Does geotextile fabric let water through

Geotextile fabric, specifically designed for civil engineering and landscaping applications, does allow water to pass through. There are two main types of geotextile fabrics: woven and nonwoven.

Woven Geotextiles: These are made by weaving fibers together. They have a higher tensile strength and are used in applications where strength is crucial, such as road construction. They allow water to pass through but at a slower rate compared to nonwoven geotextiles.

Nonwoven Geotextiles: These are made by bonding fibers together using heat, chemicals, or other methods. They have a higher permeability, allowing water to flow through more easily. They are often used for filtration and drainage applications.

Both types are used to separate, filter, reinforce, protect, or drain soil, allowing water to pass through while preventing soil erosion and promoting stability. The choice between woven and nonwoven geotextile depends on the specific requirements of the project.
