Silo Inspection Programs (Levels 1, 2, 3)

Silo Inspection

Marietta Silos Inspection Services recommends regular inspection of concrete structures to ensure their continued safety.

Marietta Silos recommends that all concrete storage silos be inspected every two to five years depending on their condition and the amount of usage.  If the silos are subject to extreme usage, an annual inspection may be appropriate.

Following the silo inspection, a report will be issued documenting the inspector's findings and listing any repair recommendations.  If repairs are necessary, Marietta Group can provide a proposal to complete these repairs through Marietta Silos or Marietta Inspection Services as appropriate.

Silo Inspection

Basic - Level 1 Inspection

Under Level 1, inspector will complete a thorough, basic inspection. We will:

  • Observe the walls, foundation and roof from the ground or other locations as available 
  • If possible, observe the silo discharge area

 

Silo Inspection

Augmented - Level 2 Inspection

Level 2 inspection is a more thorough examination that includes all items listed in the Level 1 inspection as well as:

  • Sounding of the concrete for delamination
  • Non-destructive thickness testing of the exposed silo cone area
  • If possible, inspection of the silo interior through roof and wall openings
  • And if necessary, a silo design engineer can review the inspection findings

 

Comprehensive - Level 3 Inspection

Inspection Level 3 will include Level 1 and Level 2 procedures along with:

  • An interior inspection accomplished through vessel entry, as needed 
  • Exterior rigging to allow the inspector to observe the walls
  • This level of inspection includes the services of a senior silo design engineer to observe the silo and make recommendations

Regardless of the silo inspection level chosen, every effort will be made to determine the condition of the silo or concrete structure, identify problem areas, list any recommendations and, if needed, provide a proposal to restore the structure to full serviceability.
