consists of three layers: woven and nonwoven geotextile and granular bentonite evenly distributed between them. The layers are needle-punched.

GCL are used as a roll waterproofing material in industrial, civil, transport and hydraulic engineering. In addition, GCL effectively protect the soil and groundwater from the ingress of pollutants, which has found its application in the construction and reclamation of waste landfills, in the oil and gas and mining industries, agriculture, etc.

Advantages of using GCL:

• Possesses self-healing properties after damage (when interacting with water bentonite swells out and turns into water-resistant gel which fills defects and continues to protect the object),
• Frost-resistant: retain their properties up to -70°C
• Long-lasting: service life up to 100 years,
• Easy to install: the canvases overlap without welding
• Resistant to mechanical stress
• Preserve properties in the finished object during seismic movement of the soil and the formation of cracks in the soil,
• Environmentally friendly, thanks to natural bentonite clay, mined in the deposits in the Kurgan region, Khakassia, Azerbaijan.
