    I appreciate you explaining what spalling is and how it is caused by corroded rebars or impacts to the structure. My son is building a new garage on his property and is trying to figure out how to get it to last for as long as possible. We will keep your article in mind as he makes a plan to accomplish this task.

      You can use coated rebar in the slab which will present salt from your vehicles from corroding the rebar and causing spalling. This would only be needed if your municipality or county uses salt during the winter.

    Hi. I had 2 professional and well know foundation companies come out to do a comprehensive evaluation of my foundation. I had some spallling, “truss crush”, and a chuck of concrete came off that exposed what I thought was a rusting rebar. They had slightly different assessments of my home with one company using the aerial map of wrong house in their evaluation. They told me they used old and new Google maps to investigate if the landscape changed such as having trees around the home or things that we may not be aware of at this time of the inspection. The treatment plan included the use of multiple piles to stabilize the foundation and they were supposed to try to lift my foundation and add some kind of polyurethane to fill the space and gap. But they didn’t do this. It’s complicated as to why, but now they aren’t answering and I think my rebar has rusted more. I am seeing more cracks, wider cracks, spalling, and cracks in the drywall seams, etc. Based on your article I see problems. Who do you recommend I call to inspect my home and tell me what’s going on? A structural engineer or a civil engineer, I don’t trust either company and they are the most popular. Thank you!
