Eurobent - Geosynthetic Clay Bentonite Liner (GCL)
Eurobent GCLis an extremely versatile product. It is a combination of two or more layers of geotextile and bentonite, a clay material with excellent swelling ability. This combination of bentonite, woven and non-woven geotextiles ultimately made it possible to produce a reinforced, strong sealing layer.
Eurobent GCL provides a reliable barrier to liquids, steam and gases. It ensures the highest standards of safety and profitability. The excellent absorption and swelling properties of bentonite result in extremely low permeability of our GCL.
The reasons that you should choose the EUROBENT solution:
- a state-of-the-art natural sealant available on the market,
- replaces the need to use traditional mineral sealants, especially compacted clay,
- offers better sealing performance than conventional materials,
- Solution security: Due to the swelling properties of bentonite, GCL is able to repair itself in case of small perforations in geotextile layers. The certified quality of our product enhances on-site construction safety.
- The flexibility of solutions: We offer very flexible solutions, each time tailored to the client`s needs. Our bentonite mats are characterized by a large number of possible width and length choices while minimizing the number of connections.
- Minimizing costs: Our bentonite mat provides significant economic benefits. Its low weight decreases transportation costs. The speed and ease of installation do not require highly-qualified personnel, expensive welding or the use of heavy equipment. GCL is simply unrolled on-site and overlapped at the joints.
- Ecology: Eurobent GCL mat is an environmentally friendly product, ISO 14000 certified.
The production technology requires a combination of two separate synthetic fabrics that detach the bentonite layer. The final effect is obtained by putting the loose bentonite granules between the PP nonwoven layer and the PP woven layer. Strong connection of all layers is given by a special method of joining, called needle-punching. It involves pulling the fibres from nonwoven layer through bentonite layer and fixing them on the outer surface of woven layer. Thanks to this process all layers are properly combined and remain flexible.
