How to choose woven or non woven geotextile?
When choosing between woven and non-woven geotextiles, it’s essential to consider the specific requirements and conditions of your project. Here are some factors to keep in mind when deciding:
1.Function: Determine the primary function of the geotextile in your application. Woven geotextiles are typically used for separation and stabilization purposes, where the fabric’s strength and load-bearing capacity are crucial. Non-woven geotextiles, on the other hand, are often used for filtration and drainage, as they have excellent water flow properties.
2.Strength and Load-Bearing Capacity: Woven geotextiles are generally stronger and more durable than non-woven geotextiles. If your project involves heavy loads, such as roadways or retaining walls, woven geotextiles may be more suitable due to their higher tensile strength.
3.Filtration and Drainage: If your project requires effective filtration and drainage, non-woven geotextiles are typically the preferred choice. They have a high permeability, allowing water to pass through while preventing soil particles from clogging the fabric. This property is especially important in applications such as drainage systems, erosion control, and filtration of fine particles.
4.Soil Conditions: Consider the soil conditions at your site. Non-woven geotextiles are often more effective in areas with cohesive soils or fine particles, as they can prevent soil migration and maintain stability. Woven geotextiles, on the other hand, may be better suited for sites with coarser soils.
5.Cost: Cost can also be a determining factor. Non-woven geotextiles are generally less expensive than woven geotextiles. If your project requirements can be met by a non-woven geotextile, it may provide a more cost-effective solution.
Remember to consult with geotechnical engineers or experienced professionals who can assess your specific project needs and provide recommendations based on their expertise. They can help you make an informed decision by evaluating factors such as soil characteristics, expected loads, hydraulic conditions, and design specifications.
