- Q: Can geotextiles be used in the construction of reservoirs?
- Yes, geotextiles can be used in the construction of reservoirs. Geotextiles are commonly used as a separation and filtration layer in reservoir construction to prevent the mixing of different soil layers, provide stability, and control erosion. They can be deployed to reinforce embankments, line channels, or act as a barrier against seepage, ultimately enhancing the overall performance and longevity of the reservoir.
- Q: What is the separation between the roof waterproof protective layer and the waterproof layer?
- The meaning of the protective layer and the isolation layer is not the same, figured out the role and meaning of nature know how to set up. 1, the protective layer of the waterproof layer contains a two-tier meaning. First, if there are other waterproof layer above the construction layer, due to the construction process may cause damage to damage to water, so need to do protective layer; Second, the roof is the function of the master or planting, the activities of personnel may cause damage to water , Need to do protective layer. 2, the role of the isolation layer is also divided into two kinds. First, to prevent the adverse effects of the two kinds of materials (incompatible), with the isolation layer for the interface, such as PVC coil and polystyrene foam insulation board, because the plasticizer in the membrane will migrate , The direct contact with the benzene plate will produce melt damage; Second, the coil surface of the rigid layer, may be due to thermal expansion and contraction deformation affect the waterproof layer, in the rigid layer of the larger part of the deformation, Too large and damage the waterproof layer, then need to set the isolation layer. There is a geotextile isolation layer between the waterproofing membrane and the pebble press material. 3, not all of the waterproof layer and the protective layer between the need for isolation layer. When the cement mortar is used as the protective layer, the cement mortar may be directly applied to the waterproof surface. When the flexible protective material (heat reflective coating, etc.) or the insulation layer is used, the isolation layer is not required.
- Q: What are the considerations for geotextile selection in railroad projects?
- When selecting geotextiles for railroad projects, several considerations need to be taken into account. Firstly, the geotextile should have sufficient strength to withstand the loads and stresses imposed by train traffic. It should also possess excellent puncture resistance to ensure long-term durability. Additionally, the geotextile should have good filtration properties to prevent fine particles from entering the subgrade and causing drainage issues. It is important to consider the geotextile's permeability, as it should allow for adequate drainage to maintain the stability of the railway track. Lastly, the geotextile's compatibility with other materials used in the project, such as ballast or subgrade soils, should be evaluated to ensure proper functioning of the system.
- Q: Are geotextiles suitable for use in railway ballast stabilization?
- Yes, geotextiles are suitable for use in railway ballast stabilization. Geotextiles can improve the stability and performance of railway ballast by preventing the mixing of ballast and subgrade soils, reducing track settlement, improving drainage, and enhancing overall load-bearing capacity. They also help in reducing maintenance needs and increasing the lifespan of the railway tracks.

- Q: How do geotextiles help in gas venting?
- Geotextiles help in gas venting by providing a permeable barrier that allows the passage of gases while preventing the migration of soil particles. This allows gases, such as methane, to escape from the ground, reducing the risk of buildup and potential hazards.
- Q: How do geotextiles help in reducing the risk of soil liquefaction?
- Geotextiles help in reducing the risk of soil liquefaction by providing reinforcement and stabilizing the soil. They act as a barrier to prevent the movement of water within the soil, reducing the buildup of excess pore water pressure. This pressure is a major factor contributing to soil liquefaction during earthquakes. By promoting drainage and improving soil strength, geotextiles help to mitigate the potential for liquefaction and increase the overall stability of the soil.
- Q: Can geotextiles be used in green roof drainage systems?
- Yes, geotextiles can be used in green roof drainage systems. Geotextiles are commonly used as a filtration layer in green roof systems to prevent clogging of the drainage layer. They help in retaining water and reducing runoff, thereby improving the overall drainage efficiency of the green roof.
- Q: What are the different types of geotextiles?
- There are several types of geotextiles, including woven geotextiles, non-woven geotextiles, and knitted geotextiles. Each type has its own unique properties and characteristics that make them suitable for various applications in civil engineering, construction, and environmental projects.
