Thread: Grade around footing

Do you identify this as an issue when the grade around the footing has been removed. These are footings within the crawl space of the home built in 01. 2 story, single family. Its more rock than grade

Its a problem and the soils are prone to collapse under those exposed footings.

But if the owner would like to relocate the upstairs to downstairs, its an acceptable practice.

I agree with Ray, it is a problem. The load that is being directed to those footings is not going straight down. It is directed into the earth in kind of a cone shape. that is why the supporting soils are so important.

Also agree with above and where are the FBs and wood forms left in place after a pour is a bad practice and generally non-code complying. Looks like a home owner trying to qualify as a "Darwin Candidate."

jerry,
the fb's are left intentionally to distract the termites from the bigger target

Let me continue to hammer the same nail.

I have a structural engineer buddy that says the earth needs to slope off at a 45° angle from the bottom of the footing.

I like the 45-degree angle idea myself. Been practicing it for more than 40 years.

The first picture does show how small applied loads actually can be in many scenarios. Any significant vertical loads on the concrete would have collapsed the earth underneath (outwards) long ago.
