Advanced geosynthetic clay liners (GCLs)
Geosynthetic clay liners with self-sealing edges (ss)
Description: this GCL has special self-sealing edges. They are made under workshop conditions by even application of bentonite powder to longitudinal sides of the clay liner. The application width equals the size required for overlapping when laying. This technology allows even application and reliable fixation of bentonite powder on the fabric and prevents peeling and early hydration.
The material is produced according to standard STO 87299967.003-2022 rolled geosynthetic bentonite materials BentIzol. Technical Specifications and STO 87299967.004-2021 “MASTERBENT rolled geosynthetic bentonite materials. Technical Specifications”.
Advantages: Self-sealing edges of GCL allow for a significant acceleration of laying, as there is no need to cover the seams with granules. Increased reliability of seams sealing.
Reinforced geosynthetic clay liners (F)
Description: this GCL is supplemented with a layer of woven or non-woven geotextile, or their combination to increase mechanical strength.
The material is produced in accordance with standard STO 87299967.003-2022 “Bentonite roll geosynthetic materials BentIzol. Technical conditions” and STO 87299967.004-2021 “MASTERBENT rolled geosynthetic bentonite materials. Technical conditions”.
Advantages: increased mechanical strength and load-bearing capacity compared to a standard GCL.
Geosynthetic clay liner with geomembrane “under welding”
Description: This GCL is supplemented with geomembrane ‘under welding’ with thickness of 0.8 mm and more, depending on the customer’s needs. The material is produced in accordance with the standard STO 87299967.003-2022 “Bentonite roll geosynthetic materials “BentIzol”. Technical conditions” and STO 87299967.004-2021 “MASTERBENT rolled geosynthetic bentonite materials. Technical conditions”.
Advantages:
- Reliable double screen: in case of damage to the geomembrane layer, the bentonitic mat takes over the protection of the object.
- Quick to lay compared to laying materials separately.
