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 are geosynthetic materials used in mining and oilfield applications?: Geosynthetic materials are extensively used in mining and oilfield applications for various purposes. In mining, these materials are commonly employed for lining tailings storage facilities, heap leach pads, and ponds to prevent seepage and contamination of soil and water sources. They also serve as a barrier to control the movement of fluids and gases in underground mining operations. Additionally, geosynthetics are used in reinforcing mine access roads and stabilizing slopes to enhance safety and reduce erosion. In oilfield applications, these materials are utilized in constructing containment systems for oil and gas storage tanks, as well as lining ponds and impoundments to prevent leakage and protect the environment. They also play a crucial role in reinforcing drilling pads and stabilizing the ground during drilling operations. Overall, geosynthetics contribute significantly to improving the efficiency, sustainability, and environmental performance of mining and oilfield activities.

Q:What are the different types of erosion control products for earthwork?: There are several types of erosion control products for earthwork, including erosion control blankets, sediment control fences, silt fences, straw wattles, erosion control mats, and geotextiles. These products are designed to prevent soil erosion, promote vegetation growth, and control sediment runoff during construction or landscaping projects.

Q:How do geosynthetic clay liners work in landfill projects?: Geosynthetic clay liners (GCLs) are used in landfill projects as a barrier system to contain and prevent the migration of hazardous waste and leachate. GCLs consist of a layer of bentonite clay sandwiched between two geotextiles. The clay acts as a low-permeability material, absorbing and swelling in the presence of water, thereby creating a barrier that restricts the movement of fluids. The geotextiles provide reinforcement and protection to the clay layer. Overall, GCLs work by effectively sealing the landfill cells, reducing the potential for contamination and protecting the surrounding environment.

Q:Can earthwork products be used for creating outdoor meditation spaces?: Yes, earthwork products can be used for creating outdoor meditation spaces. Earthwork products such as natural stones, gravel, sand, and soil can be utilized to design and construct serene and tranquil outdoor spaces for meditation. These materials can be used to create pathways, seating areas, Zen gardens, or even small ponds, enhancing the overall atmosphere of relaxation and peace in an outdoor meditation space.

Q:What are the different types of geocells available in the market?: There are several different types of geocells available in the market, including honeycomb, diamond, and hexagonal cell designs. Each type has its own unique features and benefits, but they all serve the common purpose of providing soil stabilization and erosion control in various applications such as road construction, slope protection, and retaining walls.

Q:What are the benefits of using geopipes in underground drainage systems?: Geopipes offer several benefits in underground drainage systems. Firstly, they are made of high-density polyethylene (HDPE) material, which makes them highly durable and resistant to corrosion and abrasion. This ensures a longer lifespan and reduces the need for frequent maintenance or replacements. Additionally, geopipes have a smooth interior surface that facilitates efficient water flow, preventing clogs and blockages. They are also lightweight, making them easier to handle and install, which saves time and labor costs. Moreover, geopipes are flexible and can adapt to ground movement, reducing the risk of cracking or breaking. Overall, the use of geopipes improves the overall performance and longevity of underground drainage systems.

Q:Are earthwork products suitable for constructing decorative walls?: Yes, earthwork products such as bricks, stones, and soil can be suitable for constructing decorative walls. These materials can be used to create a rustic and natural look, providing a unique and aesthetically pleasing appearance to the walls. Additionally, earthwork products are often durable and long-lasting, making them a practical choice for constructing decorative walls.

Q:Are there any earthwork products specifically designed for golf course construction?: Yes, there are earthwork products specifically designed for golf course construction. These products include specialized blends of soil, sand, and other materials that are formulated to meet the specific requirements of golf course construction, such as proper drainage, turf establishment, and playability. They are used to create the desired contours, slopes, and features of the golf course, ensuring optimal playing conditions.

Q:Can earthwork products be used for constructing embankments?: Yes, earthwork products can be used for constructing embankments. Earthwork products such as soil, clay, sand, or gravel are commonly used to build embankments, which are raised structures designed to support roads, railways, or waterways. These materials are often compacted and shaped to create a stable and strong embankment that can withstand the weight and pressure of the intended use.

Q:Can earthwork products be used for foundation stabilization?: Yes, earthwork products such as geotextiles, geogrids, and geomembranes can be used for foundation stabilization. These products are designed to improve the stability, strength, and durability of soil and foundations.
