What Causes Retaining Wall Failures During Natural Disasters?
Retaining walls are designed to stabilize soil and hold back slopes, but under extreme stress from natural events, they can quickly become compromised. Common causes include:
- Excessive Rainfall & Flooding: Saturated soils create hydrostatic pressure behind the wall, often leading to blowouts or bulging.
- Seismic Activity: Earthquakes can shift wall foundations and loosen soil behind the wall, causing total collapse.
- Landslides: Unstable slopes due to heavy precipitation or seismic shifts can displace entire sections of retaining walls.
- Erosion & Undermining: Fast-moving water or poor drainage can wash away foundational support, causing the wall to sink or topple.
