Bridge Repair

How Natural Disasters Cause Bridge Failures

When disaster strikes, the impact on bridges and adjacent infrastructure can be catastrophic. Common natural hazard threats include:

• Flooding and Scour: Undermining bridge piers, abutments, or embankments
• Earthquakes: Causing foundation damage, deck displacement, or structural instability
• Landslides and Debris Flows: Blocking or damaging bridge approaches and access roads
• Wildfires: Weakening slope integrity and making structures vulnerable to post-fire erosion
• Heavy Rain and Storm Events: Leading to embankment collapse, sinkholes, and structural movement

These conditions often lead to dangerous instability not only at the structure, but throughout the surrounding terrain. Our approach focuses on repairing both the bridge system and the underlying geohazard.
