Structural Failure of Retaining Wall Due to Improper Construction Practices

Why This Retaining Wall Is Failing — And Why You Need a Licensed Expert

Retaining walls are not just a decorative part of your landscaping — they serve a critical role in holding back soil, preventing erosion, and protecting structures and sidewalks from shifting. But when construction standards are violated or unqualified labor is used, these walls become a major safety risk.

⚠️ Current Condition Overview

• Deep vertical and diagonal cracks along the entire wall.
• Block separation and displacement.
• Deterioration of mortar joints and visible inner core.
• Complete lack of rebar (reinforcement), confirmed by the severity of cracking and movement.

❌ Root Cause of the Damage

The main reason for this failure is the lack of steel reinforcement (rebar). Retaining walls without proper vertical and horizontal reinforcement are highly prone to cracking and collapse, especially when exposed to:

• Clay or shifting soils,
• Pressure from elevated walkways or backfill,
• Seasonal soil expansion due to moisture.

In addition, improper block installation and the likely absence of a drainage system increase hydrostatic pressure on the wall, accelerating the damage.

👷 Why You Must Work with Professionals

This is not a cosmetic issue — it's a serious safety hazard:

• The wall could collapse and injure someone.
• Soil erosion may damage nearby landscaping, sidewalks, or neighboring property.
• Utility lines, plants, or hardscape features may be affected.
