4000GSM Geosynthetic Clay Liner 3 Layer Bentonite Waterproof
Blanket Eco - Friendly
Geosynthetic clay liners (GCLs) Description:
Geosynthetic clay liners (GCLs) are high performance needle punched environmental reinforced
composites which combine two durable geotextile outer layers with a
uniform core of natural
sodium bentonite clay to form a hydraulic barrier. Fibers from the
nonwoven geotextile are needle punched through the layer of
bentonite and incorporated into the other geotextile
(either a woven or nonwoven).when hydrated under a confining load,
the bentonite swells to
form a low permeability clay layer with the equivalent hydraulic
protection of several feet of compacted clay.
Geosynthetic clay liners (GCLs) 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.
5. Disposal of subgrades:
1. the subgrades must be tamped before paving the GCLs, the surface
should be smooth. And it should not
have the obvious hollow space.
2. the surface should be dry.
3. the minimum angle of land surface exposed to the sun should be
more than 30cm.
4. the construction of GCLs should be begin until checking out the
foundation
6. Preparation before paving the GCLs
