What Is the Most Common Cause of Retaining Wall Failure?
There is no single cause behind every retaining-wall failure, but unmanaged water is one of the most serious and common contributors. Saturated soil becomes heavier, and trapped water can create hydrostatic pressure behind the wall. Water can also erode soil at the base or carry fine soil out through gaps.

Other failures can begin with the site or construction
A weak or poorly prepared base, unsuitable backfill, inadequate reinforcement, excessive wall height, steep slopes and loads from vehicles or structures can also contribute. Several problems may act together rather than one isolated defect causing the movement.
The American Concrete Institute notes that inadequate drainage around retaining walls can increase hydrostatic pressure and contribute to cracking, leakage or structural failure.
Warning signs deserve an on-site assessment
Watch for new leaning, broad bulging, widening cracks, displaced blocks, sunken soil, persistent water flow or erosion at the toe of the wall. Do not attempt to push a moving wall back into place without first identifying the pressure behind it.
