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.

Specification:

 


Mass per unit ≥ 4000g / m²

Width: 4-6 m 

 Size: 5.8 x 30m , or customized 

 bentonite sandwiched between two layers of geotextile

 
Features: 


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 classification of civil engineering graduate students?
Major professional basic courses and specialized courses / structural engineering, engineering mechanics and water conservancy projects
Q:Civil engineering and new materials, which is a good job
Obviously civil, our school is now the situation is graduated in 2017, the civil has been signed, the work tube has not yet begun. Said the prospects of the big tube, a little self-deception, civil construction of the size of the project manager is the vast majority of civil origin, the number of project managers can be ignored, the construction company executives are mostly civil, budget origin. To say that the real estate management of the dominant, just a little funny, real estate is simply not willing to go to the civil, to learn nothing, grow very slowly, most people are more willing to do a few years in the construction unit to go to real estate, Then much more understanding, the growth rate is much stronger than the tube. Since you have learned the civil estimate you know some, if you are a boy, not the kind of people who can not eat a bit bitter, it is recommended not to turn the work tube, the other pipe is relatively simple, the management of things want to learn to get started And soon, if necessary, can work to learn. Of course, the benefits of the work tube, graduated from the management of the degree, but like the general school of this degree of gold can not agree with the degree.
Q:What are the basic properties of civil engineering materials?
The basic nature of the material refers to the most basic and common nature that must be considered in civil engineering. The special nature of the material refers to the nature of the material itself, which is different from the material of other materials. It is the embodiment of the specific use of the material.
Q:Material in the civil engineering in what kind of position
You said that material important is not important. It can be said that the material is the cornerstone of civil engineering. No material what is the air castle.
Q:Read materials science and engineering or civil engineering, it is tangled ah, we discuss together!
If you consider employment, or read civil, if you want to do some academic, or read the material, rough for reference only.
Q:Civil engineering materials in the two grinding a burning what does this mean
Refers to the cement material, cement is the first stone and other raw materials, grinding, and then after high temperature calcination, and then after grinding into powder
Q:What is civil engineering and architecture?
Two professional comparison in the design industry is most obvious, is two professional called architecture and structural professional. The former concept of the program, consider the function and layout, which consider the internal reinforcement and other structural problems, to achieve the former concept, both with water, warm, electricity professional to complete a project design.
Q:What are the four major mechanics in civil engineering?
You should not be civil engineering, engineering mechanics contains the theory, materials, structural mechanics knowledge, agreed to theoretical mechanics, material mechanics, structural mechanics, soil mechanics for the four major civil mechanics
Q:Material in the role of civil engineering in which should be the main understanding
1, the material workers need to understand the construction process planning materials, and in accordance with the plan to organize materials approach. 2, in the approach materials, material staff should be responsible for the quality, good tracking service. Master the use of materials. 3, for the entry of materials into the field, the need for materials according to the nature of materials to tak
Q:What are the civil engineering materials?
Inorganic cement, cement, concrete, mortar, steel, masonry, wood, synthetic polymer, waterproof material, decorative materials.
