Revestimiento de Arcilla Geosintética(GCL)

Los Revestimientos de Arcilla Geosintética (GCL) OSO, también denominados tapetes de bentonita, son geocompuestos reforzados que consisten en una capa de gránulo de bentonita sódica fijada mediante punzonado a un geotextil tejido y un geotextil no tejido. Los productos se utilizan como barrera contra líquidos y gases en una amplia variedad de aplicaciones civiles, geotécnicas, ambientales e hidráulicas.
