Reinforced PVC Dam Liners for Water Storage & Containment
Geosynthetics Africa supplies high-performance reinforced PVC dam liners in thicknesses ranging from 550gsm to 1200gsm, engineered for agricultural dams, irrigation reservoirs, mining water storage, aquaculture ponds, and environmental containment across South Africa and the African continent.
Our reinforced PVC geomembranes combine flexibility, tensile strength, UV stability, and dimensional integrity — making them ideal for exposed water storage applications where long-term waterproofing reliability is critical.
For potable water storage, we offer a certified 720gsm PVC liner approved for safe drinking water applications. This food-grade PVC geomembrane complies with SANS and relevant international standards, ensuring suitability for municipal and agricultural potable water projects.
PVC Dam Liner (Reinforced)
Why Choose Reinforced PVC Dam Liners?
Reinforced PVC dam liners are engineered for reliable water retention, superior tear resistance, and long-term dimensional stability in exposed containment applications. The integrated high-strength polyester scrim reinforcement enhances tensile performance, puncture resistance, and structural integrity compared to unreinforced PVC membranes.
Unlike rigid geomembranes, reinforced PVC offers improved flexibility and surface conformity, making it particularly suitable for agricultural reservoirs, irrigation dams, aquaculture ponds, and industrial water storage across Southern Africa.
