bentonite waterproof blanket (GCL) is earthwork composite material that is specially used for anti-seepage of man-made lake waterscape, landfill yard, underground garage, building roof garden, water tank, oil depot and chemical pile yard
What is bentonite waterproof blanket (GCL) ?
bentonite waterproof blanket (GCL) that is produced by filling sodium base bentonite with high expansion between special composite earthwork cloth and non-woven cloth and locking bentonite on lower composite fabric through upper non-woven cloth fabric by special needle embroidering method. Bentonite anti-seepage liner produced by needle embroidering method can form many small fiber spaces, which prevent bentonite particles from moving in one direction, rubber head water layer with uniform high density is formed in the liner when meeting water so as to prevent water seepage effectively.
bentonite waterproof blanket (GCL) application
bentonite waterproof blanket (GCL) is mainly used in various environmental protection projects such as waste landfill yard, underground reservoir and underground infrastructure, solves sealing, isolation and anti-seepage problems, and has good effect and strong damage resistance
bentonite waterproof blanket (GCL) Features:
1. Environment friendly
It is raw and natural materials,;aging and corrosion seldom happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good
ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural,
new, green waterproof material.
2. Permanent waterproof, excellent performance
Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform
to high density septum under hydro pressure. When The thickness is 3mm, the permeability is below a*10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention
performance is evident.
3. Easy to construct
Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained
by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on
overlap point. When water comes, GCL would be overlapped automatically. It is so far the only material that
starts the waterproof effect by water in the world. It is not necessary to take additional examination when the
construction is completed. The repair works are easy in case of waterproof defects. Among the existing
waterproof materials, GCLs construction period is the shortest and its operation is the easiest. It has an
eminent effect on shortening the construction period as well as saving the cost.
4. Strong Self-Restore Capacity
The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even
if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on
the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be
finished within 15 days completely.
