Geosynthetic clay liners prevent leakage in landfill caps by providing a barrier against the flow of liquids. These liners are made up of layers of bentonite clay sandwiched between geotextile materials. The high swelling capacity of the bentonite clay creates a low-permeability barrier that restricts the movement of water and other fluids, effectively preventing leakage from the landfill cap.
Geosynthetic clay liners (GCLs) prevent leakage in landfill caps by utilizing a composite construction that combines a layer of bentonite clay between two geotextiles. This unique design creates a barrier system that is highly effective in containing liquids and preventing their migration. The bentonite clay in the GCLs has a high swelling capacity and low permeability, which means it can absorb water and expand to form a tight seal when exposed to moisture. This swelling action, combined with the geotextiles' reinforcement and filtration capabilities, forms a robust barrier that minimizes the risk of leakage and protects the environment from potential contamination.
Geosynthetic clay liners prevent leakage in landfill caps by acting as a barrier that restricts the movement of liquids. These liners are made up of a layer of bentonite clay sandwiched between two geotextile layers. The bentonite clay swells when it comes into contact with water, creating a dense and impermeable layer. This swelling property of the clay helps to seal any potential gaps or cracks in the landfill cap, preventing the leakage of liquids such as leachate into the surrounding environment.
