What is the role of geotextiles in drainage systems?

The role of geotextiles in drainage systems is primarily to filter soil and water while preventing clogging. Geotextiles are permeable fabrics that facilitate the drainage of water while simultaneously allowing water to pass through the soil. They achieve this by acting as a filter that separates soil particles from the drainage medium, such as gravel or coarser materials, preventing fine particles from clogging the system. This filtering action is crucial for maintaining the efficiency of drainage systems, as it helps to ensure that water can flow freely through the system without being obstructed by soil buildup.

This function contributes to the longevity and effectiveness of drainage installations, making geotextiles an essential component in various applications, such as retaining walls, road construction, and foundation drainage systems. Their ability to manage water flow and soil stability ultimately leads to improved performance and reduced maintenance requirements for drainage systems.
