What is the water permeability of geotextile? The water permeability of the geotextile refers to the ability of water to pass through the geotextile. Water permeability is an important performance indicator for evaluating geotextiles and is crucial for many geotechnical applications. Generally speaking, the water permeability of geotextile is closely related to its material and […]

How to judge the quality of woven geotextile? To judge the quality of woven geotextiles, you usually need to consider the following aspects: Material selection: Appropriate materials should be selected for high-quality woven geotextiles. Commonly used materials include polypropylene (PP), polyester (PET), etc. These materials should have excellent strength, durability and chemical resistance. Weight and

Do lakes need geotextiles? In lake projects, geotextiles are usually not a necessity. Compared with geomembranes, the application of geotextiles in lake projects is relatively limited. However, there are situations where geotextiles may be used for specific purposes, depending on the specific engineering design and environmental conditions. 1. Lakeshore protection: When protection or protection projects

Is the anti-seepage effect of filament geotextile better? Filament geotextiles generally have better anti-seepage effects than short-filament geotextiles, but the specific effects also need to consider the specific application scenarios and needs. Filament geotextiles are composed of continuous filaments and have high tensile strength and tear resistance. Their fibers are longer and continuous, helping to

How does geotextile prevent seepage? Geotextiles are materials made from polymer fibers or other synthetic fibers through weaving or other processes. While geotextile itself cannot prevent moisture penetration, it can provide anti-penetration capabilities in the following ways: Dispersed osmotic pressure: The fiber structure of geotextile can help disperse and spread the osmotic pressure of water.

What projects require geotextile laying? Anti-seepage projects: Geotextiles play a key role in various anti-seepage projects. This includes percolation layers in landfills, anti-seepage layers in landfills, anti-seepage layers in chemical storage tank areas, etc. By laying geotextiles, you can effectively prevent the loss of seepage water underneath or avoid the pollution of soil and groundwater.

What is singeing geotextile? Singed geotextile, the full name of polyester filament singed geotextile, includes a base layer of non-woven geotextile. There is a sintered layer on the base layer of non-woven geotextile. This product not only achieves the purpose of agglomeration on the surface of non-woven geotextile, but also It also maintains the original

What is the anti-seepage function of geotextile? The anti-seepage effect of geotextiles mainly refers to preventing the penetration of water or harmful liquids. Geotextiles are mainly composed of non-woven fabrics and geomembranes. The large number of three-dimensional pore structures in needle-punched geotextiles improve the cloth’s ability to conduct fluid on a flat surface, which is

Why do tunnels use geotextiles? Geotextiles can be used for foundation reinforcement. In tunnel construction, the stability of the foundation is of paramount importance. Geotextiles can prevent subsidence and deformation of the foundation by enhancing the strength and stability of the soil, thereby ensuring the safety and reliability of the tunnel project. Geotextiles can be

Sewing requirements for geotextile bags All stitching must be continuous, eg spot stitching is not permitted. Geotextiles must overlap a minimum of 150mm before overlapping. The minimum stitch distance from the selvage (the exposed edge of the material) is at least 25mm. The seamed geotextile seams include one row of seams and chain seams. The
