Why Do Retaining Walls Fail?

Exposed to the hard elements of nature while holding back the pressure from large mounds of soil, retaining walls lose their strength over the years. below are some typical culprits behind retaining wall failure:

  • Poor Drainage – Water weakens the structural integrity of retaining walls, if they are exposed to high levels of moisture due to poor drainage then your retaining walls could deteriorate faster.
  • Improper Installation – If the retaining wall does not have a durable foundation or if it is not installed properly, it worsens much faster.
