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.

- Q:How are geotextile bags used in erosion control on riverbanks?
- Geotextile bags are commonly used in erosion control on riverbanks by acting as a protective barrier against soil erosion. These bags are typically filled with sand or soil and placed strategically along the riverbank to stabilize the soil and prevent it from being washed away by the force of the water. The geotextile fabric used in these bags allows water to pass through while retaining the soil, effectively reducing erosion and maintaining the stability of the riverbank.
- Q:What is the function of geosynthetic drainage materials in road shoulder construction?
- Geosynthetic drainage materials in road shoulder construction serve the function of enhancing drainage efficiency by providing a pathway for water to flow away from the road surface. They help prevent the accumulation of water in the road shoulder, which can lead to softening of the soil and potential damage to the road structure.
- Q:Are earthwork products suitable for road verge stabilization?
- Yes, earthwork products are suitable for road verge stabilization. They provide effective erosion control, slope stabilization, and vegetation support, helping to prevent soil erosion and maintain the integrity of road verges.
- Q:What are the cost implications of using geosynthetics in earthwork projects?
- The cost implications of using geosynthetics in earthwork projects can vary depending on the specific project requirements, but generally, geosynthetics can help reduce construction costs in several ways. Firstly, geosynthetics such as geotextiles and geogrids can serve as effective soil reinforcement materials, reducing the need for traditional reinforcement methods like steel or concrete, which can be more expensive. Additionally, geosynthetics can enhance the stability and performance of soil structures, allowing for the use of less expensive fill materials. They can also improve drainage and filtration, reducing the need for costly drainage systems. Overall, while there may be an initial cost associated with incorporating geosynthetics, their long-term benefits and potential cost savings make them a cost-effective choice for earthwork projects.
- Q:How do concrete barriers enhance safety on construction sites?
- Concrete barriers enhance safety on construction sites in several ways. Firstly, they provide a physical barrier that prevents vehicles and pedestrians from entering restricted areas, thereby reducing the risk of accidents and injuries. Additionally, these barriers can mitigate the impact of any potential collisions, protecting workers and equipment from damage. Their sturdy construction and weight also make them resistant to strong winds, which helps maintain stability and prevents accidents caused by falling debris. Overall, concrete barriers play a crucial role in ensuring a safer working environment on construction sites.
- Q:Can earthwork products be used in ecological restoration projects?
- Yes, earthwork products can be used in ecological restoration projects. Earthwork products such as soil, compost, and mulch can be used to enhance soil quality, increase water retention, and promote vegetation growth, which are important aspects of ecological restoration. These products can help stabilize slopes, prevent erosion, and create a favorable environment for native plants and wildlife. Additionally, earthwork techniques like grading and contouring can be employed to reshape landscapes and recreate natural features, further contributing to the success of ecological restoration projects.
- Q:What are the aesthetic options available for earthwork products?
- The aesthetic options available for earthwork products vary depending on the desired outcome. Some common options include using different types of materials such as rocks, gravel, or mulch to create various textures and colors. Additionally, landscaping techniques like terracing, contouring, or creating mounds can enhance the overall visual appeal of earthwork products. The use of plants, flowers, and other greenery can also add to the aesthetic value by introducing natural elements into the design. Ultimately, the aesthetic options for earthwork products are limited only by one's creativity and desired aesthetic outcome.
- Q:What are the different load-bearing capacities of earthwork products?
- The load-bearing capacities of earthwork products can vary depending on the specific type of product and its intended use. Generally, materials like gravel and crushed stone have high load-bearing capacities and are commonly used as base layers for road construction. Soil and clay have lower load-bearing capacities and may be used for filling or landscaping purposes. It is important to consider the specific requirements of a project and consult with engineers or professionals to determine the appropriate earthwork products with suitable load-bearing capacities.
- Q:How do earthwork products contribute to landfill liner construction?
- Earthwork products such as clay, geomembranes, and geotextiles play a crucial role in landfill liner construction. Clay is often used as a natural barrier due to its low permeability, preventing contaminants from seeping into the ground. Geomembranes, made from synthetic materials, provide an additional impermeable layer to further prevent leakage. Geotextiles, on the other hand, act as a separation and filtration layer, preventing the mixing of different materials and allowing for proper drainage. Together, these earthwork products ensure the integrity and effectiveness of landfill liners, minimizing the risk of environmental contamination and safeguarding the surrounding ecosystem.
- Q:What are the benefits of using sediment basins?
- Sediment basins offer several benefits, including the prevention of soil erosion and sediment runoff, which can contribute to water pollution. They effectively trap sediment and prevent it from reaching nearby water bodies, preserving water quality and aquatic ecosystems. Sediment basins also help in controlling and managing stormwater runoff, reducing the risk of flooding and soil degradation. Additionally, they provide an opportunity for sediment to settle, allowing for the collection and removal of contaminants before they reach sensitive areas, thus protecting downstream habitats and infrastructure.
