Geomembranes, including materials like HDPE, RPE, and CSPE, are commonly used for wastewater containment liners thanks to their impermeability, durability, and chemical resistance, making them suitable for long-term containment with minimal risk of contamination.
The best material for any given situation depends largely on the nature of the wastewater and the containment structure itself. CSPE geomembranes work well when the chemical challenges are extreme, while HDPE is flexible and UV-resistant. RPE is reinforced for long term durability, offering the strengths of HDPE in a lightweight, easy-to-handle material.
