Geotextiles help in preventing soil erosion on slopes by acting as a protective barrier. They are engineered fabrics that are placed on the slope surface to stabilize the soil and control water flow. Geotextiles allow water to percolate through while retaining the soil particles, thus reducing the impact of rainfall on the slope and preventing erosion. Additionally, they help in reinforcing the soil structure, providing stability to the slope and preventing the loss of soil due to gravitational forces or surface runoff.
Geotextiles act as a barrier between soil and water, allowing for better drainage and filtration. They stabilize the soil, prevent particle movement, and reduce surface erosion by increasing the overall shear strength of the slope.
