Benefits of using Impact resistant, flexible flood markers and guideposts
Continuous visibility and guidance
- Self-recovering designs stay upright and legible after strikes, maintaining lane edge, and depth guidance.
- Better resilience in seasonal events (flooding, storms).
Reduced maintenance and product lifecycle cost
- Fewer post replacements and less call-out time after impacts.
- Lower spend on traffic control, crews, and parts over the asset’s life.
Improved safety outcomes
- Energy-absorbing, passively safe posts reduce vehicle damage and injury risk compared to rigid alternatives.
- Maintained delineation in flood-prone or low-visibility zones reduces the risk of collisions, or road users leaving the road or causeway.
