Notice changes in a retaining wall
Visible changes can help a professional understand a wall’s condition. Observe from a safe location and avoid disturbing a wall that may be unstable.
What you'll learn
- Which visible changes call for a professional assessment
- Why a symptom does not establish its cause
- What to do when a wall or slope may be unstable
Step by step
- Look from a safe place If a wall or slope appears unstable, keep people away and seek a qualified assessment. Do not approach it for a closer measurement.
- Note what changed From a safe position, record any visible lean, bulge, widening crack, staining, or movement in the surrounding ground.
- Consider the surrounding ground Changes in nearby ground or new water at the surface can be relevant to slope movement. FEMA lists moving retaining walls and widening ground cracks among possible landslide warning signs; these signs alone do not diagnose the cause.
- Ask for an assessment Share the observations and any available plans with a qualified professional. A photograph alone cannot establish the cause or safety of a wall.
If movement appears active or people may be in danger, stay clear and contact the appropriate local emergency service.

Recognize retaining wall drainage concerns
A drainage outlet is one part of a wall system. Note visible water or staining from a safe location and ask a professional to assess the wall and its drainage.
Gather wall dimensions for a permit discussion
Permit measurements and other triggers depend on the authority serving the property. Share available plans and visible dimensions with the building department or a qualified professional.
Describe your retaining wall material
A description and photographs can help a contractor prepare for a discussion. A professional can assess visible conditions; concealed details may need further investigation.
