Walls and steep sided embankments
Unlike embankments on soft ground, walls and steep sided embankments need support from the geotextile for their
entire design life. The essence of construction is comprising the placing of the fill incorporating horizontal layers of geotextile reinforcement. As one lift of fill is completed , the geotextile is rolled out over the surface of the fill to ensure an adequate bond length.
Soil erosion is a phenomenon of transportation of soil particles by exogenous wind or water action. The erosion phenomenon starts as soon as the first particle, detached from the rest of the soil, gets carried away due to the impact of splash and velocity of flow. The traditional method for controlling the erosion was by using a flexible protective structure such as rip-rap or heavy armour stones, concrete blocks, etc. The use of a geotextile filter can simplify construction of the erosion control measure, where it replace several layers of granular filter beneath rip-rap armour stones.
