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: Can earthwork products be used in green building projects?
- Yes, earthwork products can be used in green building projects. These products, such as excavated soil, natural stone, and recycled aggregates, can be utilized for sustainable construction practices like earth-sheltered buildings, green roofs, and natural landscaping. By using locally sourced and recycled earthwork materials, green building projects can reduce environmental impact, promote biodiversity, and enhance energy efficiency.
- Q: How do geogrids improve the load-bearing capacity of pavements?
- Geogrids improve the load-bearing capacity of pavements by providing reinforcement and enhancing the overall stability of the structure. They distribute the applied load more evenly across the pavement surface, reducing stress concentrations and preventing the formation of cracks and deformations. Geogrids also increase the tensile strength of the pavement, allowing it to withstand heavy loads and traffic.
- Q: Why civil engineering materials are important
- Look at the current international and domestic trends to compare these three kinds of materials, while the performance of the material itself is to limit the application of its factors.
- Q: Can earthwork products be used in coastal protection projects?
- Yes, earthwork products can be used in coastal protection projects. They can be utilized to build protective structures such as berms, dunes, and seawalls, which help prevent coastal erosion and protect the land from rising sea levels and storm surges. These earthwork products, such as soil, rocks, and sand, are often used to strengthen and stabilize the coastline, providing effective coastal protection measures.
- Q: Are earthwork products resistant to UV radiation?
- Yes, earthwork products are generally resistant to UV radiation.
- Q: What is the role of geosynthetic reinforcement in retaining wall construction?
- The role of geosynthetic reinforcement in retaining wall construction is to provide additional strength and stability to the wall. It helps to distribute the forces and pressures exerted by the retained soil, reducing the risk of wall failure and improving overall performance. Geosynthetic materials such as geogrids or geotextiles are commonly used to reinforce retaining walls, enhancing their ability to resist lateral forces and improve long-term durability.
- Q: Can geopipes be used for drainage systems?
- Yes, geopipes can be used for drainage systems. Geopipes are designed to effectively collect and transport water, making them suitable for various drainage applications such as stormwater management, subsurface drainage, and agricultural drainage systems.
- Q: How do earthwork products contribute to slope stabilization and erosion control on highways?
- Earthwork products such as geotextiles, geogrids, and erosion control blankets are essential in slope stabilization and erosion control on highways. Geotextiles, for instance, act as filters, allowing water to pass through while preventing the loss of fine soil particles. This helps to reduce erosion and maintain the stability of the slope. Geogrids, on the other hand, provide reinforcement and structural support to the soil, preventing it from sliding down the slope. Erosion control blankets function as protective covers, shielding the soil from the impact of rain and wind, thereby reducing erosion. These earthwork products work together to enhance the durability and safety of highways by mitigating slope instability and erosion risks.
- Q: How do geotextile tubes compare to traditional construction methods?
- Geotextile tubes are a more cost-effective and environmentally friendly alternative to traditional construction methods. They offer faster installation, reduced labor requirements, and minimized disturbance to surrounding areas. Additionally, geotextile tubes are highly durable and provide excellent erosion control and sediment containment.
- Q: How do geogrids aid in reinforcement of tunnel walls in earthwork applications?
- Geogrids aid in the reinforcement of tunnel walls in earthwork applications by providing additional strength and stability to the surrounding soil. These synthetic materials are installed within the earthwork layers to distribute the loads and tension forces more evenly, preventing soil movement and potential collapse. This reinforcement technique enhances the overall structural integrity of the tunnel walls, ensuring a safer and more durable construction.
