While lots of different materials can be used in secondary containment systems, HDPE (High-Density Polyethylene), and RPE (Reinforeced Polyethylene), are some of the most common. These materials are often chosen because of their high level of chemical resistance, durability, and flexibility. Other materials can include PVC, fiberglass, concrete, and steel.
The choice of material depends on factors such as the type of stored substances, environmental conditions, and regulatory requirements. HPDE and RPE liners are particularly popular due to their versatility, cost-effectiveness, and ease of installation, making them a preferred choice for many secondary containment applications.
