Secondary containment systems are designed to accommodate expansion and contraction to prevent damage and maintain their integrity. Materials like HPDE/RPE liners are flexible and can adjust to changes in temperature and ground movement without compromising their effectiveness.
Containment walls, berms, or barriers are also engineered to withstand lateral forces and remain intact during these events. Flexible seals and expansion joints may also be incorporated into the design to allow for movement without causing damage.
