GEOBENT is a geocomposite consisting of natural sodium bentonite. The bentonite is encapsulated between two geotextiles, one woven and the other non-woven. All components are securely bonded through the needle-punching process, providing the final product with robustness and a high safety margin in slope installations. Geotesan Geobent AS 3500 is manufactured under rigorous quality controls, meeting the highest international standards. 

This geocomposite serves various purposes, especially in slope stabilization projects. The woven and non-woven geotextiles enhance the overall strength of the product, ensuring durability and reliability in challenging terrains. The encapsulated sodium bentonite further contributes to its effectiveness in applications where fluid barriers or environmental sealing is required.
