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 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:Civil Engineering Materials.
Civil Engineering Materials. e Material saturated with water, and then dry the surface, is the hole filled with water or closed hole filled with water? What is the condition of putting the material in a jar filled with water? Not to say that the closed hole is not water?
Q:Civil engineering expertise which to master the technology (specific point of speaking)
Civil engineering is the construction of various types of engineering facilities of science and technology collectively. It refers to the technical activities of the materials, equipment and facilities carried out by survey, design, construction, maintenance and repair; also refers to the object of construction, that is built on the ground or underground, land or water, directly or indirectly for human life Construction, military, scientific research services such as housing, roads, railways, transport pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage and protection works The material basis of the facility is land, building materials, construction equipment and construction machinery. With these material conditions, economic and convenient to build both to meet people's requirements and aesthetic requirements, but also safe to withstand the load of various engineering facilities, civil engineering disciplines is the starting point and destination
Q:Civil Engineering Materials Laboratory electricity about how much watts
This is hard to say, the laboratory equipment to ask the owners to know the electricity
Q:What are the raw materials for civil engineering?
There are three large series of buildings, civil, electrical, plumbing, civil steel reinforced concrete, is called 3 large, masonry, commodity concrete, turnover, waterproof, paint, flooring, small materials
Q:Material in the role of civil engineering in which should be the main understanding
From the construction materials used in the construction site and the role of materials and performance requirements to understand
Q:Seeking 3500 words civil engineering materials, urgent use
This paper from the construction site engineering materials management, targeted to explore the means of engineering materials management methods, the use of value engineering theory on the bulk of the turnover of materials (such as the construction of materials, materials, materials, materials, The contents, methods and influencing factors of engineering materials management are introduced and analyzed from different angles, which is of great significance to improve the level management of civil engineering materials.
Q:Detailed classification of civil works?
Civil engineering is generally divided into civil engineering, geotechnical professional, water supply and drainage professional. Different schools will have their own different professional classification.
Q:The gap between China 's civil engineering building materials and abroad
If there is a gap, I think the most fundamental gap lies in its own positioning and positioning of their own direction of it. Affect the norm of the most fundamental or money, how much money to do many things, the standard to improve the money or do the same bad, regulate this thing itself is the result of multi-party game
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.
