clay liner

Ramina designs and manufactures complete Geosynthetics clay liner lines for the production of bentonite geocomposites. Bentonite clay is a low-permeability material, and it is contained between two PP Geotextiles (one upper needled nonwoven geotextile layer and one lower woven geotextile layer). The GCL line allows the formation of geocomposite through a mechanical fixing, needling the three layers together. The result is a flexible, versatile and resistant material that can be used to create a hydraulic barrier in a wide range of areas, especially in landfill sealing and civil engineering applications.
