Why Retaining Walls Need Geotextile Filter Fabric for Stability and Drainage
Retaining walls are essential structures in landscaping and construction, providing stability and preventing soil erosion in sloped areas. However, to maintain their effectiveness and longevity, retaining walls require specific materials that enhance drainage and prevent soil movement. One such critical material is geotextile filter fabric. This article explores the role of geotextile filter fabric in retaining walls, its benefits, and how it compares to other geotextile applications. Do Retaining Walls Need Filter Fabric? Yes, retaining walls typically need filter fabric to ensure proper drainage and prevent soil from clogging the drainage system. Filter fabric, often made from geotextiles, acts as a barrier that allows water to pass through while keeping soil and other particles in place. Drainage stone should always be covered with filter fabric at the top of the wall to further enhance this protection. Without this fabric, water pressure could build up behind the wall, leadin...
