The 6 Best Reinforced Polypropylene Geomembranes Reviewed

In the rapidly advancing domain of geotechnical engineering and environmental containment, reinforced polypropylene (RPP) geomembranes emerge as a cornerstone for robust, flexible barriers that excel in demanding exposed and subsurface applications. As of 2025, the global geomembranes market—valued at USD 2.61 billion and forecasted to expand at a CAGR of 6.61% to USD 3.60 billion by 2030—highlights RPP’s niche dominance in sectors like mining (25% market share) and water management (20%), where its superior UV stability and chemical resistance prevent 95% of fluid migration per ASTM D5887 standards.
