Thread: Settlement under footing

SF home built in 1980. Settlement or grade was present along the footing is vasious areas. The walls were free of cracking. It there any amount of acceptable settlement or do you call for further evaluation.

I'm not too crazy about that pier repair, or the gaps at the footings. I would be telling my clients they needed someone (engineer) to look at it.

The repair was in there by mistake. I was concerned above the settlement, just wanted a feel for how you address the settlement.

No answer, just a question.
Is it common to see the footing on top of the soil?

A footing on soil. Never right. Obviously it was not undisturbed soil. If they are were using that as a structural wall it should have been installed as any proper footing and not just poured on top of disturbed soil.

Engineer? I don't know about that but at least a good foundation company. No noticeable movement to the home? Well, the "footing" as they call it, moved or the soil under it. What is the next step.

Absolutely, write it up for a foundation company. Foundation companies will got eh next step to an engineer if needed. Or an in house engineer to draw it up.

Oh yeah, and the other fixes needed.

No, none is acceptable.

The footing is supposed to be supported on the soil it was placed on. If that was a grade beam (it is not), then no soil support is required, it is designed to serve as a "beam" placed at or below grade.

... or do you call for further evaluation.

No ... ... I would call for a structural engineer to design appropriate repairs.

Ted referenced a foundation company, most foundation companies I've know had their own engineer on staff (usually the owner of the foundation company), that or they contracted with an structural engineer they worked closely with on a regular basis.

I prefer the engineer route, let them design the appropriate repair, they will have a foundation company they work for or work with.

Either way - *you* did the 'evaluation', now it just needs to be 'repaired'.

that cinder block support is way wrong --hollow in always down

While agreeing with all other posts; this is a good example of what well placed rebar can do. (1980 and no cracks!)

Additionally, I would also further evaluate the drainage issues with this building, as it appears to indicate the possibility of washout as well as subsidence.

I don't understand the part about the footing. Isn't the footing under the concrete slabs that make up the foundation? The ring around the interior is something (among many!) I haven't seen - is that part of construction for seismic zones, or what? Where the floor would go?

Is this under a porch?

Well? Am I way off base(ment)?

What's the strapping on the walls here - is it for the attachment of a stud wall? Or part of the production process of making the slabs? I suppose that's it - the straps hold the boards up. I don't encounter this kind of thing.
