　　Filtration and Separation

　　One of the primary functions of PET non woven geotextile is filtration and separation. When used in conjunction with sand, the geotextile acts as a barrier that allows water to pass through while preventing the migration of fine sand particles. This is crucial in applications such as road construction, where the geotextile is placed between the subgrade and the base course to prevent the mixing of different soil layers. The sand provides a stable medium for the geotextile to perform its filtration function, ensuring the long - term integrity of the structure.

　　For instance, in a road project, the Staple Fiber Needle Punched Nonwoven Geotextile can effectively separate the sand layer from the underlying soil. The geotextile's porous structure allows water to drain through, while the sand particles are retained on one side. This separation prevents the weakening of the road base due to soil intrusion, which can lead to rutting and cracking over time.

　　Reinforcement

　　Sand can also enhance the reinforcement capabilities of PET non woven geotextile. When the geotextile is embedded in sand, the sand particles interlock with the fibers of the geotextile, creating a composite material with improved strength and stability. This is particularly useful in slope stabilization projects.

　　In a slope protection application, the Needle Punched Nonwoven Geotextile is placed on the slope surface and covered with a layer of sand. The geotextile helps to distribute the load of the sand and any additional soil or vegetation on the slope, reducing the risk of soil erosion and slope failure. The sand, in turn, provides lateral support to the geotextile, preventing it from being pulled out or deformed under stress.

　　Erosion Control

　　In coastal and riverbank erosion control projects, sand and PET non woven geotextile work together to protect the shoreline. The geotextile is placed on the beach or riverbank, and sand is then placed on top of it. The geotextile helps to hold the sand in place, preventing it from being washed away by waves or currents.

　　The Non Woven Needle Punched Polyester Geotextile is often used in these applications due to its high strength and durability. The sand provides a natural buffer against the erosive forces, while the geotextile acts as a stabilizing element. This combination can significantly reduce the rate of erosion and protect valuable coastal and riverine habitats.
