Floating Foundation

By
Home Inspector with Jay Markanich Real Estate Inspections, LLC

Every now and then I run into something I have never seen before, like a floating foundation!

Brick facade house, nice addition on the side, masonry block foundation connected to the main house with a right angle.  Plenty of crawl space vents.

So far so good.

But when I got into the house, and looked into the crawl space I noticed that the last 5 concrete blocks of support are literally floating in the air!

Interestingly the other side was the same way!

Having never seen it before I shot off an email to an engineer friend of mine, with photos.

He had seen this before, saying that the construction crew left a hole there so they had more easy access to and from the crawl space under the room. 

Then they filled it in later. 

The sink hole bothered me too, beginning where you are looking and continuing down to just under where I am taking the photo.  That sink hole is about 6' deep!

The engineer said that moisture intrusion is the ultimate problem with this, and that he likes to see them finish by putting concrete under that floating portion, to help control water flow.

I sent his answer to my clients.  They had a couple more days in which to ask further questions if they wanted.

My recommendation:  when you see something odd or that you have never seen before, ask questions!  I never have a problem saying that I don't know something and will attempt to find out a valid answer.  My clients always appreciate that, and yours will too.

None Jim, in 12 years.  But, as the engineer said, the structure might be sound, but not recommended.  Sinking soil can never help!

Jay, I have heard of some huge sink hole in Quebec, but have never seen one (or heard of one) around here...

Sink holes happen all over, in small scales Chris.  It happened near here in the middle of a road!

Jay, hope this will be the only floating foundation you find this week!  See you Saturday.

Any foundation of Webster Street has likely been there for a while Pat!  And I don't remember seeing one before anywhere!
