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.
