Product Description:

Geocomposite Geosynthetic Clay Liner/GCL

 

 

Introduction:

 


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 is the civil engineering material
Do something about the civil material
Q:What are the major civil engineering courses?
Steel structure design principle "" high-rise building structural design "" engineering geology "" engineering structure earthquake "" concrete and masonry structure "" concrete structure design principle "" basic engineering "
Q:What is the course of civil engineering materials?
Wood and wood materials, such as gypsum lime cement and concrete reinforced concrete, etc.
Q:Now undergraduate civil engineering, what courses, which textbooks?
Main courses: engineering mechanics, fluid mechanics, rock mechanics, foundation and foundation, engineering geology, engineering hydrology, engineering drawing, computer application, building materials, concrete structure, steel structure, engineering structure, water supply and drainage engineering, construction technology and management
Q:What are the three categories of civil engineering materials classified according to the basic composition?
According to the material is divided into inorganic materials, organic materials, composite materials, metal materials.
Q:Civil engineering, machinery, materials and finance which relatively good employment?
Of course, is the civil ah I give you analysis of the material of the wide range of professional employment, but the depth is not enough wages ah what is not ideal employment rate is not too high (I am the material you do not be his name scared) unless you are Submit the material of the professional or you decide to study the future
Q:What are the three mechanics of civil engineering?
Civil engineering is the planning, construction and maintenance of everything related to water, soil and culture. At present, general civil works include roads, water conservancy, drainage, disaster prevention and transportation. In the past, all non-military civilian projects were classified into this class. However, as engineering science became more and more extensive, many of the original contents of civil engineering had become independent.
Q:Are building materials the same as civil engineering materials?
Civil engineering includes a wide range of materials, except for buildings, roads, bridges, tunnels and geotechnical materials that are related to civil engineering materials, but many of these materials are not used in industrial and civil construction.
Q:What is the meaning of the wetting angle in civil engineering materials?
English name: wetting angle Definition: liquid and solid phase contact point at the liquid-solid interface and liquid surface tangent angle.
Q:Material science and civil engineering which is better?
Definitely civil engineering is good
