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.

3,Application

(1)Municipal engineering, underground engineering subways, buildings and roofs reservoir seepage.

(2)Environmental sanitation, solid waste landfills, sewage treatment plants, industrial waste.

(3)water, rivers, lakes and reservoirs dam seepage, plugging, reinforcement.

(4)Garden artificial lake golf course pond seepage and so on.

(5)Petrochemical, mining and other areas of engineering seepage, leakage, etc.

Q: How do earthwork products contribute to soil stabilization in construction sites?: Earthwork products, such as geotextiles, geogrids, and geomembranes, play a crucial role in soil stabilization on construction sites. These materials are designed to enhance the soil's strength, prevent erosion, and control water movement, ensuring the stability and durability of the built structures. Geotextiles, for example, act as filters, separating different soil layers, preventing intermixing, and reinforcing the soil. Geogrids, on the other hand, provide tensile strength to the soil, increasing its load-bearing capacity and reducing settlement. Overall, earthwork products improve the overall stability of the soil, minimize the risk of slope failure, and contribute to the long-term success of construction projects.

Q: How do geosynthetic clay liners prevent leakage in landfill caps?: Geosynthetic clay liners prevent leakage in landfill caps by acting as a barrier that restricts the movement of liquids. These liners are made up of a layer of bentonite clay sandwiched between two geotextile layers. The bentonite clay swells when it comes into contact with water, creating a dense and impermeable layer. This swelling property of the clay helps to seal any potential gaps or cracks in the landfill cap, preventing the leakage of liquids such as leachate into the surrounding environment.

Q: How do geosynthetic clay liners work in landfill projects?: Geosynthetic clay liners (GCLs) are used in landfill projects as a barrier system to prevent the migration of leachate, which is the liquid generated from the decomposition of waste, into the surrounding environment. GCLs consist of a layer of bentonite clay sandwiched between two geotextile layers. When hydrated, the bentonite clay expands, creating a low-permeability barrier that effectively seals the landfill. This prevents leachate from escaping and contaminating nearby soil and groundwater. Additionally, the geotextile layers provide added strength and stability to the liner system. Overall, GCLs play a crucial role in landfill projects by enhancing environmental protection and ensuring the safe containment of waste.

Q: How are earthwork products manufactured?: Earthwork products are typically manufactured through a two-step process. Firstly, the raw materials, such as soil, clay, or gravel, are excavated or sourced from quarries. These materials are then processed, often through crushing, screening, and mixing, to achieve the desired consistency and quality. Secondly, the processed materials are molded or shaped into specific forms, such as bricks, blocks, or panels, using various techniques like compression, extrusion, or vibration. These manufactured earthwork products are then cured or dried before being ready for use in construction projects.

Q: What are the different surface patterns available in earthwork products?: There are various surface patterns available in earthwork products, including smooth, textured, stamped, and exposed aggregate finishes. Smooth surfaces provide a sleek and polished look, while textured patterns offer a more rugged and natural appearance. Stamped patterns allow for intricate designs and imitate the look of various materials like brick or stone. Exposed aggregate surfaces showcase the natural beauty of the aggregates used in the concrete mix. These different surface patterns provide options for customization and can enhance the aesthetic appeal of earthwork products.

Q: What are the requirements for civil engineering materials?: I think it's a requirement. The The Product to be qualified

Q: Can geosynthetics be used to stabilize slopes?: Yes, geosynthetics can be used to stabilize slopes. Geosynthetics such as geotextiles, geogrids, and geocells are commonly used in slope stabilization projects. These materials can provide reinforcement, erosion control, and drainage solutions, thereby enhancing the stability and long-term performance of slopes.

Q: What are the advantages of using geosynthetic liners in secondary containment systems?: Geosynthetic liners offer several advantages in secondary containment systems. Firstly, they provide an impermeable barrier, preventing the leakage of hazardous substances into the environment. This helps in protecting soil and groundwater from contamination. Secondly, geosynthetic liners are highly flexible and can conform to different shapes and sizes, making them suitable for various containment applications. Additionally, these liners are resistant to chemical degradation, UV radiation, and mechanical stress, ensuring their long-term durability. Moreover, they are easy to install and require minimal maintenance, resulting in cost and time savings. Overall, geosynthetic liners enhance the effectiveness and reliability of secondary containment systems, promoting environmental safety and compliance.

Q: Can earthwork products be used in road construction?: Yes, earthwork products can be used in road construction. Earthwork products such as soil, gravel, and stones are commonly used as base materials and fillers in road construction projects. These materials are compacted and layered to create a stable foundation and provide drainage for the road surface. Additionally, earthwork products can be used for embankments, slopes, and other structural components of the road.

Q: Are earthwork products suitable for use in underground drainage systems?: Yes, earthwork products can be suitable for use in underground drainage systems. Earthwork products, such as geotextiles and geocomposites, are commonly used in underground drainage systems to provide filtration, separation, and reinforcement. These products help prevent soil erosion, filter out fine particles, and improve the overall performance and durability of the drainage system.
