Product Description:

GCL(Geocomposite Geosynthetic Clay Liner)

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 non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).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.

1) Environment friendly. Liu Fangzi GCL is made of natural raw materials of sodium bentonite. Aging and corrosion never 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. Natural sodium bentonite has been formed for billions of years.Its waterproof properties are much longer 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 use. 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 has been 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’s 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.

Q:What are the types and properties of commonly used civil engineering materials?
Generally classify the various classification methods by appropriate combination of materials after the division. Such as decorative mortar, asphalt waterproof material.
Q:Why civil engineering materials are important
Look at the current international and domestic trends to compare these three kinds of materials, while the performance of the material itself is to limit the application of its factors.
Q:Discussion on the importance of materials in civil engineering
On the structure, the construction, the project quality have an impact
Q:Why civil engineering to solve the problem is to give full play to the role of materials
Material compatibility issues. We all know that the football team has played well, not to the best players in a certain area together, but to cooperate with each other well. The same is true between the different materials.
Q:Vehicle engineering civil engineering machinery engineering and automation materials which is better Ah are doing
1. Mechanical Engineering and Automation 2. Civil Engineering 3. Vehicle Engineering 4. Materials Science
Q:Civil Engineering Materials
The autoclaved aerated concrete block out of a week after the masonry, GB50203-2017,6.1.3, block age shall not be less than 28 days. Mainly consider the lack of age, is likely to shrink, causing cracks.
Q:Detailed classification of civil works?
According to its use: can be divided into structural materials, decorative materials, waterproof materials, insulation materials, etc .; according to its function: can be divided into structural materials, decorative materials, waterproof materials,
Q:Civil engineering materials on the prospects for talent employment, a little more
The key is to see what you are interested in what the current development of the chef industry quite good, chef technology to worry about can not find a job, when not you find a job but work to find you, learn professional chef technology to choose Professional schools, mainly to see their teaching quality and campus environment.
Q:The gap between China 's civil engineering building materials and abroad
I think the attitude of the subject can explain the most fundamental gap - the positioning of their own position and their own development of the positioning of many high-rise building, the world's top 100 high-rise buildings in China nearly half, and many very high degree of public construction. Feel the 1950s norms copy the Soviet Union until now, the basic theoretical framework has not changed, the relative development of disciplines, the relative cutting-edge areas may be the direction of the material, have nothing to do with the professional relationship. Domestic understanding is often even narrow to the same as the building structure of the project, the subject is so understanding, this is not wrong, but our time on the demand for civil resources in this only, does not mean that civil engineering itself.
Q:Civil engineering materials what is the toughness of the material
The inherent nature of the material varies depending on the material
