Description:
Geosynthetic Clay Liner also calls bentonite waterproof blanket, which is a new type of environmental protection composite waterproof and impermeable material. Geosynthetic Clay Liner fills the bentonite particles between the woven geotextiles and the non-woven geotextiles, and combines the upper nonwoven fibers through the bentonite particles, through special technology and equipment. At the same time, according to the requirements of the project, a layer of HDPE film (high density polyethylene film) can be bonded on the waterproof blanket to adapt to the laying of special environment, so as to achieve dual waterproof and seepage-proof effect.
Product Features:
The permanent waterproof Because sodium base bentonite is a natural inorganic material, even after a long time or the surroundin g environment changes, also won't happen aging or corrosion phenomena, so the waterproof performa nce persistence.
Not affected by temperature In cold climates will not brittle fracture.
Environmental protection Bentonite as natural inorganic material, non—toxic harmless to human body, no special effects to the environment, It has good environmental performance.
Simple and short time of construction

Application:
Geosynthetic Clay Liner can be widely used in municipal, highway, railway, water conservancy.
environmental protection and underground waterproof engineering in industrial and civil buildings. Anti-seepage engineering of landfill liner system, reservoir and diversion canal.
It is suitable for external waterproofing of various underground structures and underground buildings, and can replace cement mortar waterproofing layer, paint waterproofing layer and other waterproofing layers in underground engineering waterproofing.
