How to Inspect the Basement Floor Structure

While the inspector is in the basement they should check the floor structure for any visible damage, including cracks. If the floor is covered the inspector should use the “Not Inspected” comment in the software. Please review the entire procedure.

Axium SOP Differences

Axium Requires: The inspector will check the basement floor structure.

 

Tools Needed

No tools required to inspect the basement floor structure.

 

Procedure

  • While inspecting the basement we will want to check the basement floor structure and specifically check for any cracking on the floor. There are no pictures required for this section unless there is a defect.

Common Defects

  • There are cracks present on the concrete slab floor.
  • There is heaving and/or settling that may have occurred to the basement floor under the floor covering.

 

Common Mistakes

  • Not checking the entire floor for any cracking and/or heaving.
  • Not using the “Not Inspected” comment if the floor is covered and you aren’t able to determine the basement floor structure.

 

Report / Software

IN


  • Concrete Slab on Grade: The basement had a concrete slab on grade floor construction. Some minor cracks in the concrete are typical and to be expected. (Examples will be noted in attached photos).
  • Floating Wood: The basement had a floating engineered wood floor.
  • Floating Concrete: The basement had a floating engineered concrete floor.

NI

  • Most or all of the basement floor was covered at the time of the inspection, and could not be fully evaluated.

NP

  • N/A

RR

  • Repair/Replace: The basement had a concrete slab on grade floor construction. Cracks in the basement floor were observed as was some heaving and/or settling. Recommend sealing these cracks to prevent moisture intrusion, and monitoring for further movement. For further analysis, consulting with a licensed structural engineer is recommended.
  • Under Floor Covering: The basement had a concrete slab on grade floor construction. Cracking, heaving and/or settling may have occurred to the basement floor under the floor covering. Recommend sealing these cracks to prevent moisture intrusion, and monitoring for further movement. For further, analysis, consulting with a licensed structural engineer is recommended.
  • Large Cracks: The basement floor was a concrete slab on grade. At least one fairly significant crack was observed, with a gap of at least 1⁄4 inch. Recommend sealing the cracks to prevent moisture intrusion. Further analysis by licensed structural engineer is recommended.
