                                       sodium Bentonite Geosynthetic Clay Liner(GCL)

 

1,Introduction

 

bentonite geotextile clayliner is composed of 3 levels. The upper level and the lower level are woven geotextile  and non woven textile. 

The middle level is bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. 

The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. 

 

2,Feature

(1) A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s. Because the Department of Natural sodium bentonite inorganic materials, even after a long time or the surrounding environment changes, aging or corrosion does not occur.

 

(2) Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction. Just when construction GCL waterproof blanket tile on the floor, when the elevation or slope construction, with nails and washers to secure it, as required, can overlap.

 

(3) Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.

 

(4)green: Bentonite is a natural inorganic material, harmless, non-toxic, no particular impact on the environment, with good environmental performance.


(5) simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste. Product width up to 6 meters, with international geotextile (film) to match the size, greatly improving the efficiency of construction.

 

(6) Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.

Q: What are the advantages of using geomembranes for secondary containment?
There are several advantages of using geomembranes for secondary containment. Firstly, geomembranes are highly durable and resistant to punctures, tears, and chemicals, ensuring a reliable barrier against leaks or spills. Secondly, they can be custom-designed to fit any shape or size of containment area, providing flexibility and versatility in their application. Additionally, geomembranes are relatively easy to install and maintain, saving time and costs compared to traditional containment methods. Lastly, they are environmentally friendly as they prevent the contamination of soil and groundwater, protecting the surrounding ecosystem.
Q: How do geotextile tubes help in coastal erosion control?
Geotextile tubes, also known as geotubes, play a crucial role in coastal erosion control by acting as a barrier between the land and the water. These large fabric tubes are filled with sand or sediment and placed along the shoreline to create a protective barrier against waves, tides, and currents. The geotextile fabric allows water to pass through while retaining the sediment, which helps to build up the beach and prevent further erosion. Additionally, the tubes can be arranged in various configurations to redirect the flow of water and reduce its erosive power.
Q: Are there any earthwork products specifically designed for agricultural projects?
Yes, there are several earthwork products specifically designed for agricultural projects. Some common examples include drainage tiles, erosion control blankets, silt fences, and contour plowing techniques. These products and techniques help improve soil health, prevent erosion, manage water flow, and enhance overall agricultural productivity.
Q: Are earthwork products resistant to pests and insects?
Yes, earthwork products are typically resistant to pests and insects due to their natural composition and lack of organic matter.
Q: How do geosynthetic clay liners aid in environmental protection?
Geosynthetic clay liners (GCLs) aid in environmental protection by providing a highly effective barrier against the migration of pollutants. These liners are designed to prevent the leakage of contaminants, such as hazardous chemicals or landfill leachate, into the surrounding soil and groundwater. GCLs also contribute to the stability of engineered structures, such as landfills or containment ponds, reducing the risk of environmental damage. Additionally, these liners offer excellent hydraulic conductivity, which helps manage stormwater runoff and prevent erosion. Overall, geosynthetic clay liners play a crucial role in safeguarding the environment by preventing contamination and promoting sustainable waste management practices.
Q: What are the benefits of using geocells in pavement applications?
There are several benefits of using geocells in pavement applications. Firstly, geocells provide increased load-bearing capacity, which helps to distribute the weight of vehicles more effectively and reduce the risk of pavement failure. Secondly, geocells improve the overall stability of the pavement by preventing lateral movement of the fill material. This helps to reduce rutting, cracking, and other forms of pavement distress. Additionally, geocells enhance the drainage capabilities of the pavement, allowing for efficient water infiltration and reducing the potential for water-related damage. Lastly, geocells are easy to install, cost-effective, and environmentally friendly, making them a sustainable solution for pavement construction and maintenance.
Q: How do geopipes help in stormwater infiltration systems?
Geopipes help in stormwater infiltration systems by efficiently channeling and distributing stormwater runoff underground, allowing it to percolate into the soil and recharge groundwater. They provide a controlled flow pathway, preventing erosion and evenly distributing the water for optimal infiltration.
Q: What are the benefits of using geosynthetic panels in slope stabilization?
The use of geosynthetic panels in slope stabilization offers several benefits. Firstly, these panels provide an effective barrier against erosion, preventing soil movement and reducing the risk of landslides. Secondly, they enhance the stability of slopes by distributing the loads evenly, thereby minimizing the potential for slope failure. Additionally, geosynthetic panels are quick and easy to install, saving time and labor costs. They are also cost-effective compared to traditional methods of slope stabilization. Lastly, these panels are durable and resistant to environmental conditions, ensuring long-term effectiveness in slope stabilization projects.
Q: Can geopipes be used for drainage systems?
Yes, geopipes can be used for drainage systems. Geopipes are specifically designed to efficiently drain and transport water, making them an effective solution for drainage systems in various applications, including roads, sports fields, and agricultural areas. They are durable, lightweight, and have high flow capacity, making them an ideal choice for managing water runoff and preventing flooding.
Q: Are earthwork products suitable for both residential and commercial projects?
Yes, earthwork products are suitable for both residential and commercial projects. Earthwork products such as gravel, soil, and aggregates can be used in various construction applications in both residential and commercial settings. These materials are commonly used for building foundations, landscaping, road construction, and other construction projects, regardless of the project's scale or purpose.
