1,Introduction

GCL is a new geosynthetics. It is graded by a natural sodium bentonite particles and corresponding additive mixed together, By special technology and equipment, the bentonite particles between two layers of geotextile fixed, made of waterproof blanket, with all the characteristics of both the geotextile material, but also has excellent water (infiltration) performance.

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:Are earthwork products resistant to seismic activity?: Earthwork products, such as retaining walls and embankments, can be designed to withstand seismic activity. By incorporating proper engineering techniques and reinforcement, these structures can be made resistant to the effects of earthquakes. However, it is crucial to consider the specific location, soil conditions, and design requirements to ensure optimal seismic resistance.

Q:How are geotextile filter fabrics used in earthwork?: Geotextile filter fabrics are used in earthwork to prevent the mixing of different soil layers, control erosion, and enhance the stability and drainage of the soil. These fabrics act as a barrier that allows water to pass through while retaining the soil particles, preventing the loss of fine particles and the clogging of drainage systems. Additionally, they can be used to separate different soil layers, preventing the migration of fine particles into coarser layers. Overall, geotextile filter fabrics play a crucial role in improving the performance and longevity of earthwork structures.

Q:Can earthwork products be used for underground drainage systems?: Yes, earthwork products can be used for underground drainage systems. These products, such as geotextiles, geogrids, and geocomposites, are commonly used in underground drainage systems to improve filtration, soil stabilization, and water flow management. They help prevent soil erosion, retain moisture, and enhance the overall performance and longevity of the drainage system.

Q:Are earthwork products suitable for road construction?: Yes, earthwork products such as soil, gravel, and rocks are commonly used in road construction. These materials are suitable for building and stabilizing road surfaces, creating embankments, and constructing drainage systems.

Q:What are the advantages of using geotextiles in shoreline habitat restoration projects?: Using geotextiles in shoreline habitat restoration projects offers several advantages. Firstly, geotextiles help stabilize the soil and prevent erosion, providing a stable foundation for shoreline vegetation to grow and flourish. This helps protect the shoreline from further degradation and enhances habitat resilience. Additionally, geotextiles act as a physical barrier, preventing invasive species from infiltrating the restoration site and allowing native plants to establish and thrive. Moreover, these textiles facilitate water filtration and drainage, improving water quality and creating a healthier ecosystem for aquatic species. Overall, geotextiles play a crucial role in enhancing the success and long-term sustainability of shoreline habitat restoration projects.

Q:What are the specific applications of geogrid-reinforced walls in earthwork projects?: Geogrid-reinforced walls have several specific applications in earthwork projects. These include slope stabilization, retaining walls, and erosion control. Geogrids are highly effective in stabilizing slopes and preventing soil erosion by providing reinforcement and increasing the overall tensile strength of the soil. They are also commonly used in the construction of retaining walls, providing additional support and preventing soil movement. Overall, geogrid-reinforced walls play a crucial role in enhancing the stability and longevity of earthwork projects.

Q:Can earthwork products be used for retaining walls?: Yes, earthwork products can be used for retaining walls. Earthwork products such as geogrids, geotextiles, and geomembranes are commonly used in retaining wall construction to provide stability, erosion control, and reinforcement. These materials help to retain the soil behind the wall and prevent it from moving or eroding, ensuring the structural integrity of the retaining wall.

Q:Can earthwork products be customized to specific project requirements?: Yes, earthwork products can be customized to specific project requirements.

Q:A project with autoclaved aerated concrete block masonry facade, the autoclaved aerated concrete block after a week after the masonry, the project completed a month later, the wall cracks, try to analyze the reasons and put forward solution.: Autoclaved aerated concrete block is characterized by a large drying shrinkage, the kettle after a week that is masonry, is not completely dry caused by shrinkage cracking.

Q:How do geosynthetic meshes help in soil separation?: Geosynthetic meshes help in soil separation by creating a barrier between different soil layers, preventing them from mixing and maintaining their individual characteristics. This separation enhances the stability and strength of the soil structure, reduces the risk of erosion, and allows for efficient drainage and filtration.
