Retaining wall structures can fail due to a variety of factors, including inadequate design, poor construction practices, or external environmental forces. Insufficient design considerations, such as improper load calculations or ineffective drainage provisions, can lead to structural instability over time. Construction flaws, including inadequate compaction of backfill materials or the use of substandard materials, can compromise the wall's integrity. Additionally, natural elements like heavy r
