What do cracks or crumbling concrete around solar supports mean?

What you will see

• New cracks around a support or anchor location.
• Loose, flaking or crumbling concrete.
• Exposed reinforcement, rust staining or displaced material.
• A change in the support’s position or level.
• Repeated patching that does not prevent the damage returning.
• A thin surface topping and the underlying structural concrete are not necessarily the same material. Ask the inspector to identify what has actually deteriorated.

Why it happens

Concrete cracking can relate to moisture and temperature movement, loading, construction practices and curing. NRMCA notes that not every crack has the same significance. A general explanation of shrinkage cannot establish that a particular support remains structurally adequate.

The anchor connection needs its own assessment. Base-material condition and the forces acting on the connection are relevant to anchor design, so damage close to an anchor should not be dismissed without checking the actual arrangement.

A repair proposal should explain the cause being addressed and whether the support can remain in service during the work. Simply covering a crack may hide a useful sign without resolving the underlying problem.

A repair should name the cause it fixes. Covering a crack may hide it.

What you can check yourself

• Save dated photographs from a safe, accessible position.
• Note whether damage is new or appears to be progressing.
• Gather construction and previous repair records.
• Mention recent storms, roof work or changes to the array.
• Keep people away from visibly loose material or a displaced support.
• Do not approach the support to test movement. If access is unsafe, describe what can be seen and let the inspection team arrange suitable access.

What not to do

• Do not push or shake the structure, hammer loose areas or tighten anchors. Do not add extra concrete or ballast without design review. Avoid painting or patching over the area before it has been documented and assessed.

When to call us

• Arrange prompt review for crumbling material, exposed reinforcement, cracks near anchors or visible movement. A support that appears unstable requires the area to be kept clear and urgent professional assessment.
