Geosynthetics are synthetic fabrics that are used in a variety of civil engineering applications, including landfill construction. Geotextiles are commonly used in landfill construction because they can improve the stability and performance of the landfill, while also reducing maintenance and repair costs.
Geotextiles in landfills
One common use of geosynthetics in landfill construction is as a containment layer. An impermeable layer is placed between the waste materials and the underlying soil to prevent the waste materials from coming into contact with the soil. This helps to prevent leachate or liquid that has been contaminated by the waste materials, from infiltrating the soil and potentially contaminating groundwater. Heavy-duty geotextiles are an effective material to protect these containment layers on both sides, making sure the layer is not damaged by waste or granular material.
Another use of geosynthetics in landfill construction is as a reinforcement and erosion control layer. Geotextiles can be used to reinforce the structure and improve the overall stability of the landfill. For example, geosynthetics can be placed on the surface of the waste materials and covered with a layer of soil to provide additional support and help prevent erosion. Geosynthetics can also be used to reinforce the sides of the landfill to help prevent landslides.
Geotextiles and drainage composites can also be used in landfill construction to help with drainage. Geotextiles and drainage composites can be placed below the waste materials to allow water to drain away, helping to prevent standing water and reducing the risk of leachate formation.
Overall, geotextiles are a valuable tool in landfill construction because they can improve the stability and performance of the landfill, while also reducing maintenance and repair costs.
