Cracked Retaining Wall?

Types of Retaining Wall Cracks

Description: These cracks form parallel to the ground and are typically a result of lateral pressure from the soil behind the wall. They can be a serious indication that the wall is failing to hold back the earth.

Significance: Horizontal cracks often signal significant structural issues, requiring immediate attention to prevent potential wall failure.

Description: Vertical cracks may appear due to uneven settling of the foundation or changes in the ground conditions beneath the wall. They are generally less severe than horizontal cracks.

Significance: While not always a sign of structural failure, vertical cracks should be monitored as they can lead to water ingress and further damage.

Description: Step cracks appear in a zigzag pattern, typically in segmented retaining walls made of blocks or bricks. These cracks follow the joints between the masonry units.

Significance: Step cracks may indicate differential settling or shifting of wall segments and can allow water penetration, worsening the damage.

Repeated expansion and contraction of the wall materials due to temperature changes can cause fatigue, resulting in cracks over time.

Excessive lateral pressure from heavy or saturated soil can overwhelm the wall, causing it to strain and crack.

Tree or shrub roots growing near or under the wall can push against the structure or grow into small fissures, widening them as they expand.

Inadequate design or construction can weaken walls, making them susceptible to cracking under regular pressures.

Poor drainage can lead to water buildup behind the wall, increasing hydrostatic pressure that stresses the wall structure and leads to cracks.

Seismic activity, settling, or erosion can alter the ground that supports the retaining wall, leading to instability and cracking.
