The Fluid Sealing Association recommends replacing non-fatigued joints every 5-10 years based on the application. Note, that if the expansion joint is fatigued, they will need to be replaced even more frequently than that. Below is a list of fatigue signs that indicate the expansion joint should be REPLACED IMMEDIATELY!
- Major blisters, deformations, and/or ply separations
- Cracking where the fabric is exposed and torn
- The metal reinforcement is visible through the cover
- The joint feels soft or gummy from rubber deterioration
- Leakage or weeping is occurring from any surface of the expansion joint
