Product Name: Geomembrane composites
Characteristics of Geomembrane composites:
Geomembrane composites is of Geosynthetics, this complex anti seepage material is composed of geotextile and geomembrane by the method of heat bonding,there are long fiber Geomembrane composites and short fiber Geomembrane composites. Long fiber Geomembrane composites is composed of continuous filament needle punched geotextile and geomembrane. Short fiber Geomembrane composites is composed of stable fiber geotextile and geomembrane. It functions as anti-seepage, reinforcement, protection, separation and horizontal drain when used in project Moreover; this material shortens the time limit for projects and reduces the engineering cost.
Applications of Geomembrane composites:
In geotechnical engineering, Geomembrane composites mainly functions as anti-seepage and separation. Meanwhile, reinforcement and protection emerge together. It funtions as anti-seepage in projects such as earth rock fill dam, rock fill dam, masonry dam, concrete dam, sewage dam, and, channel ,reservoir, subway basement ,tunnel, road, railway, groundwork, etc.
