How to choose Geotextile?
1. Material and quality:
High quality geotextiles are usually made from high strength synthetic fibers such as polyester or polypropylene fibers. These materials have good corrosion resistance, aging resistance, and tensile strength.
Check the uniformity and fineness of the fiber, and the geotextile with uniform fiber distribution and appropriate fineness is more stable. For example, in some water conservancy projects, the use of high-quality polyester fiber geotextile cloth can effectively prolong the service life of the project.
2. Strength and elongation ratio:
Geotextile cloth with appropriate strength should be selected according to the specific engineering requirements. High-strength geotextiles can withstand greater loads and stresses.
At the same time, the elongation rate cannot be ignored. Geotextile with a certain elongation rate can adapt to the deformation in the project without breaking easily. For example, in the road engineering, the need to bear the repeated rolling of vehicles, the need for good strength and elongation of the geotextile.
3. Permeability and filtration performance:
If used for drainage or filtration, pay attention to the permeability and filtration performance of geotextiles. Geotextile with good permeability can drain water quickly, while good filtration performance can prevent the loss of soil particles.
In the overlay of landfills, geotextiles with excellent permeability and filtration performance are needed to prevent leachate from polluting groundwater.
4. Thickness and weight:
Different works have different requirements on the thickness and weight of the geotextile. Generally speaking, thicker and heavier geotextiles have better durability and protective performance, but are also relatively costly.
For example, in large embankment reinforcement projects, thicker geotextiles may be selected to enhance the protective effect.
5. Chemical corrosion resistance:
Considering the environment of the project, if chemical substances exist, the geotextile with good chemical corrosion resistance should be selected.
For example, in soil remediation projects near chemical plants, geotextiles need to resist chemical erosion.
6. Brand and supplier reputation:
