Cracks in retaining walls can signal significant structural concerns, potentially leading to further damage if not addressed promptly. At APD Foundation Repair, we expertly assess and repair these crucial signs to prevent expensive repairs and ensure the stability and longevity of your property. Read below to discover the types of retaining wall cracks and their common causes.
Types of Retaining Wall Cracks
Understanding the different types of retaining wall cracks can help homeowners identify potential issues early and determine the right course of action for repair.
Horizontal 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.
Vertical Cracks
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.
Step Cracks
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.
Common Causes of
Retaining Wall Cracks
Understanding the different causes of retaining wall cracks can help homeowners identify potential issues early and determine the right course of action for repair.
Temperature Fluctations
Repeated expansion and contraction of the wall materials due to temperature changes can cause fatigue, resulting in cracks over time.
Soil Pressure
Excessive lateral pressure from heavy or saturated soil can overwhelm the wall, causing it to strain and crack.
Root Intrusion
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.
Poor Construction
Inadequate design or construction can weaken walls, making them susceptible to cracking under regular pressures.
Water Accumulation
Poor drainage can lead to water buildup behind the wall, increasing hydrostatic pressure that stresses the wall structure and leads to cracks.
Ground Movement
Seismic activity, settling, or erosion can alter the ground that supports the retaining wall, leading to instability and cracking.
