Customized Request Accept Bentonite Geosynthetic Clay Liner For Various Applications
Product Introduction
Sodium bentonite waterproof blanket (GCL) is a new type of environmental protection and ecological composite impermeable material, which is widely used in water conservancy, environmental protection, transportation, railway, civil aviation and other civil engineering. Its main components are graded natural sodium bentonite particles and corresponding admixtures, and the bentonite particles are fixed between geotextile and plastic woven cloth by needling process.
Product Properties
Sodium bentonite has the property of swelling in contact with water, forming a highly dense gel, so as to achieve excellent anti-seepage effect. This material not only has the sealing, isolation and strengthening effect of geomaterials, but also has the characteristics of strong self-healing, easy construction and good durability.
Product Application
The application field of sodium bentonite waterproof blanket is very wide, including landfill, artificial lake, reservoir, channel, river, roof garden, basement, subway, tunnel, underground passage and other projects that need seepage prevention.
