Concrete Inspections

Why Inspect Concrete?

Five or ten years after this slab is poured, do you think anyone will remember where the rebar, conduit, and PT cables are?

Concrete/Construction Services

Concrete coring and sawcutting can be risky, especially if you don’t know what’s in the concrete before you start work. In many cases, the risks can be eliminated by using x-ray techniques prior to coring or sawcutting in order to locate rebar, post-tensioned cable, and conduit.

International Inspection, Inc. will perform concrete x-ray inspections anytime (24 hours) and develop the resulting film on site for immediate results. Concrete contents are then indicated on the surface using permanent markers, unless indicated otherwise.

  • Licensed by the State Radiological Health Department
  • State-approved Radiation Safety Officer on Staff
  • State licensed technicians trained and certified in Radiation Health & Safety

Highly-occupied Sites – Highly occupied sites such as hotels, hospitals, casinos, etc. where evacuating two floors to perform x-ray inspections is impractical may require an alternate inspection method. An excellent alternative is our Subsurface Interface Radar (SIR) inspections.

One-side accessibility – SIR would also be the method of choice for slabs on grade, retaining walls, and other conditions where only one-side accessibility is available.


In order to assure a safe environment for site staff & our personnel as required by state law, general guidelines must be met. Please see our List of Concrete X-Ray Guidelines. To request a sample Notice To Tenants, please contact one of our offices and we will be happy to e-mail or fax a copy to you.

Image Technique Selection

Depending on your exact project requirements International Inspection can help you specify the use of x-ray or subsurface interface radar. On many projects a combination of the two methods can improve job site safety and reduce costs.
