What impact does a textured surface have on geomembranes used in landfill operations?

A textured surface on geomembranes significantly enhances frictional resistance, which is crucial in landfill operations. This increase in friction helps to prevent slippage between layers in applications such as landfill liners and caps. Increased frictional resistance improves the overall stability of the constructed landfill, especially on slopes, by reducing the likelihood of geomembranes shifting or sliding under pressure or during seismic events.

In the context of landfill operations, a higher frictional resistance also aids in the proper functioning of the landfill by ensuring that the geomembrane remains secure and effectively prevents leachate migration and gas emissions. This property is vital for the long-term containment and environmental safety of landfills, making it an essential characteristic of geomembranes used in these applications.
