Product Details

Waste Landfill Railway Sodium Bentonite waterproof pad GCL

Geosynthetic clay liners (GCLs) combine geosynthetics with sodium bentonite clay to form a highly impermeable barrier that often replaces thick layers of expensive compacted clay.

GCL(geosynthetic clay liner) specifications

What makes HongXiang ® GCL unique among geosynthetic clay liners? Our GCL incorporates a woven geotextile for dimensional stability, and is reinforced for increased internal shear strength.These liners are manufactured using excellent quality raw material in compliance with international quality standards. Our Manufacturing Quality Control and Quality Assurance Program ensures that only the highest quality products represent the Hong Xiang ® name.

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 and saving the cost.

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. It is so far the only material that

starts the waterproof effect by water in the world. . 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

1.drawing the GCLs paving order

2.examining the GCLs appearance quality

3.the construction of GCLs should be processed under the weather with no rain and snow
