Where are extrusion welds particularly useful in geomembrane installations?

Extrusion welds are particularly useful in geomembrane installations in small areas with irregular shapes because of their ability to provide strong, localized bonding between geomembrane sheets. These welds are applied using specialized equipment that melts and extrudes a plastic material along the seam, ensuring a robust join that can accommodate the complex curves and angles typically found in smaller, irregularly shaped areas. This technique allows for flexibility in the installation process, minimizing the risk of gaps or weaknesses where different sections of geomembrane meet.

In contrast, other scenarios, such as large, flat areas, underwater conditions, or areas exposed to high temperatures, may not leverage the benefits of extrusion welding to the same extent. Large, flat areas can often make use of simpler joining techniques that do not require the same level of complexity as extrusion welds. Underwater installations present unique challenges related to water pressure and may require specialized techniques that differ from standard extrusion welding. High-temperature environments could affect the welding material's performance and longevity, thus making alternative welding or joining methods more suitable.
