Products Description

Earthwork Essential 15mm Thick Swelling Seal Sodium Bentonite Mat for Landfill Liners

BENTONITE GEOTEXTILE

It is composed of 3 levels. The upper level and the lower level are woven geotextile and non woven textile. The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special

processing. The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects.
GCL can be applied separately, or combined with high density polyethylene (HDPE).
Our GCL combines the two advantages together, not only containing all the properties of geotextile materials, but also bearing of double waterproof property.

Product characters

1. Environment friendly
GCL is made of raw materials of sodium-bentonite.
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.

2. Permanent waterproof, excellent performance
Natural sodium bentonite was formed billions of years ago.
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, GCL 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 concretestructure immediately.
Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.

Waterproof mechanism:

Sodium bentonite is non-metallic clay composed mostly of the mineral montmorillonite.
It is formed from volcanic ash and is mined out of Wyoming and South Dakota.
Montmorillonite is a layered clay mineral with broad, flat platelets that are ideally shaped to provide a hydraulic barrier.
Sodium ions located between these platelets allows water to hydrate the bentonite in a remarkable fashion that results in the highswelling characteristic.
Dry sodium bentonite can swell to many times its original volume when exposed to water. Because of its high swelling capability bentonite is able to seal around penetrations, giving geosynthetic clay liners theirself-healing characteristic. A fully hydrated layer of sodium bentonite will result in a hydraulic conductivity of less than 5 x10-9 cm/sec. This is approximately twenty times lower than a typical compacted clay layer.

BENTONITE POWDER OR GRANULARS FOR SEALING

1.Bentonite sealing powder or granulars: It is the identical to the bentonite grain of the GCL used as the lap between GCL. Package: 50kg per woven geotextile bag. Applications:

1.waterproof for rooftop garden,basement and so on; 2.waterproof for underground,railway,city highway,oil drilling and so on; 3.Anti-seepage project of mud and stone reinforce 4.desert and environment improvement,trash stuff zone,artificial lake and artificial sight and so on; 5.reservoir,dam,irrigation channel and so on;
